Features
Compatible with TTL/RS232 standard, converting the TTL signal into RS232 signal, supports 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, lightn-ingproof & anti-electrostatic
Onboard protection diodes, ensure the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock proof performance
Onboard power supply screw terminal, allows 3.3V~5V DC input
Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
