This 8-channel relay module from Waveshare offers reliable control and monitoring through dual Ethernet interfaces, PoE support, and Modbus RTU/TCP protocols. Housed in a DIN-rail ABS enclosure, it’s ready for cabinet or panel installation and suits automation applications that require fast, stable, and isolated relay control.
The onboard RS-485 and dual Ethernet ports support multiple communication methods, including TCP Server, TCP Client, UDP, UDP Multicast, and MQTT. You can daisy-chain multiple devices using Ethernet cascade, and power them via PoE (802.3af) or wide-range DC input (7–36V). Modbus and MQTT support make it easy to integrate with cloud servers or other industrial systems.
Eight digital inputs support both dry and wet contact signals with bi-directional optocoupler isolation and debouncing. Each relay can be independently configured and supports a contact rating up to 10A at 250VAC or 30VDC. LEDs indicate MCU and network status, and the onboard command feature allows temporary relay toggling via argument-based control.
Built-in protections include reverse connection prevention, flyback diode protection, and signal/power isolation. Configuration is simple via software or web browser, and DHCP/DNS support streamlines integration into existing networks.
