Datasheet

Channel1 Interface

COM1 - Common pin

NC1 - Normally Closed. Will be connected with COM1 when RELAY1 pin is set low
and disconnected when RELAY1 is high;

NO1 - Normally Open. Will be connected with COM1 when ŸRELAY 1 pin is set
high and disconnected when RELAY1 is low;

4 DIGITAL PINS TO CONTROL 4 ŸRELAYS

RELAY1-RELAY4 pins could be connected directly with Arduino pin number of 7-4,
so that four relays could be easily controlled by the Arduino
