Module size:
1: 50*25 * 18.5MM
2-way: 50*41 * 17.5MM
4-way: 75*51 * 16.5MM
Module interface:
1. DC +: connect to the positive pole of the power supply (the voltage is in accordance with the requirements of the relay)
2. DC-: connect to the negative pole of the power supply
3. IN: high or low Levcon level control relay snap
Relay output:
1. NO: the relay is normally open. The relay is suspended before being sucked and shorted with COM after being sucked
2. COM: relay common interface
3. NC: Relay normally closed interface, relay shorted with COM before snap-in, suspended after snap-in
high and Low Level trigger selection terminal:
1. When wire jumper and LOW are shorted, it is triggered at LOW level;
2. When the wire jumper and high are shorted, it is triggered at a high level.
Package Including:
1 x Relay Module Board
