Used this in place of an elevator call button that operates on 120v. If you look at the relay on the back, it is a standard PCB mount relay and is rated at 120-240vac @ 3 amps... Again, this is a typical pcb mount you'd find in all sorts of electronics. Instructions are horrible but if you have some intuition, you know what you're doing and have electrical/electronic troubleshooting skills you should be able to make it work. Not sure what all the gripe is about the built in relay on the thing. I measured the current on the elevator setup and saw about 625 mA, the relay can handle at least 4 times that. Measure the current through the load you are driving to determine if you need a larger relay to be driven by the onboard relay and try to stay decently well below its limit. If you do need a relay, I would suggest a solid state relay. It can be tampered with and somebody with some know how could defeat it, however, it does have a spring loaded tamper switch that could be utilized to trigger an existing alarm system or siren. No problems programming it, a little tinkering with the meter (hint: continuity) and it works nicely so far. On some of the connection points I found 12vdc, I'm assuming some of the other reviewers are using this 12vdc to drive their load and not just the powering the common on the PCB relay directly. I suspect this COULD be the issue some people are having with it malfunctioning over time and I would not suggest using it like this as its possible that the current draw of the load is being yanked through the units supply line causing premature failure, just a thought. Again, the author of the instructions for this thing could definitely use more than a little guidance in their utilization of the english language ;) Overall, I think it's pretty nice for the price. I removed one star because if power is lost, the relay is triggered upon restoration of power (like an outage) and allows access momentarily if someone is there at that particular time I haven't found a way to prevent it, again, more investigation needed. In this application it shouldn't be that big of a deal. Last thing, I have not seen any video or anyone using this unit quite like I am (120vac on the PCB relay). I did not follow the instructions much because they are useless. I looked at the relay and seen its rating, and then used my multimeter to probe for 12 volts while it was powered on and enabling the relay. Used continuity test to see which pins are connected through relay and verified 12vdc was not present on those connection points while relay was in both states before connecting 120v to it.

I love this. But my internal relay started acting up after a few months with about 30 - 100 uses per day. We were driving the electric door strike directly off this keyboard relay. On the new one we bought we added an SSR relay to drive the door strike, that should hopefully move the high current load onto the SSR (easy to replace an SSR every few years in a easy to access location vs installing and programming a new keyboard)

For the price... This gizmo is great... Does what it is supposed to do... If you are buying this with the hopes of protecting your horde of gold, You might want to pass... For interior doors or cabinets that need to be a bit more secure... It will work fine... NOTE: Make sure you use a relay on the outputs. The circuitry in the unit is not designed to handle any large current loads...
