The component ingests high-accuracy electrical telemetry across integrated AC current, DC current, and DC voltage physical interface nodes. By calculating waveforms from multi-range CT links and instrument loops, the module services localized digital fault recording (DFR) and real-time regulation routines over active internal processing buses.\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\u003eD25-0157-000003\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGE Fanuc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOrigin\u003c\/td\u003e\n\u003ctd\u003eTechnical specifications determine factory origin\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003eInternal hardware option selection dependent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard D25 series chassis envelope requirements apply\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003eIndustrial grade environmental classification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eBase processor draw plus active measuring channel configuration loads\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal CT Input Options\u003c\/td\u003e\n\u003ctd\u003e1 A rms or 5 A rms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAC Measurement Range\u003c\/td\u003e\n\u003ctd\u003e2% to 1600% of nominal; 2% to 4200% (asymmetrical) for DFR\/protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermal Overload Limits\u003c\/td\u003e\n\u003ctd\u003e4x nominal continuous; 30x nominal for 10 seconds; 100x nominal for 1 second; 10-minute duty cycle for parameters exceeding 4x nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAC Accuracy Metrics\u003c\/td\u003e\n\u003ctd\u003eAccuracy: +\/-0.5% to +\/-0.3% of nominal; Frequency: +\/-0.03 Hz; Phase Angle: +\/-0.5 deg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC Current Ranges\u003c\/td\u003e\n\u003ctd\u003e+\/-1 mA, +\/-5 mA, +\/-10 mA, +\/-20 mA nominal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC Current Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-0.10% of full scale\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC Voltage Input Span\u003c\/td\u003e\n\u003ctd\u003eNominal: +\/-5 Vdc; Measurement range: +\/-6 Vdc\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDC Voltage Accuracy\u003c\/td\u003e\n\u003ctd\u003e+\/-0.05% of full scale\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eProfinet \/ EtherNet\/IP Deterministic Networks Integration\u003c\/h3\u003e\n\u003cp\u003eThe module manages input scaling through its internal analog-to-digital matrix, utilizing fixed software filtering blocks to maintain firmware flash compatibility across concurrent operating cycles. High-density I\/O registers serialize the +\/-20 mA DC current loops and +\/-6 Vdc voltage inputs into the memory map, isolating transient electrical noise from the primary processor backplane communication channel. This architectural separation preserves deterministic communication performance, preventing host communication packet peaks from delaying the 1 ms fault-recording triggers managed by the AC protection circuits.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How is the 4200% asymmetrical AC current measurement range managed by the DFR firmware without causing memory overflows?\u003c\/p\u003e\n\u003cp\u003eA: The onboard analog-to-digital conversion matrix reserves dedicated high-headroom registers for transient surge inputs. When an asymmetrical fault step occurs, the internal scaling algorithms automatically track the over-range parameter without impacting firmware flash compatibility or disrupting concurrent DC loop sampling.\u003c\/p\u003e\n\u003cp\u003eQ: Can the CT input terminals be disconnected while the primary power lines are under load?\u003c\/p\u003e\n\u003cp\u003eA: No. Disconnecting active CT loops causes high-voltage open-circuit transients that can destroy the low-burden input resistors. The secondary current paths must be externally shorted or fully isolated before servicing any analog connector blocks on the D25-0157-000003.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEarthing and Grounding Frame\u003c\/strong\u003e: Bond the metal chassis ground screw directly to the main cabinet copper ground bus bar using a low-impedance grounding cable before routing any instrumentation lines.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAC Input Shielding\u003c\/strong\u003e: Run all AC current transformer connections through dedicated twisted-shielded pairs, terminating the shield grounding braid strictly at the enclosure wall plate to block inductive interference.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow-Voltage Cable Trailing\u003c\/strong\u003e: Route the +\/-5 Vdc voltage and low-current DC signal lines in distinct wiring ducts isolated from primary high-voltage AC switches and inductive control relay circuitry.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":53047662936373,"sku":"D25-0157-000003","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/D25-0157-000003.png?v=1782725634","url":"https:\/\/www.5gplc.com\/products\/ge-fanuc-d25-0157-000003-measurement-and-control-device","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
