Industrial Rail-Mount TTL To RS485 Serial Converter Electrical isolation Converter

   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

Primary Function

Converting The TTL Signal Into Balanced Differential RS485 Signal

For Interface Converting, Expanding Nodes And Long-Distance Communication



Rail-Mount Support

Easy To Combine Multi Rail-Mounted Serial Server Together, More Freely



Multiple Protection, Safe And Stable

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, lightningproof & anti-electrostatic. Onboard resettable fuse and protection diodes, ensures the current/voltage stable outputs, provides over-current/over-voltage protection, improves shock resistance
