Allen-Bradley 1747-KE DH-485 to RS-232C Interface Module – SLC 500 Series
Imagine a critical production line where your SLC 500 PLC cannot communicate with the host SCADA system or programming terminal — diagnostics are blind, remote monitoring is impossible, and every minute of downtime translates directly into lost output and costly manual intervention. The Allen-Bradley 1747-KE Interface Module exists precisely to eliminate this scenario. By bridging the DH-485 network to an RS-232C serial port, it restores the communication backbone that modern industrial automation depends on, making it an irreplaceable link in any SLC 500-based control architecture.
Within the SLC 500 product family, the 1747-KE occupies a specialized but essential role: it is the dedicated protocol gateway that allows legacy and contemporary serial devices — HMIs, computers, barcode scanners, and third-party controllers — to exchange data seamlessly with the SLC 500 CPU. Globally, the SLC 500 platform remains one of the most widely deployed mid-range PLC families in discrete manufacturing, food & beverage, and material handling, and the 1747-KE continues to be a sought-after component for both OEM machine builders and end-user maintenance teams keeping these systems operational.
