  Features At A Glance  

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
