It mounts in a 1771 I\/O chassis and provides the Data Highway link that lets a PLC-2 processor communicate with other Data Highway devices. The KA enables peer-to-peer data exchange and remote I\/O communication across the DH network, extending the reach of a PLC-2 installation beyond the local processor rack. In typical deployments, the KA connects the PLC-2 controller to Data Highway devices such as remote I\/O racks, intelligent peripherals, and operator interface devices that reside on the same DH network, enabling status updates, data sharing, and coordinated control across a factory floor. The module is used as part of Allen-Bradley’s Data Highway communications family and relies on compatible PLC-2 hardware and cabling to form a functional DH network. As a dedicated communication adapter, the 1771-KA bridges the controller and the DH network, providing a stable interface for data exchange without requiring additional software or gateways.\u003c\/p\u003e\u003c\/div\u003e","brand":"Allen-Bradley","offers":[{"title":"New","offer_id":46244011114730,"sku":null,"price":2900.0,"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-ka-communication-adapter-module","provider":"GTG Hardware","version":"1.0","type":"link"}
