The module processes analog field signals across 24 isolated input channels, digitizing raw 4-20 mA DC currents via high-precision A\/D converters. By converting field signals into standardized digital values at 2 samples per second per channel, the hardware eliminates ground loops and mitigates high-impedance voltage drops before transmitting process data over the system backplane.\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\u003eA2H124-24FX P0973BJ\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\u003e0.6 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e10.2 cm x 10.2 cm x 15.2 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eRedundant DC inputs via baseplate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Channels\u003c\/td\u003e\n\u003ctd\u003e24 Isolated Analog Inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Type\u003c\/td\u003e\n\u003ctd\u003e4-20 mA DC (Two-Wire Transmitters)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConversion Resolution\u003c\/td\u003e\n\u003ctd\u003e12 to 16-bit A\/D\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMeasurement Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/- 0.1% of span\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel-to-Logic Isolation\u003c\/td\u003e\n\u003ctd\u003e1500 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProcess Control \u0026amp; Channel Isolation Profiles\u003c\/h3\u003e\n\u003cp\u003eThe module maintains signal integrity within dense DCS architectures using dedicated channel-to-channel and 1500 VDC channel-to-logic galvanic isolation. This isolation barrier prevents common-mode noise propagation, voltage spikes, and ground loop interference across the 24 input channels. Internal firmware monitors input loop health continuously while supporting standard 4-20 mA HART loop protocol communications. System processors read incoming field transmitter telemetry directly, while diagnostic algorithms verify channel accuracy and flag out-of-spec conditions to maintain process reliability.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Does the module support hot-swapping during active system operation?\u003c\/p\u003e\n\u003cp\u003eA: Yes. Technicians can replace the module without shutting down the system backplate or interrupting power to adjacent I\/O modules on the baseplate assembly.\u003c\/p\u003e\n\u003cp\u003eQ: What termination assembly is required to connect the field wiring to this module?\u003c\/p\u003e\n\u003cp\u003eA: Field wiring requires connection through the compatible P0973BJ termination assembly to route the 24 isolated 4-20 mA DC signals correctly to the module interface terminals.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module indicate channel diagnostic status or hardware faults?\u003c\/p\u003e\n\u003cp\u003eA: The front panel features LED status indicators tied to internal firmware diagnostics, providing immediate local visualization of power input status, system communication faults, and individual channel health.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cp\u003eMount the baseplate on a standard DIN rail or enclosure rack frame, verifying rigid structural alignment prior to module insertion. Insert the module firmly into its baseplate slot until the mechanical locking mechanism engages completely. Ensure field cables connect to the dedicated P0973BJ termination assembly, maintaining proper wire routing separation between low-level signal pairs and AC power conductors to limit electromagnetic crosstalk.\u003c\/p\u003e\n\u003cp\u003eGround the baseplate backplane chassis to plant earth through a heavy-gauge copper conductor. Connect signal cable shields at a single grounding point, typically at the DCS cabinet terminal strip, to block ground currents from entering the 1500 VDC isolated input channels. After completing wire terminations, inspect the enclosure for proper IP20 compliance and verify that operating ambient temperatures inside the cabinet remain between -20 and +70 deg C.\u003c\/p\u003e","brand":"Foxboro","offers":[{"title":"Default Title","offer_id":43931365605466,"sku":"A2H124-24FX P0973BJ","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/466._a6f9d404-510e-4a53-a474-7ee9aed1e648.jpg?v=1787904228","url":"https:\/\/www.spareoil.com\/products\/foxboro-a2h124-24fx-p0973bj-i-a-series-analog-input-modules","provider":"SpareOil Automation","version":"1.0","type":"link"}
