1. Compatible with RS232/RS485 standard, converting the RS232 signal into balanced differential RS485 signal
2. Stable transmission at the rate of 300~115200bps
3. Onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
4. Onboard unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
5. Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
6. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
7. Integrates optional RS485 output terminal 120R resistor, enabled/disabled via a switch
8. The onboard power supply screw terminal allows 6V~36V DC wide-range input
9. Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
