Waveshare Industrial Dual Ethernet Ports 8-ch Relay Module(C), PoE Power Supply(30544)

Description

1. Dual Ethernet port design, support communication and PoE power supply cascade
2. With flash-on and flash-off functions, the relay can be controlled by command to automatically close after being turned on for a period of time
3. Support DC7V-36V wide voltage power supply, support PoE Ethernet power supply
4. Support control of relays through MQTT protocol, and provide Alibaba Cloud MQTT application routines
5. Onboard optocoupler isolation to avoid interference from relay high-voltage circuits
6. Adopt special relay driver chip with built-in freewheeling diode protection, with stronger and more stable driving ability
7. The switch input has bidirectional optocoupler isolation, supports passive and active switch input, built-in de-jitter algorithm, and the relay supports switch input linkage mode or flip mode control
8. Onboard anti-reverse connection circuit to avoid reverse connection of positive and negative poles and burnout of the circuit
9. High-quality relays are used to allow access to loads: less than or equal to 10A250VAC or less than or equal to 10A30VDC
10. Guide rail ABS protective shell, easy to install and use, safer with shell
11. External 4 LED indicators and network port indicators, you can easily check the MCU status and signal receiving and sending status
