This module features 16 robust channels capable of processing both 115 V AC and 115 V DC inputs. By delivering 2 kV galvanic isolation, it eliminates ground loops and protects control systems from high-voltage transients. The hardware automatically down-converts 115 V field signals into 24 V DC signals for direct interface with the SDI-1624 safety input module, making it ideal for critical emergency shutdown (ESD) and burner management systems (BMS).\u003c\/p\u003e\n\n\u003ch2\u003eCore Technical Advantages\u003c\/h2\u003e\n\u003ch3\u003eAdvanced Galvanic Protection\u003c\/h3\u003e\n\u003cp\u003eHeavy-duty optical isolation guarantees a 2 kV barrier between field-side wiring and the internal system backplane, protecting sensitive logic from voltage surges.\u003c\/p\u003e\n\n\u003ch3\u003eDual AC\/DC Versatility\u003c\/h3\u003e\n\u003cp\u003eSensing circuitry accepts input frequencies from 40 Hz to 300 Hz for alternating current alongside direct current compatibility, simplifying plant standardization.\u003c\/p\u003e\n\n\u003ch3\u003eFail-Safe Signal Conditioning\u003c\/h3\u003e\n\u003cp\u003ePrecision internal thresholds enforce a definitive LOW state (U ≤ 15 V or I ≤ 1.2 mA) to prevent floating signals or leakage currents from causing false trips.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; margin: 15px 0;\"\u003e\n  \u003cthead\u003e\n    \u003ctr style=\"background-color: #f2f2f2; border-bottom: 2px solid #ddd;\"\u003e\n      \u003cth style=\"padding: 10px; text-align: left; border: 1px solid #ddd;\"\u003eParameter\u003c\/th\u003e\n      \u003cth style=\"padding: 10px; text-align: left; border: 1px solid #ddd;\"\u003eSpecification Details\u003c\/th\u003e\n    \u003c\/tr\u003e\n  \u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eHoneywell (Safety Manager)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eModel Type\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eFC-TSDI-16115 \/ FS-TSDI-16115\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eChannel Count\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e16 Input Channels\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eNominal Input Voltage\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e115 V AC \/ DC\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eInput Frequency Range\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003eDC or 40 Hz to 300 Hz\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eGalvanic Isolation\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e2 kV (Input to Output)\u003c\/td\u003e\n    \u003c\/tr\u003e\n    \u003ctr\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e\u003cstrong\u003eDimensions (L × W × H)\u003c\/strong\u003e\u003c\/td\u003e\n      \u003ctd style=\"padding: 10px; border: 1px solid #ddd;\"\u003e300 × 109 × 68 mm\u003c\/td\u003e\n    \u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eThermal Derating Matrix\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUp to 50°C (122°F):\u003c\/strong\u003e Full voltage tolerance of -15% to +30%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUp to 60°C (140°F):\u003c\/strong\u003e Reduced voltage tolerance of -15% to +10%\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUp to 70°C (158°F):\u003c\/strong\u003e Nominal voltage only (-15% to +0%)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eInstallation and Maintenance\u003c\/h2\u003e\n\u003ch3\u003eDIN Rail Mounting\u003c\/h3\u003e\n\u003cp\u003eSnap the module firmly onto standard TS32 or TS35 DIN EN rails.

If leakage stays above 1.2 mA or 15 V, installing a bleed resistor across the terminals pulls the line down.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":51884862865540,"sku":"FC-TSDI-16115","price":255.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/7454\/7844\/files\/FC-TSDI-16115-1.jpg?v=1779537343","url":"https:\/\/www.etowonauto.com\/ha\/products\/honeywell-fc-tsdi-16115-safe-digital-input-fta","provider":"Etowon Auto","version":"1.0","type":"link"}
