Integrated 10\/100 Mbps Ethernet and RS-485\/RS-232 serial interfaces establish deterministic data throughput to higher-level DCS host networks while maintaining loop signal integrity. Hardware-level channel-to-channel isolation prevents field ground loops and electrical transients from degrading 4-20 mA HART loop protocol signals and high-density I\/O bus communications.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How does the non-volatile memory on the 900C72-0144-00 behave during a control rack power loss?\u003c\/p\u003e\n\u003cp\u003eA: Program code and execution state parameters are stored in non-volatile flash memory, retaining full configuration data without requiring battery backup during prolonged power outages.\u003c\/p\u003e\n\u003cp\u003eQ: What is the maximum physical I\/O expansion capability supported by a single 900C72-0144-00 CPU?\u003c\/p\u003e\n\u003cp\u003eA: The module directly manages and scans a total memory map of up to 480 I\/O points across connected local and expansion racks.\u003c\/p\u003e\n\u003cp\u003eQ: Which serial communication protocols are physically supported by the integrated interfaces?\u003c\/p\u003e\n\u003cp\u003eA: The CPU module incorporates dedicated RS-232 and RS-485 physical serial ports for point-to-point interface connections and multi-drop field device networks.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eVerify that the primary rack power feed is de-energized before mounting or removing the 900C72-0144-00 CPU module.\u003c\/li\u003e\n\u003cli\u003eAlign the module housing with the subrack guide slots and push firmly until the rear edge connector latches fully into the backplane.\u003c\/li\u003e\n\u003cli\u003eTerminate Ethernet communication cables using shielded RJ-45 connectors, grounding the cable shield braid to the main panel enclosure earth bus.\u003c\/li\u003e\n\u003cli\u003eWire the 24 VDC auxiliary power supply connections ensuring correct polarity and recommended wire gauge limits.\u003c\/li\u003e\n\u003cli\u003eMaintain a minimum 50 mm clearance around the module chassis top and bottom vents to facilitate natural thermal convection.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53517238599989,"sku":"900C72-0144-00","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/900C72-0144-00_Cocoai.png?v=1788925345","url":"https:\/\/www.5gplc.com\/products\/hc900-honeywell-900c72-0144-00-c70-cpu-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
