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
* The external power supply adapter is NOT included by default, it is recommended to purchase 12V power supply if you need it.
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
