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

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.
Rail-mount case design
Rail-mount PC protective case, easy to install, safe to use
