This is a mini galvanic isolated TTL-to-RS485 serial converter, easy to integrate, with castellated holes with immersion gold process and compact size.

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, ensure 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.
