Designed to manage RS-485 network physical layers, the module accepts an operating voltage of 120 VAC at 60 Hz with a continuous current rating of 10 A. The unit is housed in an IP65 enclosure measuring 94 mm x 140 mm x 89 mm, processing differential RS-485 communication lines to execute multi-drop node synchronization across industrial controller backplanes.\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\u003e51202325-100\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\u003e0.50 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e94 mm x 140 mm x 89 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\u003e120 VAC, 60 Hz, 10 A current rating\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eRS-485 serial interface\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIngress Protection\u003c\/td\u003e\n\u003ctd\u003eIP65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temp\u003c\/td\u003e\n\u003ctd\u003e-55 to +85 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Platform\u003c\/td\u003e\n\u003ctd\u003eHoneywell C300 \/ Series C Systems\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003e4-20 mA HART Loop Protocol \u0026amp; Channel-to-Channel Isolation\u003c\/h3\u003e\n\u003cp\u003eThe 51202335-100 incorporates optoelectronic line isolation between the high-power 120 VAC main supply rails and low-voltage RS-485 communication differential transceivers. When installed alongside analog instrument buses processing 4-20 mA HART loop protocol signals, the internal shielding suppresses common-mode voltage spikes and high-frequency noise. This isolation scheme preserves channel-to-channel isolation parameters and prevents ground potential differences across field cable runs from disturbing serial controller data transmission.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the RS-485 communication lines be connected or disconnected while the 120 VAC supply is active?\u003c\/p\u003e\n\u003cp\u003eA: High-voltage wiring must be completely isolated before servicing terminals; however, the optically isolated RS-485 communication channels can be reconfigured if proper ground potential equalization is maintained.\u003c\/p\u003e\n\u003cp\u003eQ: What termination impedance is required for the RS-485 bus managed by this cable controller?\u003c\/p\u003e\n\u003cp\u003eA: Standard 120 ohm line-termination resistors should be applied at the physical end nodes of the RS-485 differential pair to prevent signal reflection across high-speed data runs.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eMount the IP65 enclosure securely onto the cabinet DIN-rail or mounting plate using the provided hardware points.\u003c\/li\u003e\n\u003cli\u003eConnect 120 VAC power leads to the designated power terminals, ensuring line, neutral, and frame earth conductors are wired correctly.\u003c\/li\u003e\n\u003cli\u003eTerminate RS-485 differential data cables using shielded twisted-pair conductors, bonding the cable shield braid to cabinet ground at a single point.\u003c\/li\u003e\n\u003cli\u003eRoute high-voltage AC lines in separate wireways from RS-485 data paths to maintain signal fidelity and minimize noise coupling.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53626046710069,"sku":"51202335-100","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/51202335-100_Cocoai.png?v=1790057347","url":"https:\/\/www.5gplc.com\/products\/honeywell-51202335-100-series-c-communication-cable-controller","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
