Product details
Onboard power and signal isolation, provide stable isolated voltage, high reliability and strong anti-interference. Onboard TVS (Transient Voltage Suppressor), effectively suppress surge voltage and transient spike voltage in the circuit, anti-electrostatic. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock resistance
TTL TO RS422 (B) is an industrial-grade rail-mounted electrically isolated TTL-to-RS485 serial converter.
Features:
- Compatible with TTL/RS422 standard, converting the TTL signal into differential RS422 signal, support 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, anti-electrostatic
- Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock resistance
- Onboard RS422 input and output terminal 120R resistor, enabled/disabled via jumper
- Industrial rail-mount ABS case design, small in size, easy to install, and cost-effective
