BESTEP 1 Channels 24V Relay Module High and Low Triggering Blue Plate

Module Description:

1. The module adopts genuine quality relay, the maximum load of normally open interface: AC 250V/10A, DC 30V/10A;
2. Using double optocoupler isolation, strong drive capacity, stable performance; trigger current 5mA;
3. Each channel of the module can be triggered by high or low jumper level;
4. Fault-tolerant design, even if the control line is broken, the relay will not move;
5. Power indicator (green), 1 relay status indicator (red)
6. User-friendly interface design, all interfaces can be directly connected through the wiring terminals, very convenient

Module interface:

1. DC+: Connect to the positive pole of the power supply (the relay voltage is 5V)
2. DC-: Connect to the negative pole of the power supply
3. ON: The relay can be controlled by high-level or low

Relay output:

1. NO: Relay normally open interface, before the relay is vacant, it will be shorted to COM after picking up
2. COM: Relay common interface
3. NC: Relay normally closed. Before the relay is closed, it is short-circuited with COM.

High and low-level trigger selection:

1. S1 is the high and low-level trigger selection of relay 1;
2. When com is shorted to low, the corresponding relay is a low-level trigger. When com is short to high, it is a high-level trigger
