Features At A Glance

This product is an 8-ch relay module designed for industrial environments, featuring dual Ethernet interfaces control and 8 digital inputs. It adopts Modbus RTU / Modbus TCP protocols, supports Ethernet port cascade and PoE power supply, also comes with an ABS rail-mount case.

The Modbus POE ETH Relay (C) is very easy to use. Due to its fast communication, stability, reliability, and safety, it is an ideal choice for industrial control equipments and/or applications with high communication requirements.

  • Dual Ethernet ports design, supports Ethernet port communication cascade and PoE power supply cascade
  • Features flash-on, flash-off function, by passing arguments 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

 

Primary function
Supports reading digital input by sending Modbus protocol commands via Ethernet for relay output control

Supports Multiple Communication Modes, Adopts Modbus Protocol
Supports TCP Server / TCP Client / UDP Mode / UDP Multicast / MQTT
Supports Modbus RTU / Modbus TCP protocols

Multi Configuration Methods
Supports software and Web Browser Configuration, Obtaining Dynamic IP Via DHCP, connecting to domain name server via DNS protocol

Multi Power Supply Options, Wide Range Power Input
DC Power port: directly uses a power plug for power supply;
Screw terminal: DC 7~36V wide range power input;
PoE port: IEEE 802.3af PoE compliant

Note: 12V Adapter not included.

Digital Input
Supports passive (dry contact) and active (wet contact) digital input, with bi-directional optocoupler isolation

 

Interfaces & Indicators
With Multiple LED Indicators, Easy To Monitor The Operating Status

 

RUN Ethernet port indicator, blinking when Ethernet port is normally working
STA MCU indicator, blinking when the MCU is normally working
TXD TX indicator, lights up when sending data
RXD RX indicator, lights up when receiving data
Left Ethernet port Green Indicator Lights up when the connection of Ethernet Port 1 is established
Right Ethernet port Green Indicator Lights up when the connection of Ethernet Port 2 is established
Left Ethernet Port Yellow Indicator Lights up when the TCP connection is established
Right Ethernet Port Yellow Indicator Data activity indicator, blinking when transmitting data

 

Multiple modes for various automation scenarios

Supports multiple relay control modes, each channel supports independent
control mode setting

Note: Except for linkage mode, all other modes also support relay control via commands.

 

Support Ethernet Port Cascade and PoE cascade power supply

Onboard 2-ch Ethernet Ports for communication and cascade
Either one can be used for dual serial server network communication, while the other one can be used for cascading or communication with other devices

Note: Each module in the cascade needs to be powered individually or using PoE cascade power supply. The maximum power consumption of a single module is 7W, please pay attention to the output power of Router when using PoE cascade power supply.

Relay connection

Contact rating of the onboard relay up to 10A 250VAC/30VDC

Enclosure Design

Rail-mounted ABS plastic enclosure, easy to install, safe to use
