8-Channel Optocoupler Relay Module - DC5V PLC Control Board with Indicator Light

Technical Specifications

1. Optional supply voltages: DC 5V
2. Optocoupler isolation, drive current: 5mA; the input power supply and relay power supply can be either separate or shared.
3. VCC and GND are the power input terminals; the relay power input terminal is JD-VCC.
4. Relay control capacity: AC 220V/10A, DC 30V/10A.
5. Low-level (0V) trigger; the IN1-IN8 signal lines are active low.
6. The IN1-IN8 LEDs serve as relay status indicators: the LED lights up when the relay is energized (pulled in), and turns off when the relay is de-energized.

   I. Relay Switch Description

   1. When the relay coil is de-energized, the relay remains open, and the common terminal (COM) is connected to the normally closed terminal (NC). When voltage is applied to the coil, the relay pulls in, and the common terminal (COM) is connected to the normally open terminal (NO).
