Designed to mount in a Bulletin 1771 I\/O chassis, it provides the serial-side interface used to connect programming terminals, modems, or other devices to a PLC-5 Data Highway network. The KF2 supports either point-to-point or multi-drop configurations on the DH\/DH+ network, enabling flexible legacy installations. As part of the 1770 KF2 family, it acts as a bridge between a PC or serial device and Allen-Bradley PLC-5 Data Highway networks. Key characteristics include an asynchronous serial interface compatible with RS-232-C and RS-422-A and the ability to connect to DH or DH+ networks for PLC-5 control systems. Typical applications include maintaining or integrating legacy PLC-5 installations where serial devices must communicate with the PLC-5 Data Highway, such as programming terminals or local HMIs.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46244001153258,"sku":null,"price":43.0,"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-1770-kf2-plc-module","provider":"GTG Hardware","version":"1.0","type":"link"}
