It connects the chassis earth level to -12 VDC referenced against the 0 VDC terminal of the primary 24 VDC power rail, detecting stray fault currents to prevent unintended grounding paths.\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\u003e10310\/3\/1\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\u003eStandard Safety Manager Module Mass\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003eStandard Safety Manager Enclosure Form Factor\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-40 deg C to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e24 VDC Supply Rail Feed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eEarth Leakage Detectors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eReference Circuit\u003c\/td\u003e\n\u003ctd\u003eEarth level connected to -12 VDC referenced to 0 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Modes\u003c\/td\u003e\n\u003ctd\u003eContinuous DC, 1 Hz Intermittent, 0.25 Hz Intermittent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStatus Visuals\u003c\/td\u003e\n\u003ctd\u003eGreen LED connection frequency indicator\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 Isolation Features\u003c\/h3\u003e\n\u003cp\u003eWithin safety-instrumented system (SIS) enclosures, ground faults can distort active analog instrumentation circuits. The 10310\/3\/1 module suppresses leakage loops affecting 4-20 mA HART loop protocol field devices by maintaining galvanic segregation across system power buses. By continuously measuring isolation performance without disturbing cold junction compensation (CJC) references or channel-to-channel isolation networks, the module preserves signal fidelity across critical process safety loops.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How do the selectable operating modes change the switching frequency on the 10310\/3\/1 hardware? A: The mode switch toggles between continuous \"DC\" monitoring and intermittent monitoring at either \"1 Hz\" or \"1\/4 Hz\" (0.25 Hz), altering the periodic sampling rate of the earth reference connection.\u003c\/p\u003e\n\u003cp\u003eQ: What does the green LED on the front panel indicate during operation? A: The green LED flashes in direct sync with the active sampling frequency (1 Hz or 0.25 Hz) when operating in intermittent monitoring modes to signal functional circuit switching.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eDe-energize the cabinet 24 VDC bus bar prior to inserting or removing the module from its backplane chassis location.\u003c\/li\u003e\n\u003cli\u003eEnsure the main system ground strap is securely bonded to the chassis rack earth terminal with low resistance (less than 1 ohm).\u003c\/li\u003e\n\u003cli\u003eSet the mode switch on the module front panel to the designated diagnostic position (DC, 1 Hz, or 1\/4 Hz) per system engineering specifications.\u003c\/li\u003e\n\u003cli\u003eRoute power supply feed lines and reference ground wiring in isolated conduit trays to minimize electromagnetic noise pickup.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":45431233052787,"sku":"10310\/3\/1","price":88.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/4348\/2227\/files\/10310_1200x1200_edf27a3b-cbb8-4ddd-bcae-3529a98e843c.jpg?v=1788231028","url":"https:\/\/www.dcssupplier.com\/products\/honeywell-10310-3-1-earth-leakage-detectors","provider":"DcsSupplier Limited","version":"1.0","type":"link"}
