Features:
1. Compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, support half-duplex communication
2. Compatible with 3.3V ~ 5V TTL signal level, provides anti-reverse and over-voltage protection for power supply interface
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, lightningproof & 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. Onboard RS485 output terminal 120R resistor, enabled/disabled via switch
8. Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
