Waveshare Industrial 8-Ch Ethernet Digital Input/Output Module, Modbus RTU / TCP Protocol, Supports PoE Power Supply, With Various Isolation And Protection Circuits
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.
User Manual / Datasheet / Example Codes Etc.
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
