Product Details

The XY-017 is an industrial-grade TTL to RS485 converter module designed for reliable serial communication in environments with high electromagnetic interference. Unlike basic converters, this module features automatic flow control, eliminating the need for a "Receive/Transmit" enable pin, and includes integrated hardware protection such as lightning strikes and anti-static measures.

Specifications

  • Operating Voltage: 3.3V to 5.0V (Compatible with both logic levels)
  • Data Rate: Standard serial baud rates (up to 500Kbps)
  • Transmission Distance: Up to 800 meters (using 850m 2*1.5 cable; recommended within 800m)
  • Operating Temperature: -40°C to +85°C (Industrial grade)
  • Bus Capacity: Supports up to 128 nodes on the same bus
  • TTL Interfaces:
    • VCC (Power)
    • TXD (Transmit)
    • RXD (Receive)
    • GND (Ground)
  • RS-485 Interfaces:
    • A (Non-inverting signal)
    • B (Inverting signal)

Features

  • Automatic Flow Control: Hardware-based automatic direction switching allows for seamless communication using only RX and TX lines, simplifying code and hardware requirements.
  • Industrial Protection: Features 600W lightning and surge protection, $\pm$15KV ESD (static) protection, and a 120-ohm termination resistor (optional/onboard).
  • Signal Integrity: Designed with high-quality thick copper traces and impedance matching to maintain signal quality over long cable runs.
  • Status Indicators: Includes RXD and TXD signal indicator LEDs for real-time monitoring of data transmission and reception.
  • Global Compatibility: Standard 2.54mm pitch headers for the TTL side and 5.08mm screw terminals for the RS-485 bus side.

Common Applications

  • Industrial automation and Modbus RTU networking
  • Remote data acquisition and long-distance sensor monitoring
  • Building security systems and access control
  • Smart home energy monitoring (Smart Meters)
