24V 1 channel
Drive current: 5mA
Power supply voltage:+24VDC
Equipped with 4 positioning holes with a diameter of 3.1mm for easy bolt fixation

Module Interface
DC+: Connected to the positive pole of the power supply (voltage according to relay requirements)
DC -: Connected to the negative pole of the power supply
IN: The relay can be controlled to engage at high or low levels

Relay output terminal:
NO: Normally open interface of the relay, suspended before the relay is pulled in, and short circuited to COM after pulling in
COM: Relay Common Interface
NC: Normally closed interface of the relay, short circuited to COM before relay engagement, suspended after engagement
High and low level trigger selection terminal
1. When the jumper is shorted to LOW, it is triggered at a low level;
When the jumper is short circuited to high, it is triggered at a high level.

Package include:
Relay module * 1（5V 9V 12V 24V optional）
