The module processes 16 isolated analog input channels accepting standard 4-20 mA DC transmitter signals across a 12-bit to 16-bit analog-to-digital conversion scale. Operating on a nominal 24 VDC backplane power feed with an 8 W power dissipation profile, the rack-mounted hardware maintains full channel-to-channel and channel-to-system galvanic isolation to suppress common-mode electrical noise across redundant Fieldbus communication paths.\u003c\/p\u003e\n\u003ch3\u003eHardware Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eP0926GQ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eFoxboro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.74 kg (1.63 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e23 cm x 22 cm x 6 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 deg C to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e~8 W at 24 VDC nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAnalog Input Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Input\u003c\/td\u003e\n\u003ctd\u003e16 channels, 4-20 mA DC range\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResolution\u003c\/td\u003e\n\u003ctd\u003e12-bit to 16-bit A\/D conversion\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGalvanic Isolation\u003c\/td\u003e\n\u003ctd\u003eChannel-to-channel and channel-to-system isolation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Bus\u003c\/td\u003e\n\u003ctd\u003eFoxboro I\/A Series redundant Fieldbus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiagnostics\u003c\/td\u003e\n\u003ctd\u003eIntegrated channel health monitoring, watchdog, and status LEDs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temp\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Humidity\u003c\/td\u003e\n\u003ctd\u003e5% to 95% non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control \u0026amp; DCS Instrument Integration\u003c\/h3\u003e\n\u003cp\u003eThe analog input fieldbus module conditions pressure, temperature, flow, and level transmitter telemetry before broadcasting digitized process variables to central control processors. When interfacing field instruments operating over the 4-20 mA HART loop protocol, internal galvanic isolation barriers decouple sensor wiring loops, eliminating ground loops that corrupt signal accuracy. Continuous internal diagnostic routines run in the background to verify A\/D conversion linearity, sense wire integrity, and backplane health, illuminating front-panel LEDs to indicate channel faults without interrupting real-time control execution.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does channel-to-channel galvanic isolation prevent system-wide signal degradation?\u003c\/p\u003e\n\u003cp\u003eA: Optical and transformer barriers isolate each 4-20 mA current loop independently. An electrical short or ground potential shift on one field transmitter remains isolated to that channel, preserving normal operation across the remaining 15 inputs.\u003c\/p\u003e\n\u003cp\u003eQ: Is live insertion and removal supported during active controller operation?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the hot-swappable module incorporates staggered pin connectors on the rear interface, ensuring frame ground and 24 VDC power engage before data communication lines to prevent signal bus interruption during online maintenance.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBackplane Insertion:\u003c\/strong\u003e Align module card edges with the carrier frame guides and press firmly until the locking mechanism latches the backplane connector into place.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShield Line Termination:\u003c\/strong\u003e Connect field wiring cable shields directly to the dedicated cabinet earth ground bus bar, keeping drain wires short to maximize high-frequency noise suppression on 4-20 mA loops.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable Channel Isolation:\u003c\/strong\u003e Route 4-20 mA analog input cables in separate wireways away from high-voltage AC power lines, motor leads, and switching inductive loads.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Feed Verification:\u003c\/strong\u003e Ensure the 24 VDC system power supplies maintain voltage regulation within specified tolerances before energizing the baseplate carrier assembly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Clearance:\u003c\/strong\u003e Maintain at least 50 mm of unobstructed ventilation space above and below the module rack to support convective air cooling across internal components.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":43969266286682,"sku":"P0926GQ","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/482_0f52be5f-f4f7-4280-a18a-379e4a2bf924.jpg?v=1788168257","url":"https:\/\/www.spareoil.com\/products\/foxboro-p0926gq-fbm-analog-input-modules","provider":"SpareOil Automation","version":"1.0","type":"link"}
