Extending Signal Duration for Zamel ROB-01 with Wiśniowski ST-01 Gate Controller

Umiar 1095 18
Best answers

Jak wydłużyć 0,5-sekundowy impuls z odbiornika Zamel ROB-01, aby sterownik bramy Wiśniowski ST-01 zadziałał na sygnał dłuższy niż 1 s?

Najprościej zastosować dodatkowy przekaźnik czasowy z funkcją „opóźnione wyłączenie”, który będzie wyzwalany impulsem z ROB-01 i poda na centralę bramy dłuższy styk zwierny [#18264081] Można użyć gotowego modułu, np. PCU-510, albo małego przekaźnika z dołączonym równolegle do cewki kondensatorem elektrolitycznym 1000–2000 µF, który przedłuży podtrzymanie po zaniku zasilania z odbiornika [#18264167] Wskazano też gotowy „przedłużacz czasu” do elektrozaczepu/napędu bramy na 12–24 V DC z firmy IMPULS w Warszawie; trzeba do nich zadzwonić, bo nie wszystko mają na stronie [#18264212][#18264835] Przy takim module wejście sterujące podłącza się do wyjścia Zamel, a na zaciskach należy znaleźć C i NO; biały przewód ma iść na wyjście Zamel, a zasilanie podać zgodnie z modułem [#18264484] Jeśli centrala ST-01 akceptuje bardzo krótki impuls, to może zadziałać bez dodatkowych przeróbek, ale z opisu wynika, że potrzebny jest jednak przekaźnik czasowy [#18264571]

    Good morning,
    i have such a problem:
    I bought a Zamel ROB-01 radio receiver to control the gate (wiśniowski st-01). But I haven't read that it only short-circuits the contacts for 0.5 sec, when my gate controller needs more than 1 sec. Apparently it is not possible to extend this time in ROB-01 itself - I don't know about that, such information I got from the manufacturer. I think, however, that it would be possible to use another switch of this type, which would be "triggered" by a signal from ROB-01 and which would short-circuit the contacts for a longer time, so that the gate would respond. However, I don't know where to look for something like that, I don't even know what to call it.
    Please help. Unless there is a simpler solution, I would also appreciate it.
    kind regards
    Grzegorz

    Isn't it simpler to return it and get another radio, e.g. Elmes?
    By the way, somehow I don't see any information about the timing of the output in the specification - it's possible you've wired it wrong.

    it would confuse me a bit, i already have a key to control theamele, i already have one rob-01 in the garage....
    now i would have to buy two new receivers and a transmitter.

    Hello .
    You can use an additional time relay, for example PCU-510, and connect it with the controller accordingly, or you can use a small relay, to which you connect (to its coil, in parallel) an electrolytic capacitor of significant capacity (1000-2000µF, or more), which, after the loss of power supply from the controller, will extend the time of holding this additional relay.

    That's right, but you can play around with this additional relay and capacitor, but for a different purpose and it has worked.

    oh that's right, I think that's what I'm looking for. But I don't see it in their range, or I don't know how to look for it....

    As for the doubt about the 0.5sec operation, it's not on their website but on the cardboard box there is this information - confirmed with the manufacturer.

    PS. I found something like this

    I appreciate the knowledge of my colleague, so please do so in my own way ;-) .
    Where do I plug in the ROB signal and where do I have the "extended" signal output to the gate?

    What didn't you understand in the previous sentence? I don't think it's any simpler, after all, the seller will probably also provide connection instructions.

    I apologise for my lack of knowledge, but I didn't understand how I was supposed to connect the gate to this device, i.e. which socket goes to the gate controller. I asked for a manual, the seller does not provide one in the kit.

    You connect the white wire to the Zamel outputs, the power supply is known and you have to find C and NO on the terminals using e.g. a meter.

Topic summary

✨ The discussion revolves around the Zamel ROB-01 radio receiver, which is used to control a Wiśniowski ST-01 gate controller. The main issue is that the ROB-01 only provides a short circuit for 0.5 seconds, while the gate controller requires a longer signal duration. Users suggest alternatives such as returning the Zamel receiver for a different model, like Elmes, or using an additional time relay (e.g., PCU-510) to extend the signal duration. Other solutions include connecting a relay with an electrolytic capacitor to prolong the output signal. The conversation also touches on the difficulty of finding specific components and connection instructions, with suggestions to contact suppliers for assistance.

FAQ

TL;DR: Extend a too-short ROB‑01 pulse using a time relay or a relay plus 1000–2000 µF; "You can use an additional time relay." This FAQ helps ROB‑01 users drive gate controllers that expect longer trigger times. [Elektroda, nikusert, post #18264167]

Why it matters: Without extending the pulse, the gate may ignore the trigger and fail to open.

Quick Facts

What’s causing the mismatch between ROB‑01 and ST‑01 timing?

ROB‑01 closes its contacts for about 0.5 s. ST‑01 needs a pulse longer than 1 s. The gate may not react to a 0.5 s closure. That timing mismatch is the root cause of the issue. [Elektroda, Umiar, post #18263972]

Can I extend the ROB‑01 pulse without changing radios?

Yes. Add a time relay to stretch the trigger or use a small relay with an electrolytic capacitor across its coil. Typical capacitor values are 1000–2000 µF. “You can use an additional time relay.” This preserves your current remotes and receiver. [Elektroda, nikusert, post #18264167]

What is a “time relay – delayed shutdown”?

It is a timer that holds its output closed after a short input, then opens after the set delay. It effectively converts a brief pulse into a longer contact closure suitable for the gate’s trigger input. “See under ‘time relay - delayed shutdown’.” [Elektroda, elkard, post #18264081]

How do I wire a time extender between ROB‑01 and the gate?

Use a pulse‑to‑delay relay module:
  1. Connect the module’s white signal wire to the ROB‑01 output.
  2. Power the module according to its rating.
  3. Identify C and NO with a meter, then wire C and NO to the gate’s trigger input. Set the hold time on the module to exceed 1 s. [Elektroda, sosarek, post #18264484]

Will a 0.5 s pulse drive a time relay reliably?

Often yes, but confirm the module’s minimum trigger time. Some need a longer input. “If it can be driven by such a short pulse then it should work.” Check module specs before ordering to avoid misfires. [Elektroda, sosarek, post #18264571]

Where do I get a compact extender module for this?

IMPULS (Warsaw) sells an electric door opener time extender with relay. It may not be listed online. “Call them and they’ll send it to you.” A referenced board size was 54 × 27 mm, which fits tight enclosures. [Elektroda, CYRUS2, post #18264835]

What power does the IMPULS extender need?

The board is powered from 12–24 V DC. That makes it easy to integrate with most low‑voltage gate control systems and accessories. It includes a relay for isolated switching. [Elektroda, CYRUS2, post #18264212]

Is swapping to a different radio cheaper than adding a time relay?

Yes, returning the ROB‑01 and buying another radio can cost less than adding a timer. As one pro put it, “It will be cheaper to return the Zamel and buy another radio.” Factor in re‑pairing remotes if you switch. [Elektroda, sosarek, post #18264174]

How do I extend hold time with a relay and capacitor?

Drive a small relay from the ROB‑01 and place an electrolytic capacitor (about 1000–2000 µF) in parallel with the coil. When the pulse ends, the capacitor discharges through the coil, holding contacts briefly closed. Increase capacitance for more hold time. Observe polarity on electrolytics. [Elektroda, nikusert, post #18264167]

I found a module with a white wire and C/NO/NC—how do I connect it?

Feed the white wire with the ROB‑01 pulse. Power the module per its rating. Identify C and NO using a meter, then wire those two to the gate’s trigger input. This creates the extended contact closure the controller needs. [Elektroda, sosarek, post #18264484]

Could I have miswired the ROB‑01 if the gate doesn’t react?

Yes. The output runtime isn’t obvious in some specs, so wiring mistakes happen. Verify the correct terminals and that the controller’s trigger input expects a dry contact. Recheck all connections before adding hardware. [Elektroda, sosarek, post #18263978]

How do I verify the 0.5 s pulse spec on ROB‑01?

Check the packaging label. The 0.5 s output duration is printed on the box and was confirmed with the manufacturer. It may not appear on their website, so the box is the authoritative reference here. [Elektroda, Umiar, post #18264400]

Will the seller include connection instructions for third‑party timer modules?

Not always. Some sellers do not include manuals with these small timer boards. Ask the seller before purchase, or be prepared to identify terminals with a meter. [Elektroda, Umiar, post #18264457]

I already use ROB‑01 elsewhere—why avoid switching radios?

Switching radios can force buying multiple new receivers and a matching transmitter. Staying with ROB‑01 and adding a timer preserves your existing setup and keys. That avoids re‑pairing and additional hardware costs. [Elektroda, Umiar, post #18263982]
