## Description

Industrial 8-Ch Digital Input & Output Module, DC 7~36V Wide Voltage Power Supply, Modbus RTU Protocol, Multiple Isolation Protection Circuits, Rail-Mount Support 8-ch Digital Input & Output module

### Features

This is an industrial grade 8DI / 8DO digital isolated input & output module with RS485 control interface. Supports passive / active input, adopts Modbus RTU protocol with built-in protection circuits such as power isolation, magnetical isolation, resettable fuse, and TVS.

- Configurable device address (1~255), multi devices can be cascaded on RS485 bus
- Onboard voltage regulator, supports 7~36V wide range power supply
- Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal
- Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference
- Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic
- Supports passive and active digital input, with bi-directional optocoupler isolation, built in debouncing algorithm. Supports DI/DO linkage control or DO toggle control
- The output utilizes Darlington transistors with optocoupler isolation, provides stronger driving capability with up to 500mA sinking current, built in flyback diode protection
- Features flash-on, flash-off function, by passing argument to the command, it is possible to turn on the output for a while and then close it automatically
- Rail-mount case design, support stacking combination, easy to install and safer to use
- Multiple LEDs for indicating the input & output status, MCU status and signal transceiving status
