Overview
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.
Features
- 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

LED Indicator Descriptions
| LED Indicator |
Status Description |
| RUN LED |
Ethernet port running indicator. After the Ethernet port is working normally, it outputs a square wave with a period of 2 seconds |
| STA LED |
MCU indicator. Flashes when the MCU is operating normally |
| TXD LED |
Transmit indicator, lights up when transmitting data |
| RXD LED |
Receive indicator, lights up when receiving data |
| Left Port Green LED |
Illuminates when Ethernet port 1 is connected to an Ethernet network |
| Right Port Green LED |
Illuminates when Ethernet port 2 is connected to an Ethernet network |
| Left Port Yellow LED |
Illuminates when a TCP connection is established. Can be used to check if a communication link is established between the module and the host software |
| Right Port Yellow LED |
Data activity LED. The state of this yellow LED changes when data is being transmitted over the Ethernet port, useful for determining if data transfer is occurring |
