Description

12V Relay Module Switch Timer Delay Relay Shield with Optocoupler High and Low Level Trigger Module Thermal Control Module

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.
