1. 8CH Ethernet Relay Module: This product is an industrial 8ch relay module controlled via Ethernet port, adopts for RTU protocols, supports PoE power supply, also comes with an ABS rail mount case.
2. Easy to Use: The POE ETH Relay is very easy to use. Due to its fast communicating, stability, reliability, and safety, it is an ideal choice for industrial control equipments or applications with high communicating requirements.
3. Flash on off Function: Features flash on, flash off function, by passing argument to the command, it is possible to turn on the relay for a while and then close it automatically.
4. Safety: Supports relay control through for MQTT protocol, comes for MQTT application demo. Onboard optocoupler isolation, prevent the relay from being interfered by high voltage circuit.
5. LED Indicator: Adopts dedicated relay driver chip, with built in flyback diode guard, for stronger and more stable driving ability. 4 LEDs and network indicators for indicating the MCU status and signal transceiving status.
6. Opto Isolation: The switch input comes with bidirectional opto isolation, supporting both passive and active switch inputs, with a built in de jitter algorithm. The relay supports either switch input interlock mode or flip mode control.
