Feature:

Module description

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

2, the use of small optocoupler, strong anti-interference ability, stable performance; trigger current only needs 3mA;

3, the module working voltage is 5V/12V;

4, the relay is high level, the module contains current limiting resistor, the high level can be DC+, or the single chip I/O port can be set high;

5, fault-tolerant design, even if the control line is broken, the relay will not move;

6, power indicator (red), 1 relay status indicator (blue)

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

8, module size: 6.0cm * 3.0m * 2.5cm (length * width * height)

9, with 4 2.0MM diameter fixing bolt holes for easy installation

Module interface

Module control terminal: 4-wire interface, all interfaces have terminal blocks for user wiring

1, DC+: external DC power supply negative ( 5V/12V modules )

2, DC-: external DC power supply negative

3. VERF: The optical isolation control terminal refers to the ground wire. This signal should be connected to the negative pole of the power supply of the user control board.

4, CH1: relay control interface, high level (relative to VERF) corresponding relay pull-in

Specification:

Relay output: 3-wire interface, all terminals have terminal blocks

1. NO: The relay normally open interface, the relay is suspended before the suction, and the short is connected with COM after the suction.

2, COM: relay common interface

3. NC: The relay normally closes the interface, and the relay is shorted to COM before the suction is closed.

Package included:

1x 1-Channel Relay Module
