i bought one of the RM1HLE 25v relay modules

http://www.lightobject.com/24V-relay-br ... -P840.aspx

to control my air pump from output 1 on the DSP board.

on the AC side, i assume i want to use COM and NO, but i'm a little confused by the CH1/VREF/DC-/DC+ on the switching side.

can someone post a wiring diagram of how they have theirs configured?

thanks!

I used like this relay with arduino and it has the same concept as in your case : CH1 is your signal input , DC- is ground and DC+ is DC Voltage.
hope this will help
