CT0001 - 4-Channel Isolated IO Relay Board Module

4 channel opto-isolated IO relay board. The optocouplers electrically isolate the control signal of each input from the corresponding mains rated relay output.

The inputs accept any trigger signal between 3 and 24V dc and the corresponding output will be activated and maintained till the input voltage decreases to zero.

An LED indicates each relays status. The board supply can be either 12V dc or ac and is reverse polarity protected. Screw terminal blocks for all connections.
