This module converts raw field transmitter loop currents into structured backplane data values for controller processing. Operating across a standard 0-20 mA current range, the hardware manages signal sampling, filtering, and loop excitation to maintain real-time process monitoring precision without control loop update delays.\u003c\/p\u003e\n\u003ch3\u003eSuffix Breakdown \u0026amp; Model Matrix\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e1C31174\u003c\/strong\u003e: Base Ovation electronic printed circuit board and card assembly designator.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eG03\u003c\/strong\u003e: Specific group hardware revision defining the 0-20 mA current range calibration and component layout.\u003c\/li\u003e\n\u003c\/ul\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\u003e1C31174G03\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eEmerson\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\u003e1.00 lbs (0.45 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Ovation I\/O card footprint\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e0 to 60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003ePowered via Ovation controller backplane bus\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Range\u003c\/td\u003e\n\u003ctd\u003e0-20 mA current loop\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eAnalog Loop Electronic Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol and Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe 1C31174G03 module features high-density channel-to-channel isolation to prevent electrical ground loops and common-mode noise from corrupting low-level current signals. The internal current-sensing circuits support standard 0-20 mA operational spans and retain compatibility with 4-20 mA HART loop protocol device pass-through communication. Built-in cold junction compensation (CJC) algorithms and thermal drift suppression maintain precise analog-to-digital conversion parameters during ambient cabinet temperature fluctuations.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1C31174G03 module process 4-20 mA signal inputs in addition to 0-20 mA spans?\u003c\/p\u003e\n\u003cp\u003eA: Yes, the module's 0-20 mA current loop hardware covers standard 4-20 mA operational ranges via software scale configuration within the Ovation control system software.\u003c\/p\u003e\n\u003cp\u003eQ: Is hot-swapping supported for the 1C31174G03 module on an active Ovation base?\u003c\/p\u003e\n\u003cp\u003eA: Module removal or replacement on an energized backplane must strictly follow Ovation field maintenance procedures; power and field loops should be isolated to prevent current transients.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDisconnect incoming primary power feeds to the Ovation rack and field current loops before inserting or extracting the card.\u003c\/li\u003e\n\u003cli\u003eWear an ESD wrist strap attached to panel earth ground to protect internal analog conversion components from static discharge.\u003c\/li\u003e\n\u003cli\u003eAlign the module circuit board with the designated slot guide rails and push firmly until the locking levers engage the base unit.\u003c\/li\u003e\n\u003cli\u003eUse shielded twisted-pair cables for all 0-20 mA field loop wiring, keeping run lengths separate from high-voltage AC motor lines.\u003c\/li\u003e\n\u003cli\u003eConnect cable shielding drain wires directly to the central enclosure earth ground bus using low-impedance ground leads.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Emerson","offers":[{"title":"Default Title","offer_id":66751369314419,"sku":"1C31174G03","price":233.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/1C31157G03_Cocoai_e2f3a434-5192-48f0-9b66-8c69f048e1e1.jpg?v=1790754654","url":"https:\/\/www.dcssupplier.com\/ar\/products\/emerson-1c31174g03-process-control-modules","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
