Industrial Converter 8-Ch Ethernet IO Module to Modbus RTU / TCP Protocol with 2 PoE ports - Waveshare 33917

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.

1. Onboard voltage regulator chip, supports 7V ~ 36V wide range power supply and PoE power supply

2. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal

3. 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

4. The output utilizes Darlington transistor with optocoupler isolation for stronger driving capability, up to 500mA sink current, and built-in flyback diode protection

5. 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

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

7. Onboard LEDs for indicating the input / output status, MCU status, and signal transceiving status

Primary function
