2 Channel Relay Module with Optocoupler Isolation High&Low Level Trigger Module(12V)

1、The module uses high-quality relay, the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A.

2、Using patch optocoupler isolation, strong driving ability, stable performance; trigger current 5mA.

3、The module working voltage is available in 5V, 9, 12V, 24V.

4、The module can be triggered by a jumper to set a high level or a low level.

5、Fault-tolerant design, even if the control line is broken, the relay will not move.

Features:

The module uses high-quality relay, the maximum load of the normally open interface: AC 250V/10A, DC 30V/10A.

Using patch optocoupler isolation, strong driving ability, stable performance; trigger current 5mA.

The module working voltage is available in 5V, 9, 12V, 24V.

The module can be triggered by a jumper to set a high level or a low level.

Fault-tolerant design, even if the control line is broken, the relay will not move.

Power indicator (green), relay status indicator (red).

The interface design is user-friendly, all interfaces can be directly connected through the terminal block, very convenient.

Specification:

Module Size:50 x 41 x 18.5mm / 1.97 x 1.61 x 0.73in

Hole Diameter: 3.1mm/0.12in

Hole Interval Distance:44.5 x 35.5mm / 1.75 x 1.4in

Wiring Diagram:

DC+: Connect the positive pole of the power supply (the voltage is required by the relay, there are 5V.9V.12V and 24V selection).

DC-: connected to the negative pole of the power supply.

IN1:1 signal signal trigger terminal, you can set the high or low level control relay to pull in.

IN2: 2 channel signal trigger terminal, you can set the high or low level control relay to pull in.

Relay output:

NO1: 1 channel relay normally open interface, the relay is suspended before the suction, after the suction and short circuit with COM1.

COM1:1 channel relay common interface.

NC1: 1 channel relay normally closed interface, short circuit connection with COM1 before the relay is closed, suspended after suction.

NO2: 2 channel relay normally open interface, the relay is suspended before the suction, after the suction and short circuit with COM2.

COM2: 2 channel relay common interface.

NC2: 2-channel relay normally closed interface, short-circuit with COM2 before the relay is closed, and float after the suction.

High and low trigger selection:

1. S1 is a high-low trigger selection for 1 relay;

2. S2 is the high and low level trigger selection of 2 relays.

3 com is shorted with low, the corresponding relay is triggered by low level, and when com is shorted with high terminal, it is triggered by high level.
