Description

12V Relay Module 1 Channel Optocoupler Isolation High and Low Level Trigger Power Supply Module For Arduino

Feature

"1, the module uses genuine quality relay normally open interface maximum load: AC 250V/2A, DC 30V/2A;

2, using optocoupler isolation, strong driving ability, stable performance; trigger current 5mA;

3, The module voltage is 5V, 9V, 12V, 24V available;

4. The module can be set as high or low trigger by jumper;

5. Fault-tolerant design, even if the control line is damaged, the relay will not operate;

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

7. Humanized interface design, all interfaces can be directly connected to wires through terminal blocks, which is very convenient

8. Module size: 50*26mm*18.5mm (L*W*H)

9. There are four fixing bolt holes, the holes are 3.1mm, and the spacing is 44.5mm*20.5mm

Two module interfaces:

1, DC+: Positive power supply (voltage required by the relay, there are 5V.9V.12V and 24V options)

2, DC-: Negative power connection

3, IN: high or low level control relay

Relay output:

1, NO: relay normally open interface, pull the front and rear vacant relay short circuit and COM

2, COM: general interface relay

3. NC: Normally closed relay interface, short-circuit with COM before the relay, and then leave it empty

High and low level trigger selection ends:

1. When the low jumper is shorted the low lever triggers;

2 When the high jumper is shorted and the high leverage is triggered. "
