Compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, supports half-duplex communication. Compatible with 3.3V ~ 5V TTL signal level, provides 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, lightningproof & anti-electrostatic
Onboard self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock proof performance
Onboard RS485 output terminal 120R resistor, enabled via soldering. Black immersion gold process design, compact size, easy to integrate
