The Waveshare 8-ch Ethernet Relay Module (B) is a versatile and robust device designed for industrial and automation applications. This module features eight relay channels that can be controlled via Ethernet using Modbus RTU or Modbus TCP protocols, making it highly suitable for remote control and monitoring.
Features:
- 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
- Supports DC 7~36V wide range power input and PoE power supply
- Supports relay control through MQTT protocol, comes with Alibaba Cloud MQTT application demo
- Onboard Optocoupler isolation, prevent the relay from being interfered by high-voltage circuit
- Adopts dedicated relay driver chip, with built-in flyback diode protection, for stronger and more stable driving ability
- Supports passive and active digital input, with bi-directional optocoupler isolation, built in debouncing algorithm. The relay supports digital input linkage control or toggle control
- Reverse-proof circuit, prevent the circuit from being damaged accidentally by incorrect connection
- High quality relay, contact rating: ≤10A 250VAC/30VDC
- Rail-mounted ABS plastic enclosure, easy to install, safe to use
- 4 LEDs and Network indicators for indicating the MCU status and signal transceiving status
