Product Descriptions

Input interface:

1. DC+: Connect to the positive pole of the power supply

2. DC -: Connect to the negative pole of the power supply

3. IN1-IN4: Depending on the settings of each channel, the corresponding relay can be controlled to close at high or low levels

Relay output terminal:

12 wire interface, all interfaces can be directly wired out

NO1--NO4: The relay is normally open, suspended before closing, and short circuited to COM after closing

COM1--COM4: Relay common terminal

NC1--NC4: The normally closed end of the relay is short circuited to the COM before being pulled in, and suspended after being pulled in

High and low level trigger selection terminal

1. S1-S4 are the high and low level trigger selection for relays 1-4 in sequence

When COM is short circuited to LOW, the corresponding relay is triggered at a low level, and when COM is short circuited to HIGH, it is triggered at a high level
