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
