Features
Compatible with TTL/RS422 standard, converting the TTL signal into differential RS422 signal, support full duplex communication
Compatible with 3.3V ~ 5V TTL signal level, provides anti-reverse and over-voltage protection for power supply interface
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 TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, anti-electrostatic
Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
Onboard RS422 input and output terminal 120R resistor, enabled/disabled via jumper
