It serves as the primary communications interface between a main HC900 controller and remote I\/O racks, routing field inputs and control outputs across distributed rack locations.\u003c\/p\u003e\n\u003ch3\u003eSystem Architecture and Expansion Capability\u003c\/h3\u003e\n\u003cp\u003eThe module mounts exclusively into the dedicated far-left slot of an HC900 remote I\/O rack. Depending on the host controller CPU model (C50, C70, or C75), a single system can support up to 11 remote expansion racks. Dual RJ-45 100Base-T Ethernet ports enable redundant cable topology, providing fault-tolerant communication links up to 100 meters using standard Category 5 twisted-pair cabling.\u003c\/p\u003e\n\u003ch3\u003ePower Requirements and Hot Swap Features\u003c\/h3\u003e\n\u003cp\u003eOperating on a 5 VDC internal bus supply, the module draws a maximum input current of 520 mA with a total power consumption of approximately 2.6 W. Live insertion and removal (hot swapping) are supported, allowing plant technicians to replace the module during active operation without disrupting field devices connected across other system racks.\u003c\/p\u003e\n\u003ch3\u003eEnvironmental Design and Safety Standards\u003c\/h3\u003e\n\u003cp\u003eEngineered for harsh industrial environments, the module features G3-level conformal coating for enhanced resistance against corrosive atmospheric contaminants and moisture. It operates reliably across a temperature range of 0 deg C to 60 deg C (10% to 90% non-condensing relative humidity) and complies with CE mark and EN 61326-1 industrial EMC standards.\u003c\/p\u003e\n\u003cfigure\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\u003e900SP1-0300\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\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eExpansion Processor Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Function\u003c\/td\u003e\n\u003ctd\u003eConnects HC900 controller to remote I\/O racks\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Slot\u003c\/td\u003e\n\u003ctd\u003eFar-left dedicated slot on remote I\/O rack\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Current\u003c\/td\u003e\n\u003ctd\u003e520 mA maximum at 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e~2.6 W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHot Swapping\u003c\/td\u003e\n\u003ctd\u003eSupported (live insertion and removal)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExpansion Capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 11 remote racks per host system\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunications Ports\u003c\/td\u003e\n\u003ctd\u003e2x RJ-45 Ethernet ports (100Base-T)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Distance\u003c\/td\u003e\n\u003ctd\u003eUp to 100 meters (Cat 5 cable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConformal Coating\u003c\/td\u003e\n\u003ctd\u003eClass G3 harsh environment protection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 deg C to 60 deg C (32 deg F to 140 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to 85 deg C (-40 deg F to 185 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e10% to 90% non-condensing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompliance \u0026amp; Approvals\u003c\/td\u003e\n\u003ctd\u003eCE mark, EN 61326-1 industrial EMC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the primary purpose of the Honeywell 900SP1-0300 module?
