Allen-Bradley 1770-KFD

Overview

The Allen-Bradley 1770-KFD is a communication interface module that provides conversion between RS-232 (DF1 protocol) and RS-485 (HART protocol). Commonly used in process control applications, it enables a personal computer or PLC to communicate with HART field devices via a standard COM port. The unit is DIN rail mountable and powered by 24V DC, making it easy to integrate into industrial control panels.

Key Features

  • Interface Conversion:

    • RS-232 (DF1) to RS-485 (HART)

  • Power Supply: 24V DC

  • Mounting: DIN rail

  • Connection Ports:

    • DB-9 serial (RS-232)

    • Terminal block (RS-485/HART)

  • LED Indicators: Power and communication status

  • Protocols Supported: DF1 (Allen-Bradley) to HART

  • Isolation: Optical and galvanic isolation between ports

  • Baud Rate: 1200 bps (typical for HART communication)

Technical Specifications

  • Catalog Number: 1770-KFD

  • Operating Voltage: 24V DC ±10%

  • Current Draw: Approx. 100 mA

  • Operating Temperature: 0°C to +60°C

  • Mounting Style: DIN rail

  • Dimensions (H x W x D): Approx. 100 x 22.5 x 120 mm

  • Certifications: UL, CE, CSA

  • Enclosure Rating: IP20 (for control cabinet use only)

Applications

  • HART modem communication setup

  • Process control with analog transmitters

  • Configuration of HART-compatible devices

  • Integration of field instruments into PLC systems

  • PC-based diagnostic and monitoring tools

Why Choose the 1770-KFD

  • Reliable and proven interface for HART communications

  • Compact and easy-to-install DIN rail housing

  • Compatible with most HART configuration software

  • Essential tool for bridging legacy DF1 and HART protocols
