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
