Welcome to our store!

1、Using patch optocoupler isolation, strong driving ability, stable performance. Trigger current is 5mA.
2、The operating voltage of the module is 5V, 12V, 24V for selection.
3、Each way of the module can be triggered by high or low level through a jumper setting.
4、Fault-tolerant design, even if the control line breaks, the relay will not move.
5、Power indicator light (green), 4-way relay status indicator light (red).

Module interface: r
1. DC + : connected to the positive pole of the power supply (voltage required for relay, 5V, 12V and 24V for selection) r
2. DC- : connect to the negative pole of the power supply. r
3. IN1-IN4: according to the setting of each circuit, the corresponding relay can be controlled by high or low level to suck in. r
r
Relay output terminal: with 12 lines of interface, all interfaces can be directly connected to the wiring, convenient for users to use r
1. NO1--NO4: the relay normally open interface, and the relay is off before it is sucked in, and is connected to COM after it is sucked in. r
2. Common interface of relay COM1--COM4. r
3. NC1--NC4: relay normally closed interface. The relay is short-circuited with COM before it is sucked in and off after it is sucked in. r
r
High and low level trigger selection terminal: r
1. S1-S4 are the high-low level trigger selection for relay 1-4 channels in sequence; r
2. Com and low short connection, the corresponding relay for low level trigger, com and high short connection for high level trigger. r
