100-240Vac mains powered 4 channel opto-isolated IO DPDT relay board. The 4N25 optocouplers electrically isolate the control signal of each input from the corresponding DPDT 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.
Negative trigger input terminals can be daisy-chained together using header jumpers on JP1, JP2 and JP3 (not included - Order Code JUMPER-RED).
An LED indicates each relays status. The power input has reverse polarity protection. Screw terminal blocks for all connections.
