It provides 16 analog input channels for 0-20 mA signals and interfaces field detector wiring with the SAI-1620m high-density analog input module. Its termination circuitry supports signal conditioning and field power distribution.\u003c\/p\u003e\n\u003ch3\u003eFunction and Signal Interface\u003c\/h3\u003e\n\u003cp\u003eThe FC-TSGAS-1624 provides the connection point between field-mounted gas or flame detectors and the Safety Manager analog input system. Each input channel receives a detector current signal and converts it into a voltage signal for acquisition by the SAI-1620m module.\u003c\/p\u003e\n\u003cp\u003eThe 16 channels share a common 0 V reference. The assembly also provides fused power distribution to the connected transmitters, with individual channel protection specified in the hardware documentation.\u003c\/p\u003e\n\u003ch3\u003eAnalog Input Conversion\u003c\/h3\u003e\n\u003cp\u003eEach channel uses a precision 500 ohm resistor to convert the detector current into a voltage signal for the SAI-1620m. The conversion range at the FTA output is 0-4 V DC, with a specified accuracy of 0.1%.\u003c\/p\u003e\n\u003cp\u003eThe assembly supports both active and passive transmitter wiring arrangements. Individual field cable shield terminals provide separate termination points for analog input cable screening.\u003c\/p\u003e\n\u003ch3\u003ePower Distribution and Protection\u003c\/h3\u003e\n\u003cp\u003eThe FC-TSGAS-1624 uses an external 24 V DC supply connected through screw terminals A and B. It distributes power to the field transmitters through individual 500 mAT fused circuits. The external supply voltage can also be monitored by the Safety Manager through the SAI-1620m.\u003c\/p\u003e\n\u003ch3\u003eParameter Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\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\u003eFC-TSGAS-1624\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\u003eGas \/ Flame Detector Field Termination Assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem\u003c\/td\u003e\n\u003ctd\u003eHoneywell Safety Manager\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Input Channels\u003c\/td\u003e\n\u003ctd\u003e16\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003e0-20 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Current Range\u003c\/td\u003e\n\u003ctd\u003e0-25 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Resistance\u003c\/td\u003e\n\u003ctd\u003e500 ohm (+\/- 5%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Reference\u003c\/td\u003e\n\u003ctd\u003eCommon 0 V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Power Supply\u003c\/td\u003e\n\u003ctd\u003e24 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e3 mA (without field loads)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput to SAI-1620m\u003c\/td\u003e\n\u003ctd\u003e0-4 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Accuracy\u003c\/td\u003e\n\u003ctd\u003e0.1%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChannel Fuse Rating\u003c\/td\u003e\n\u003ctd\u003e500 mAT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse Dimensions\u003c\/td\u003e\n\u003ctd\u003e5 x 20 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Interconnection\u003c\/td\u003e\n\u003ctd\u003eSICC-0001\/Lx\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Analog Input Module\u003c\/td\u003e\n\u003ctd\u003eSAI-1620m\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\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eTS32 \/ TS35 x 7.5 DIN rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Dimensions\u003c\/td\u003e\n\u003ctd\u003e225 x 70 x 60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUsed DIN Rail Length\u003c\/td\u003e\n\u003ctd\u003e226 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.52 kg \u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eWiring and Installation Requirements\u003c\/h3\u003e\n\u003cp\u003eThe assembly provides 16 groups of four screw terminals, numbered 1 to 64.
