Bolt Hole: 3.1 mm; 44.5*20.5mm (spacing)
Voltage: 5V, 12V, 24V (Optional)
Module interface:
1. DC + : connected to the positive pole of power supply (voltage is required for relay, 5V, 12V and 24V for choice)
2. DC- : connect to the power negative pole.
3. IN: high or low level control relay suction
Relay output terminal:
1. NO: relay changeover interface,relay suction front suspension, suction and COM short connection.
2.COM: Relay common interface.
3.NC: Relay normally closed interface,relay suction and COM short joint, suction clearance.
High and low level trigger selection terminal:
1. When jumper is connected with LOW short circuit, it is triggered by LOW level;
2. High level is triggered when jumper is connected with high short circuit;
