TTL To RS485 (C) Galvanic Isolated Converter, Half-Duplex Communication, Lightningproof & Anti-Surge, Multi-Isolation Protection

【Product Details】

TTL To RS485 (C) Galvanic Isolated Converter

Castellated Holes With Immersion Gold process, Compact size, Easy to integrate



【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
