TTL To RS485 (C) converter, front view TTL To RS485 (C) converter, features
Features at a glance
  • Compatible with TTL/RS485 standard, converting the TTL signal into differential RS485 signal, supports half-duplex communication
  • Compatible with 3.3V ~ 5V TTL signal level, provides 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 self-recovery fuse and protection diodes, ensures the current/voltage stable outputs, provide over-current/over-voltage protection, improve shock proof performance
  • Onboard RS485 output terminal 120R resistor, enabled via soldering
  • Black immersion gold process design, compact size, easy to integrate
