Allen-Bradley 1747-KE SLC 500 Interface Module

The Allen-Bradley 1747-KE is a DH-485/DF1 Interface Module for the SLC 500 family that provides an RS-232 DF1 path between a host computer and an installed SLC 500 controller. Mounted in an SLC 500 chassis, it offers a non-isolated DH-485/DF1 interface to connect a PC or terminal with DF1 protocol over RS-232 for remote programming, troubleshooting, and data extraction from the controller’s data table. It supports both full- and half-duplex DF1 communication and uses Belden 9463 as the standard communications cable; the RS-232/DF1 connections are carried on six-pin Phoenix-style connectors. Power is drawn from the SLC backplane, requiring both 5 V DC (up to 150 mA) and 24 V DC (up to 40 mA). Physical dimensions measure 5.72 inches in length, 1.37 inches in width, and 5.15 inches in height, with a weight around 0.37 lb. Typical configurations include linking to an 1747-AIC Advanced Interface Coupler for multi-node DH-485 networks, sometimes using 1747-C13 cables to establish the connection, and it resides in the same chassis as the SLC 500 processor. The unit is rated for operation from 0 to 60 C, providing a compact serial gateway that extends RS-232 access to SLC 500 devices without modifying the DF1 software on the controller.
