Features
The TTL/RS485 signal can be converted into a differential RS485 signal, support Full Duplex communication
Compatible with 3.3V ~ 5V TTL signal level, Power supply terminal with anti-reverse and anti-overvoltage circuit
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 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, switch via a Built-in jumper cap
Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
