Cold junction compensation (CJC) is implemented to compensate for thermocouple reference junction temperature variations when interfacing with mixed-signal backplanes. The module requires KS8 connecting cables for field wiring termination, providing standardized connector interface for RTD element connections. Channel-to-channel isolation characteristics must be verified against system grounding requirements, as multiplexed RTD architectures share common return paths that may introduce ground loop currents in unbalanced field installations. The insulation resistance of at least 100 Mohm at 500 VDC and withstanding voltage of 500 VAC provide dielectric protection between field circuits and the DCS backplane.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003eQ: What type of connecting cable is required for the AMM32C module?\u003cbr\u003eA: The AMM32C requires KS8 connecting cables for field wiring termination to RTD sensing elements.\u003c\/p\u003e\n\u003cp\u003eQ: What is the insulation resistance specification of this module?\u003cbr\u003eA: The AMM32C provides insulation resistance of at least 100 Mohm when tested at 500 VDC, with a withstanding voltage rating of 500 VAC.\u003c\/p\u003e\n\u003cp\u003eQ: What is the operating temperature range for this RTD multiplexer module?\u003cbr\u003eA: The AMM32C operates within an ambient temperature range of 0 deg C to +50 deg C with humidity tolerance of 5% to 90% RH (non-condensing).\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the AMM32C module in the designated slot position per the DCS hardware manual. Ensure the backplane power supply is de-energized before inserting or removing the module. Use only approved KS8 connecting cables for field wiring termination to maintain signal integrity and connector compatibility. Route RTD sensor cables in shielded twisted-pair configuration with the shield grounded at the DCS cabinet only to prevent ground loops. Verify RTD element type (Pt100, Pt1000, Cu100, etc.) matches the module configuration before commissioning. Perform lead wire resistance compensation verification for 2-wire and 3-wire RTD connections. Confirm ambient temperature at the installation location does not exceed +50 deg C to maintain specified accuracy. Inspect all KS8 cable connectors for proper seating and locking mechanism engagement before applying power.\u003c\/p\u003e","brand":"Yokogawa","offers":[{"title":"Default Title","offer_id":52634907345176,"sku":"AMM32C","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/EC401-10S3_Cocoai_0d2e4ff2-f61c-4b5e-90cf-533c0d869d6c.jpg?v=1788860693","url":"https:\/\/www.innoplcsync.com\/products\/yokogawa-amm32c-rtd-input-multiplexer-module","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
