The module rack chassis hosts redundant I\/O cards connected via an integrated backplane bus, delivering hot standby redundancy to prevent system shutdown during module faults. Operating across an ambient temperature range of -20 to +55 deg C, the 5.6 kg chassis manages power distribution and signal switching for up to 8 channels handling 0-20 mA and 4-20 mA current loops.\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-IOCHAS-0003S\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\u003e5.6 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e34.0 cm x 18.8 cm x 6.5 cm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +55 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003eInput: 5 VDC, max 2.56 A per slot; Output: 24 VDC, max 2 A for up to 54 slots\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eRedundant I\/O Module Chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 8 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSignal Compatibility\u003c\/td\u003e\n\u003ctd\u003e0-20 mA and 4-20 mA current loops\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Protocol\u003c\/td\u003e\n\u003ctd\u003eMODBUS RTU, Ethernet router service\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHumidity Range\u003c\/td\u003e\n\u003ctd\u003e5% to 95% RH (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eSafety Manager \/ Experion PKS DCS\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 HART Loop Integration\u003c\/h3\u003e\n\u003cp\u003eThe FC-IOCHAS-0003S incorporates channel-to-channel isolation architecture across its backplane channels to decouple individual I\/O loops from main processing logic. The internal power routing bus delivers regulated 24 VDC to connected active field devices while maintaining signal fidelity for standard 0-20 mA and 4-20 mA HART loop protocol instruments. Backplane suppression circuitry eliminates ground loops and limits transient voltage spikes, preventing field noise from corrupting MODBUS RTU bus communication or safety processor telemetry.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: What are the primary input and output electrical power ratings for the FC-IOCHAS-0003S chassis backplane?\u003c\/p\u003e\n\u003cp\u003eA: The backplane accepts an input logic power of 5 VDC at a maximum of 2.56 A per slot, while supplying 24 VDC field power at a maximum of 2 A across up to 54 slots.\u003c\/p\u003e\n\u003cp\u003eQ: How does hot standby redundancy function within the FC-IOCHAS-0003S rack assembly?\u003c\/p\u003e\n\u003cp\u003eA: Dual redundant backplane paths continuously mirror signal inputs and execution states between paired I\/O modules, enabling instantaneous transfer without interrupting loop execution during a single module failure.\u003c\/p\u003e\n\u003cp\u003eQ: What current signal formats can be routed through the chassis I\/O channels?\u003c\/p\u003e\n\u003cp\u003eA: The channels support standard industrial analog signal ranges including both 0-20 mA and 4-20 mA current loops.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the chassis inside a grounded instrument rack, securing all mounting screws to the cabinet enclosure frame.\u003c\/li\u003e\n\u003cli\u003eTerminate the 5 VDC backplane logic feeds and 24 VDC power lines according to terminal block polarity schematics.\u003c\/li\u003e\n\u003cli\u003eRoute 0-20 mA and 4-20 mA signal cables in shielded twisted-pair configurations, keeping them separated from AC power lines.\u003c\/li\u003e\n\u003cli\u003eAttach all signal cable shielding directly to the primary cabinet ground bus bar using low-impedance grounding clamps.\u003c\/li\u003e\n\u003cli\u003eConfirm that ambient operational temperatures within the cabinet remain between -20 and +55 deg C prior to placing redundant loops into active service.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52642434220328,"sku":"FC-IOCHAS-0003S","price":315.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0827\/6266\/2184\/files\/FC-IOCHAS-0003R-removebg-preview_44ce9e50-5567-453b-ade6-bf46ee098bc0.png?v=1789982557","url":"https:\/\/www.powerdcs.com\/products\/honeywell-redundant-i-o-chassis-fc-iochas-0003s","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
