5V 8-Channel Relay Module

الوصف

Module description

1. The relay normally open interface maximum load: AC 250V/10A, DC 30V/10A;
2. With optocoupler isolation, strong drive capability, stable performance; trigger current 5mA;
3. Module working voltage: DC 5V
4. Each channel of the module can be triggered by a jumper to set a high level or a low level;
5. Fault-tolerant design, even if the control line is disconnected, the relay will not move;
6. With status indicator: power (green), 8-channel relay status indicator (red)
7. All module size interfaces can be directly connected through the terminal block, which is convenient and practical.
8. Module size: 138 x 56 x 18mm (length * width * height)
9. With 4 fixing bolt holes, hole 3.1mm

Module interface

1. DC+: Connect to the positive of the power supply.
2. DC-: Connect the negative of the power supply.
3. IN1-IN8: According to the setting of each channel, the corresponding relay can be controlled by high or low level.

Relay output

1. NO1–NO8: Relay normally open interface.
2. COM1–COM8 relay common interface
3. NC1–NC8: Relay normally closed interface.

High and low trigger selection

When COM and LOW connected, the corresponding relay is triggered by low level, and when COM and HIGH connected, it is triggered by high level.
