TTL to RS485 Galvanic Isolated Converter (C)

This converter is designed for converting TTL signals to RS485 signals, supporting half-duplex communication. It has a TTL signal level of 3.3V to 5V and provides over-voltage protection. The compact, immersion gold design with castellated holes makes integration easy, and it features multiple protections, including a self-recovery fuse, a TVS diode for surge and spike suppression, and is lightning-proof.

It is ideal for expanding nodes and long-distance communication and it supports transmission distances up to 1.2km and up to 32 nodes.

Features

• 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
• Unibody power supply isolation, provides stable isolated voltage and needs no extra power supply for the isolated terminal
• Unibody digital isolation, allows signal isolation, high reliability, strong anti-interference, low power consumption
• TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning-proof & anti-electrostatic
• Self-recovery fuse and protection diodes, provide the current/voltage stable outputs, provide over-current/over-voltage protection, improve shockproof performance
• RS485 output terminal 120R resistor, enabled via soldering
• Black immersion gold process design, compact size, easy to integrate
