Industrial 8-Ch Ethernet Digital
Input / Output Module

Modbus Protocol And PoE Support, Linkage Control, DC 7V ~ 36V Power Supply

Features At A Glance

The Modbus POE ETH IO 8CH is an industrial 8DI / 8DO isolated digital input / output module with dual Ethernet interfaces control, it supports passive and active digital input. Adopts Modbus RTU / Modbus TCP protocols with built-in protection circuits such as power isolation, optocoupler isolation, resettable fuse, and TVS.

Onboard voltage regulator chip, supports 7V ~ 36V wide range power supply and PoE power supply
Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
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
The output utilizes Darlington transistor with optocoupler isolation for stronger driving capability, up to 500mA sink current, and built-in flyback diode protection
Features flash-on and flash-off functions, by passing arguments to the command, it is possible to turn on the output for a while and then turn it off automatically
Rail-mount case design, easy to install, safe to use
Onboard LEDs for indicating the input / output status, MCU status, and signal transceiving status

Primary Function

Supports Reading Digital Input By Sending Modbus RTU/TCP Protocol Commands Via Ethernet For Digital Output Control

Supports Multiple Communication Modes, Adopts Modbus Protocol

Supports TCP Server, TCP Client, UDP Mode, UDP Multicast, HTTP, MQTT,
And Supports Modbus RTU And 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 7V ~ 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.

Fully Isolated Digital Input / Output

Supports Passive And Active Digital Input (PNP Or NPN), With Power Isolation And Bi-Directional Optocoupler Isolation. Adopts Darlington Transistor Open-Drain Output, Up To 500mA Sinking Current Per Channel For Directly Driving Relays

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, blinking when sending data
RXD	RX indicator, blinking 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 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.
