The rack frame hosts redundant I\/O module pairs connected via an integrated backplane bus, delivering hot-standby redundancy to ensure uninterrupted signal transmission during primary card failures. Operating across an ambient temperature envelope of -20 to +55 deg C, the 8.5 kg chassis provides electrical distribution and mechanical support for up to 8 input\/output channels across safety-critical control 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-0003R\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\u003e8.5 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e177 mm x 482.6 mm x 280 mm\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\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\u003ePower Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eRedundant I\/O Chassis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRedundancy Architecture\u003c\/td\u003e\n\u003ctd\u003eHot Standby\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Capacity\u003c\/td\u003e\n\u003ctd\u003eSupports 8 input\/output channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Range\u003c\/td\u003e\n\u003ctd\u003e0-20 mA \/ 4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal Range\u003c\/td\u003e\n\u003ctd\u003e0-20 mA \/ 4-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBus Communication\u003c\/td\u003e\n\u003ctd\u003eModbus RTU protocol support\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCertifications\u003c\/td\u003e\n\u003ctd\u003eCE, TUV, UL508, CSA\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-0003R incorporates backplane galvanic isolation barriers and noise suppression routing across all 8 I\/O channel paths. The internal bus decoupling protects internal processor communication against field-side electrical surges, cross-talk, and ground loop potentials. Designed to support standard 0-20 mA and 4-20 mA current loops, the backplane maintains signal fidelity for digital process variables and 4-20 mA HART loop protocol telemetry, preventing transient faults on one branch from propagating to secondary redundant cards or primary controllers.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the hot-standby redundancy mechanism operate within the FC-IOCHAS-0003R frame?\u003c\/p\u003e\n\u003cp\u003eA: The chassis backplane actively routes dual power and signal paths to primary and secondary I\/O module slots, enabling immediate fault-over transfer without interrupting active control signals.\u003c\/p\u003e\n\u003cp\u003eQ: What physical mounting standards apply to the FC-IOCHAS-0003R chassis assembly?\u003c\/p\u003e\n\u003cp\u003eA: With overall dimensions of 177 mm x 482.6 mm x 280 mm, the enclosure aligns with standard 19-inch industrial rack cabinets using designated side-flange retention points.\u003c\/p\u003e\n\u003cp\u003eQ: What compliance certifications govern the electrical safety of this chassis?\u003c\/p\u003e\n\u003cp\u003eA: The chassis is certified under CE, TUV, UL508, and CSA standards for installation in industrial automation environments.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the 8.5 kg chassis into a standard 19-inch enclosure frame, securing all four corner mounting flange bolts to structural cabinet rails.\u003c\/li\u003e\n\u003cli\u003eConnect dual 24 VDC feed wires to primary and secondary power terminals to establish redundant backplane power distribution.\u003c\/li\u003e\n\u003cli\u003eRoute field I\/O cabling through cable managers, keeping low-voltage 0-20 mA and 4-20 mA signal wires isolated from AC power lines.\u003c\/li\u003e\n\u003cli\u003eAttach all cable shields directly to the cabinet main ground bar using low-impedance grounding clamps to prevent noise interference.\u003c\/li\u003e\n\u003cli\u003eVerify that cabinet ambient temperature stays within -20 to +55 deg C and relative humidity remains below 95% non-condensing prior to energizing system loops.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":52641884143912,"sku":"FC-IOCHAS-0003R","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.png?v=1789982412","url":"https:\/\/www.powerdcs.com\/products\/fc-iochas-0003r-honeywell-redundant-i-o-chassis","provider":"Power DCS Parts Limited","version":"1.0","type":"link"}
