It interfaces field transmitters with the SAI-1620m safe high-density analog input module, converting 0(4)-20 mA field-current signals into voltage signals for input processing. It also distributes power to passive transmitters, limits transmitter-loop current, and monitors the external supply.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe FC-TSAI-1620M provides the field wiring interface for analog signals used in safety-related and non-safety-related applications. Its 16 input channels are arranged in two groups of eight, with a common 0 V connection within each group.\u003c\/p\u003e\n\u003cp\u003eEach channel uses a precision input resistor to convert the incoming field current into a voltage signal for the associated SAI-1620m module. The assembly therefore performs signal conditioning and field termination rather than the analog-to-digital conversion performed by the input electronics.\u003c\/p\u003e\n\u003ch3\u003eTransmitter Connections and Signal Conditioning\u003c\/h3\u003e\n\u003cp\u003eThe FTA supports 0-20 mA and 4-20 mA current-loop signals. Active transmitters can supply their own loop current, while passive transmitters require power distribution through the FTA.\u003c\/p\u003e\n\u003cp\u003eFor passive transmitter connections, the assembly provides a 30 V DC external supply path with voltage and current limitation. External power is not required when all connected inputs use active transmitters. When passive transmitters are used, the external supply must be available for the associated input loops.\u003c\/p\u003e\n\u003ch3\u003eTechnical 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-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\u003eAnalog Input Field Termination Assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem\u003c\/td\u003e\n\u003ctd\u003eSafety 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\u003eChannel Arrangement\u003c\/td\u003e\n\u003ctd\u003e2 groups of 8 channels, common 0 V per group\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003e0-20 mA \/ 4-20 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\u003e250 Ohm ( +\/- 1%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Power Supply\u003c\/td\u003e\n\u003ctd\u003e30 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Supply Current\u003c\/td\u003e\n\u003ctd\u003e3 mA, excluding input loop loads\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage 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\u003e0.10%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePassive Transmitter Output Resistance\u003c\/td\u003e\n\u003ctd\u003e270 Ohm ( +\/- 5%)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIgniting Current per Channel\u003c\/td\u003e\n\u003ctd\u003eLess than 120 mA at 30 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFuse Rating\u003c\/td\u003e\n\u003ctd\u003e315 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Output Current per Fuse\u003c\/td\u003e\n\u003ctd\u003e220 mA\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\u003eFuse AC Voltage Rating\u003c\/td\u003e\n\u003ctd\u003e125 V\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\u003eSystem Connection and Installation\u003c\/h3\u003e\n\u003cp\u003eThe FC-TSAI-1620M connects to the SAI-1620m through the SICC-0001\/Lx system interconnection cable, which plugs into the FTA's SIC connector.
