1. Product description

8DI8RO module is 8 channels digital isolated input, 8 channels relay isolated output, output through the RS485 interface.

The module uses the standard Modbus RTU communication, adapts many kinds of software, PLC, DCS and so on. The module power supply, RS485 communication electrical signals isolated from each other, effectively inhibit the series mode and common mode interference.

Using RS485 MODBUS RTU standard communication, configuration software, PLC and industrial touch screen can form network.
Signal control, power supply, RS485 communication electrical signals isolated from each other.
Communication circuit with lightning protection, anti-interference, power polarity protection.
Communication circuit lightning protection, anti interference.
RS485 communication signal output interface with over-voltage over-current double protection
Signal acquisition and control can be widely used in industrial field devices.
Communication format can be set by software.
This module has hardware watchdog and output protection mechanism to protect your equipment.

The MCU will be reset in 2 cases. One is when the MCU is dead. The other is that the master station does not send data to the slave module, the module will reset the MCU after 6 seconds. The output protection mechanism is very necessary.

For example, when a digital output module controls a motor, the master station keeps the motor in operation. If the 485 bus is disconnected, when the master wants to send a signal to disconnect the motor, the slave module will not receive data, then the motor will be running, there is a security risk.

With this function, the module constantly checks itself. When the 485 network fails,the module will automatically disconnect the output.This avoids accidents.
