Description

Product selling point：

1: Wide range of applications

2: Simple to use

3: Small size

4: stable performance

5: Three voltage specifications are optional

Module Description:

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

SMD optocoupler isolation, strong driving ability, stable performance; trigger current 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 user-friendly, and all interfaces can be directly connected through the terminal block, which is very convenient

Two module interface:

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

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

3. IN: low level control relay pull-in

Relay output:

1. NO: relay normally open interface, the relay is suspended before closing, and short-circuited with COM after closing

2. COM: relay common interface

3. NC: relay normally closed interface, short-circuit with COM before the relay pulls in, and hangs after pull-in
