Rail-mount TTL To RS232 (B)

Galvanic isolated Serial Port Converter

Features at a glance

• 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, lightningproof & 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
