Overview of Allen-Bradley 1747-KE DH-485/RS-232C Interface Module

The Allen-Bradley 1747-KE is a communication interface module designed for the SLC 500 series that facilitates DH-485 and RS-232C communication protocols. It provides one DH-485 port, one DF1 communications port, and one configuration DF1 port. This module is a single slot device that mounts directly into any SLC 500 chassis and supports communication speeds from 300 to 19200 Kbps.

Key Features of Allen-Bradley 1747-KE

  • Communication Ports: One configuration port (9-pin Sub-D), one DF1 communication port (9-pin Sub-D), and one DH-485 communication interface (RJ-45).
  • Supported Protocols: DH-485, DF1, configurable for RS-232, RS-422, RS-423, and RS-485 communication.
  • Transmission Speeds: 300 to 19200 Kbps with cable distance dependent on protocol type.
  • Port Isolation: 500 VDC isolation between backplane to configuration port, backplane to DF1 port, and configuration to DF1 port.
  • Environmental Ratings: Operating temperature 0 to 60°C, storage -40 to 85°C, relative humidity 5-95% (non-condensing).
  • Compliance: UL / C-UL listed Class I, Division 2, Groups A, B, C, D; CE and C-Tick marked.
  • Power Consumption: 150 mA at 5V DC and 40 mA at 24V DC from the SLC 500 backplane.
  • Indicators: Eight LEDs for module diagnostics and operator interface.
  • Physical Size: 1 slot width, dimensions approx. 5.72 x 1.37 x 5.15 inches, weight about 0.37 pounds (168 grams).
