This TTL to RS485 module compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, support half-duplex communication
The TTL converter with onboard unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
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
Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
