This is a 30A 12V Power Relay Module With Optocoupler Isolation H/L Level Trigger for Arduino Relays.
Specifications:
This item is a 12-Volt Single Channel Relay interface board, It can be controlled directly by a wide range of microcontrollers such as 8051, AVR, PIC, ARM, DSP and so on.
Parameters :
12V Relay module SLA-12VDC-SL-C
Quiescent current: 5mA
Maximum current: 80mA
Trigger current: 2-4mA
Trigger power (low): 0-4V
High: 4.5-12V
Dimensions: 50 x 33mm
Pin Description
1. DC+: Module DC power supply anode (trigger terminal voltage anode)
2. DC-: Module DC power supply negative electrode (trigger terminal voltage negative electrode)
3. IN: Signal trigger terminal (default trigger voltage is the same as power supply)
4. JD+: Positive voltage of relay control terminal
5. JD-: The negative pole of the control terminal voltage of the relay
6. Short-circuit DC+ and JD+ with jumper caps and short-circuit DC- and JD- with jumper caps. The trigger terminal and the relay control terminal have the same voltage.
7. High- and low-level trigger mode selection, as shown in the figure, when the jumper is connected to the L terminal, the IN terminal is a low-level trigger, and when it is connected to the H terminal, it is a high-level trigger.
8. Normally closed terminal (NC): normally closed terminal of the relay
9. Common terminal (COM): relay common terminal
10. Normally open terminal (NO): Relay normally open terminal
