Accepting up to 16 input channels across a 0 to 4.1 V range with an input resistance exceeding 1 MΩ, the unit utilizes an onboard 12-bit A\/D converter to digitize physical process variables. The module maintains absolute maximum signal limits of ±36 VDC with inter-channel cross-talk attenuation greater than 60 dB to prevent signal corruption during critical execution states.\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\u003eFS-SAI-1620M CC V1.4\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\u003e3 kg (Shipping Weight)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e4 HP, 3U (4 TE, 3 HE) rack spacing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temp\u003c\/td\u003e\n\u003ctd\u003e-20 to +60 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePower Consumption\u003c\/td\u003e\n\u003ctd\u003e5 VDC at 35 mA \/ 24 VDC at 35 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e16 safe analog input channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Range\u003c\/td\u003e\n\u003ctd\u003e0 to 4.1 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 1 MΩ\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eA\/D Converter\u003c\/td\u003e\n\u003ctd\u003e12-bit resolution (Inaccuracy: ±1 LSB)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Inaccuracy\u003c\/td\u003e\n\u003ctd\u003e\u0026lt; 0.25%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAbsolute Max Signal\u003c\/td\u003e\n\u003ctd\u003e±36 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Cross-Talk\u003c\/td\u003e\n\u003ctd\u003e\u0026gt; 60 dB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eApprovals\u003c\/td\u003e\n\u003ctd\u003eCE, TUV, UL, CSA, FM\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 FS-SAI-1620M CC V1.4 provides signal conditioning infrastructure that interfaces with field termination units converting 4-20 mA HART loop protocol transmitters into 0 to 4.1 V signal levels. Internal filtering logic coupled with high-impedance input stages guarantees channel-to-channel isolation, suppressing common-mode noise across shared 0 V reference lines. This input protection topology maintains high signal fidelity and prevents high-voltage fault surges on field loops from breaching internal 5 VDC and 24 VDC backplane supply rails.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the FS-SAI-1620M CC V1.4 be inserted into an active Safety Manager chassis without interrupting overall bus logic?\u003c\/p\u003e\n\u003cp\u003eA: Live replacement is supported on active backplanes provided the redundant controller chassis retains execution control and the extraction levers are disengaged straight out to prevent connector pin binding.\u003c\/p\u003e\n\u003cp\u003eQ: How does the module handle overvoltage condition events on individual signal lines?\u003c\/p\u003e\n\u003cp\u003eA: The input stages sustain absolute maximum input signals up to ±36 VDC without causing catastrophic physical failure or cross-channel breakdown to adjacent 12-bit conversion paths.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eSlide the 4 HP, 3U module card straight along the subrack guide rails until the backplane connectors seat firmly into the chassis interface.\u003c\/li\u003e\n\u003cli\u003eTighten the top and bottom front panel captive screws to lock the assembly in place and establish frame ground continuity.\u003c\/li\u003e\n\u003cli\u003eVerify that external 4-20 mA loop drop resistors on the associated field termination assembly are correctly scaled to output within the 0 to 4.1 V input window.\u003c\/li\u003e\n\u003cli\u003eRoute field signal cabling through dedicated, shielded wireways separated from high-voltage AC conductors and switching motor leads to maintain optimal noise rejection.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":53625515704629,"sku":"FS-SAI-1620M CC V1.4","price":66.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0973\/7630\/5461\/files\/FS-SAI-1620m_7ca44d44-f1c4-4e06-b444-74f280ad01be.png?v=1790049068","url":"https:\/\/www.5gplc.com\/products\/honeywell-fs-sai-1620m-cc-v1-4-safe-high-density-analog-input-module","provider":"High Five PLC Solution Limited","version":"1.0","type":"link"}
