DC5V 4 Channel Red Color Relay Module

This is a DC5V 4 Channel Red Color Relay Module With Optocoupler Isolation Supports High and Low Voltage Trigger. The low level triggers the relay module’s power indicator (green) and the 4-way relay status indicator (red). User-friendly interface design, all interfaces can be directly connected through the terminal leads. Four fixing bolt holes are provided. Fault-tolerant design, the relay will not move even if the control line is disconnected.

The relay module is isolated by a chip-type optocoupler, which has strong driving capability and stable performance. The trigger current is 5mA. Each path of the module can be triggered by a high or low level by a jumper setting. The 4-channel relay module has an operating voltage of 5V, 12V and 24V.

Features:

1. Maximum load:AC 250V/10A, DC30V/10A

2. SMD optocoupler isolation, strong driving ability, stable performance; trigger current 5mA

3. the module voltage 5V

4. each channel module can be set high or low triggered by jumper

5. fault-tolerant design, even if the control line is broken, the relay will not operate

6. power indicator (green), 4 relay state indicator (red)

7. interface design user-friendly, all interfaces are available through the wiring terminal direct connection leads, very convenient
