Product Description

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

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
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

Primary function

Converting the TTL signal into balanced differential RS485 signal for interface converting, expanding nodes and long-distance communication

Multiple Protection, Safe And Stable

Onboard power and signal isolation, provide stable isolated voltage, high reliability and strong anti-interference. Onboard Lightningproof Diodes and TVS (Transient Voltage Suppressor), effectively suppress 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, provides over-current/over-voltage protection, improves shock proof performance

Compact And Easy Integration

Castellated Holes With Immersion Gold Design, Highly Integrated PackagingSupports Multiple Ways To Be Embedded Into Various Product Applications

Interface Introduction

INDICATORS
- R (RXD): RX indicator, lights up when the TTL port receives data

- PWR: Power indicator, lights up when there is power supply connection and voltage is detected
Left side interface
- PE: RS485 signal ground
- B-: RS485 differential signal B-
- A+ RS485 differential signal A+
Right side interface
- GND: Ground / TTL signal ground
- RXD: TTL receive data pin
- TXD: TTL transmit data pin
- VCC: DC 3.3V~5V power supply
