Designed to support four high-density current loops, the unit uses internal 12-bit analog-to-digital converters to translate 0-20 mA and 4-20 mA field signals with 250-ohm input termination. Onboard firmware flash compatibility ensures synchronized parameter configuration and factory-calibrated scaling offsets across all RX3i backplane rack slots without drift over operating temperature gradients.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the IC694ALG221 analog input module support hot-swapping during backplane operation?\u003c\/p\u003e\n\u003cp\u003eA: No, hot-swapping is not supported. Power to the baseplate rack and field terminal connections must be isolated before insertion or removal of the module.\u003c\/p\u003e\n\u003cp\u003eQ: What are the backplane internal power consumption requirements for this module?\u003c\/p\u003e\n\u003cp\u003eA: The module draws 25 mA from the +5 VDC backplane logic supply and 100 mA from the isolated +24 VDC external power bus.\u003c\/p\u003e\n\u003cp\u003eQ: What is the input conversion rate and response time for processing all analog channels?\u003c\/p\u003e\n\u003cp\u003eA: The module features a 2 ms update time to evaluate and update digital values for all four input channels concurrently.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDisconnect backplane main power and field circuit wiring before seating the module into the baseplate slot.\u003c\/li\u003e\n\u003cli\u003eAlign the module card edges with the RX3i backplane guide rails and press firmly until top and bottom latches secure the chassis.\u003c\/li\u003e\n\u003cli\u003eWire 0-20 mA or 4-20 mA process loops to the removable 20-screw terminal block using shielded twisted-pair cabling.\u003c\/li\u003e\n\u003cli\u003eConnect the signal cable drain shield strictly to a single panel chassis ground point to prevent ground loop currents across the 200 V common mode voltage barrier.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"GE Fanuc","offers":[{"title":"Default Title","offer_id":43725287981146,"sku":"IC694ALG221","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/IC694ALG221.png?v=1784884569","url":"https:\/\/www.spareoil.com\/ar\/products\/ge-fanuc-ic694alg221-pacsystem-rx3i-analog-input-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
