I read somewhere that instead of using a DMX Relay board ($120+-) you could just use a standard DMX Dimmer Pack ($50+-) and buy some 120v relays at radio shack (item 275-217).
So I got a few of these radio shack relays and wired them up and tested them by just plugging them in the wall. I was able to complete the (dry contact) circuit i wanted with this set up.
I am now using my newly purchased DMX Dimmer Pack and I got the pack to work just fine with a light but not the relay.
I set it up in VSA as a DMX Relay and going from 0-254 (as a relay, not dimmer) the light turns on and off just as it should. Now when I plug the relay in place of the light, the relay never turns all the way off?
I tested the volts and when the dimmer pack is turned on (via VSA) the radioshack relay gets 119+- volts (as it should) and the relay completes the circuit, but when the dimmer pack is turned off (via VSA), the relay is still getting like 50+- volts? So the relay buzzes and hummes and stays connect so the circuit never disconnects?
I have unplugged the relay and plugged a light in and again everything works fine, its just the pack is send to many volts to the radioshack relay when it should be off.
