Internal terminal compensation networks support direct connection of thermocouples and RTDs, providing uniform thermal referencing required for cold junction compensation (CJC) circuits while suppressing common-mode noise on connected 4-20 mA HART loop protocol lines.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What isolation voltage is maintained between field wiring and system logic on the P0972QR?\u003c\/p\u003e\n\u003cp\u003eA: The module provides 2,000 V RMS isolation between the field terminals and system processing electronics.\u003c\/p\u003e\n\u003cp\u003eQ: What signal input ranges are supported by the P0972QR termination channels?\u003c\/p\u003e\n\u003cp\u003eA: The 32 channels support voltage signals from -40 VDC to +80 VDC and current signals from -20 mA to +20 mA.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the P0972QR module vertically onto the system DIN rail or mounting rack, verifying that side retention clips engage securely with the chassis frame. De-energize all field circuits and power sources before connecting or disconnecting terminal connections.\u003c\/p\u003e\n\u003cp\u003eStrip field conductor ends to recommended lengths and clamp securely into the screw compression terminals. Separate low-voltage analog wiring from high-voltage AC cables in cabinet wire ducts. Route signal cable drain shields to the main cabinet single-point ground bar. Where field cables enter through threaded conduit, ensure NPT fittings achieve a minimum of 5 full threads of engagement to maintain physical strain relief and shield integrity.\u003c\/p\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":53397881192757,"sku":"P0972QR","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/P0924JH_b1882db3-f6dd-4d56-9ed6-f8084ab722d7.png?v=1787621221","url":"https:\/\/www.5gplc.com\/products\/p0972qr-termination-assembly-module-foxboro","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
