This product is an industrial 8-channel relay module controlled via an Ethernet port, featuring 8-channel digital input. It supports Modbus RTU and Modbus TCP protocols, offers PoE power supply, and comes in an ABS rail-mount case. Designed for ease of use, it ensures fast communication, stability, reliability, and safety, making it an ideal choice for industrial control equipment or applications requiring high-speed communication.

Features
  • Supports reading digital inputs via Modbus RTU protocol commands and controlling relay output based on input signals.
  • Compatible with TCP Server, TCP Client, UDP Mode, UDP Multicast, HTTP, MQTT, Modbus RTU, and Modbus TCP protocols.
  • Allows software and web browser configuration, supports dynamic IP assignment via DHCP, and connects to domain name servers via the DNS protocol.
  • Includes a flash-on/flash-off function, enabling relays to turn on for a specified duration before automatically switching off.
  • Supports a wide input voltage range of DC 7V–36V and PoE power supply.
  • Enables relay control through the MQTT protocol and includes an Alibaba Cloud MQTT application demo.
  • Utilizes a dedicated relay driver chip with built-in flyback diode protection for enhanced stability and driving capability.
  • Supports both passive and active digital input with bidirectional optocoupler isolation and an integrated debouncing algorithm. The relay allows digital input linkage or toggle control.
  • Features a reverse-proof circuit to prevent damage from incorrect wiring.
  • Housed in a rail-mounted ABS plastic enclosure for easy installation and safe operation.
  • Equipped with four LEDs and network indicators to display MCU status and signal transmission.
