The module operates as an interface component within the 1771 I\/O chassis, transferring communication data through the PLC backplane.\u003c\/p\u003e\n\u003cp\u003eThe Allen-Bradley PLC-5 architecture uses backplane communication for module data exchange. The 1771-KE supports Data Highway network connectivity and RS-232-C serial communication, allowing connection with compatible external communication equipment.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What communication interfaces are available on the 1771-KE module?\u003cbr\u003eA: The module provides Data Highway and RS-232-C communication ports for PLC-5 system communication functions.\u003c\/p\u003e\n\u003cp\u003eQ: What is the backplane current requirement of the 1771-KE?\u003cbr\u003eA: The module requires 750 mA backplane current and operates from the PLC-5 chassis 5 VDC supply.\u003c\/p\u003e\n\u003cp\u003eQ: Does the 1771-KE require an external power supply?\u003cbr\u003eA: No external power supply is specified. The module receives operating power through the PLC-5 backplane.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eInstall the 1771-KE module in a compatible Allen-Bradley 1771 I\/O chassis slot with backplane power removed during insertion or removal. Verify rack power capacity before installation to maintain the required backplane current availability.\u003c\/p\u003e\n\u003cp\u003eConnect Data Highway and RS-232-C communication wiring according to the applicable PLC-5 system wiring requirements. Route communication cables separately from high-voltage power conductors to reduce electrical interference. Maintain proper cable shielding and connect shields according to the control system grounding practice.\u003c\/p\u003e\n\u003cp\u003eConfirm communication parameters, including serial interface settings, before placing the module into service. Inspect connectors and wiring arms for proper mechanical engagement during installation.\u003c\/p\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":43681508753498,"sku":"1771-KE","price":123.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0612\/4601\/3530\/files\/1771-KE2.jpg?v=1784534796","url":"https:\/\/www.plcmasters.com\/products\/allen-bradley-1771-ke-plc-5-communication-controller-module","provider":"PLC Masters Ltd.","version":"1.0","type":"link"}
