Designed with integrated signal conditioning networks, the unit performs hardware filtering, open\/short-circuit loop fault detection, and sensor linearization on each channel. The assembly draws 20 mA at 24 VDC auxiliary supply across an operating temperature spectrum of -40 to 70 deg C.\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\u003eFC-GMLA16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eHoneywell\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\u003e0.35 kg (0.77 lbs)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e96 mm x 96 mm x 60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e20 mA at 24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Count\u003c\/td\u003e\n\u003ctd\u003e16 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Type\u003c\/td\u003e\n\u003ctd\u003e4-20 mA current loops\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIngress Protection\u003c\/td\u003e\n\u003ctd\u003eIP65 rated\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDiagnostic Functions\u003c\/td\u003e\n\u003ctd\u003eOpen-circuit and short-circuit detection per channel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Processing\u003c\/td\u003e\n\u003ctd\u003eHardware filtering, sensor linearization, calibration reference adjustment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eChannel-to-Channel Isolation \u0026amp; 4-20 mA Loop Processing\u003c\/h3\u003e\n\u003cp\u003eThe FC-GMLA16 integrates individual channel-to-channel isolation networks alongside 4-20 mA HART loop protocol compatibility to prevent field-side ground loops from corrupting central logic processor signals. Internal isolation transformers and transient suppression arrays attenuate high common-mode voltages and electrical noise induced across long field transmitter wire runs. By maintaining signal conditioning and channel isolation at the termination level, the module guarantees analog input accuracy without burdening backplane communication processing nodes.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the FC-GMLA16 handle field wiring fault detection on active analog loops?\u003c\/p\u003e\n\u003cp\u003eA: Internal monitoring circuits evaluate loop current thresholds continuously, triggering diagnostic fault bit assertions when current levels fall below open-circuit limits or exceed short-circuit bounds.\u003c\/p\u003e\n\u003cp\u003eQ: What grounding procedure must be observed during installation of 4-20 mA field loops?\u003c\/p\u003e\n\u003cp\u003eA: Shielded twisted-pair wiring shields must be bonded to a single cabinet earth ground point at the FTA terminal block to avoid circulating ground currents.\u003c\/p\u003e\n\u003cp\u003eQ: Is external power filtering required for the 24 VDC power supply connection?\u003c\/p\u003e\n\u003cp\u003eA: The board contains onboard power conditioning and transient suppression logic; however, a regulated 24 VDC source with voltage stability within nominal industrial tolerances must be supplied.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDe-energize the 24 VDC main field power supply before connecting or disconnecting field wiring terminals on the module.\u003c\/li\u003e\n\u003cli\u003eMount the enclosure securely within an IP65-compliant panel arrangement or DIN rail layout maintaining clearance for convective heat dissipation.\u003c\/li\u003e\n\u003cli\u003eTerminate 4-20 mA transmitter loops using shielded twisted-pair cables, ensuring drain wires connect strictly to designated earth chassis ground bars.\u003c\/li\u003e\n\u003cli\u003eVerify channel polarity matching on field loop connections prior to restoring 24 VDC auxiliary power.\u003c\/li\u003e\n\u003cli\u003eCheck that operating ambient temperatures inside the local junction box stay strictly within the -40 to 70 deg C thermal envelope.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52634891878696,"sku":"FC-GMLA16","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/FC-GMLA16__1.jpg?v=1789977660","url":"https:\/\/www.powerdcs.com\/products\/honeywell-fc-gmla16-analog-input-fta-module","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
