When coupled with a field termination assembly equipped with a Cold Junction Reference (CJR), internal firmware algorithms automatically execute cold junction compensation (CJC) and non-linear thermocouple linearization. This processing maintains accurate 16-bit analog-to-digital signal conversion across extreme ambient fluctuations without requiring intermediate 4-20 mA transmitters or external conditioning hardware.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the FBM202 require an external Cold Junction Reference (CJR) for thermocouple processing?\u003c\/p\u003e\n\u003cp\u003eA: The module executes cold junction compensation automatically when wired to a compatible field termination assembly that incorporates an integrated CJR sensor element.\u003c\/p\u003e\n\u003cp\u003eQ: What level of electrical isolation does the FBM202 provide between individual input channels?\u003c\/p\u003e\n\u003cp\u003eA: The module features complete galvanic isolation between individual channels as well as between field-side input circuitry and the internal system backplane logic.\u003c\/p\u003e\n\u003cp\u003eQ: Is the FBM202 capable of operating in redundant hardware configurations?\u003c\/p\u003e\n\u003cp\u003eA: Yes, two FBM202 modules can be configured as a redundant pair on standard I\/A Series baseplates to enable automatic failover protection without interrupting thermal data transfer.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eSeat the module directly into its designated slot on the I\/A Series baseplate or rack frame, ensuring the retention latches engage firmly to establish reliable backplane bus connection. Ensure the field enclosure maintains an IP65 ingress protection level and that ambient temperatures remain within the rated -40 to +70 deg C operating window.\u003c\/p\u003e\n\u003cp\u003eConnect all thermocouple and millivolt signal pairs to the corresponding field termination assembly using dedicated extension wire. Route low-voltage thermocouple wiring away from high-voltage AC cables and switching drive conduits to avoid electromagnetic noise induction. Ground overall cable shields at a single ground bus point on the cabinet frame to preserve 16-bit signal integrity across all 8 channels.\u003c\/p\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":43096019435610,"sku":"FBM202","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/305_572f8fc8-118e-46e9-b252-6bbe3d0d6dd4.jpg?v=1774256873","url":"https:\/\/www.spareoil.com\/products\/foxboro-fbm202-i-a-series-8-channel-thermocouple-input-module","provider":"SpareOil Automation","version":"1.0","type":"link"}
