{"product_id":"allen-bradley-1771-kf-communication-control-module","title":"Allen-Bradley 1771-KF Communication Control Module","description":"\u003cdiv\u003e\u003cp\u003eAllen-Bradley 1771-KF Communication Control Module is a Data Highway (DH) RS-232-C interface module that bridges intelligent RS-232 devices to a PLC-5 DH network. As a stand-alone Data Highway Communication Controller, it mounts in a Bulletin 1771 I\/O chassis and enables direct, peer-to-peer communication with other 1771 KE\/KF modules to extend the DH data path to RS-232 peripherals. The 1771-KF provides an RS-232-C interface for devices such as terminals, printers, or modems, allowing bidirectional data exchange with a PLC-5 processor over the Data Highway without requiring a separate gateway. This module is part of Allen-Bradley’s 1771 family and is described in Rockwell Automation literature as a means to link intelligent RS-232-C devices to the data highway, including guidance on connection topology and addressing. Typical applications include shop-floor serial device integration for monitoring, data logging, and remote query or control of equipment attached to PLC-5 systems, where a robust serial link must ride along the DH network. The KE\/KF family modules are designed for compatibility with PLC-5 DH networks and are referenced in official documentation as facilitating peer-to-peer communications between DH modules and RS-232 devices.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244011278570,"sku":null,"price":33.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-079.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/allen-bradley-1771-kf-communication-control-module","provider":"GTG Hardware","version":"1.0","type":"link"}
