Operating within EtherNet\/IP deterministic networks, the hardware incorporates WAVERSAVER mechanical vibration rejection software filtering to stabilize weight readings above 0.25 Hz. Firmware flash compatibility and dynamic I\/O density scaling allow integrated C2 electronic calibration without requiring physical test weights across continuous batching processes.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How many load cells can be powered directly from a single 1769-WS weigh scale module?\u003c\/p\u003e\n\u003cp\u003eA: The module supplies a regulated 5 VDC excitation voltage capable of driving up to four 350-ohm load cells or sensors connected in parallel.\u003c\/p\u003e\n\u003cp\u003eQ: What calibration methods does the 1769-WS module support within the controller software?\u003c\/p\u003e\n\u003cp\u003eA: The unit supports both traditional calibration using certified test weights and Hardy C2 electronic calibration, which reads internal calibration data stored inside C2-certified load cells.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDisconnect system backplane power before inserting or removing the 1769-WS module from the CompactLogix sub-rack rail.\u003c\/li\u003e\n\u003cli\u003eRoute strain gauge load cell signal cables in dedicated low-voltage instrument conduits separated from AC power conductors and motor drives.\u003c\/li\u003e\n\u003cli\u003eGround cable shield braids at the designated system enclosure earth bus bar to maximize noise rejection performance.\u003c\/li\u003e\n\u003cli\u003eVerify that total load cell bridge resistance remains above the minimum allowable impedance threshold before applying 5 VDC excitation.\u003c\/li\u003e\n\u003cli\u003eTighten terminal block retaining screws and module DIN rail latches to maintain reliable backplane bus connector alignment.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Allen-Bradley","offers":[{"title":"Default Title","offer_id":52637828841752,"sku":"1769-WS","price":270.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/1769-WS_3db989cb-5697-4178-a451-dcecb5d627a9.png?v=1788920715","url":"https:\/\/www.innoplcsync.com\/products\/allen-bradley-1769-ws-compactlogix-weigh-scale-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
