Product Introduction

1 way electromagnetic relay module optical coupling isolation low level trigger PLC control driver board

Module description:

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

It adopts chip optocoupler isolation, which has strong driving ability and stable performance, and the trigger current is 5mA;

Fault tolerant design, even if the control line is broken, the relay will not act;

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

The interface design is humanized, and all interfaces can be directly led out through the wiring terminals, which is very convenient.

Two module interface:

1. DC +: connected to positive pole of power supply (3.3V)

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

3. In: low level control relay closing

Relay output:

1. No: normally open interface of relay, which is suspended before closing and short circuited with com after closing

2. COM: relay common interface

3. NC: normally closed interface of the relay. The relay is short circuited with com before closing and suspended after closing
