Operating on a 24 VDC nominal power supply, the module acquires 0\/4–20 mA signals from transmitters and converts them into low-voltage signals for high-density safety analog input cards. As a non-conformal coated assembly, it serves as the physical interface between field wiring and system control electronics in Safety Instrumented Systems (SIS).\u003c\/p\u003e\n\u003ch3\u003eSignal Conditioning and Transmitter Power Distribution\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eFS-TSAI-1620M\u003c\/strong\u003e routes 16 analog channels arranged into two isolated groups of 8 channels with shared 0 V reference lines. Each channel incorporates a high-precision 250 Ω resistor to perform linear direct conversion of 0–20 mA field current loop signals into 0–4 VDC levels suited for processing by system I\/O modules like the SAI-1620M. The assembly provides integrated power distribution and voltage-current limiting to pass-through transmitter connections, protecting field loops in Class I, Division 2 hazardous locations.\u003c\/p\u003e\n\u003ch3\u003eMounting and Field Termination Interface\u003c\/h3\u003e\n\u003cp\u003eDesigned for standard DIN rail mounting (TS32\/TS35), the module features screw terminal connections accepting field conductors up to 2.5 mm² (AWG 14). Dedicated ground terminals per channel allow proper cable shield grounding to reduce common-mode noise and maintain signal accuracy across sensitive safety loops.\u003c\/p\u003e\n\u003ch3\u003eTechnical 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-TSAI-1620M\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\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eSafe Analog Input Field Termination Assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eSafety Manager \/ Fail Safe Controller (FSC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e16 channels (2 groups of 8)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Supply Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC (24 to 30 VDC external range)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal Range\u003c\/td\u003e\n\u003ctd\u003e0 to 20 mA \/ 4 to 20 mA DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance\u003c\/td\u003e\n\u003ctd\u003e250 Ω (±1%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Signal to I\/O Module\u003c\/td\u003e\n\u003ctd\u003e0 to 4 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConversion Accuracy\u003c\/td\u003e\n\u003ctd\u003e±0.1%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to +70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e210 x 70 x 60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting Style\u003c\/td\u003e\n\u003ctd\u003eDIN rail (TS32 \/ TS35 x 7.5)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.99 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What is the main difference between the FS-TSAI-1620M and FC-TSAI-1620M modules?
