Features
Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal
Stable transmission at the rate of 300~115200bps
Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
Integrates optional RS485 output terminal 120R resistor, enabled/disabled via a switch
The onboard power supply screw terminal, allows 6V~36V DC wide range input
Industrial rail-mount ABS case
