This I\/O pack provides the electrical interface between up to two Ethernet networks and a compatible thermocouple terminal board, supporting up to 12 thermocouple input channels with a 16-bit analog-to-digital converter.\u003c\/p\u003e\n\u003ch3\u003eFunctional Architecture and Processing\u003c\/h3\u003e\n\u003cp\u003eThe module features a two-board architecture consisting of a common processor board and a function-specific acquisition board for thermocouple signals. It is powered by an AMD-K6 300 MHz microprocessor, which manages signal conversion and internal diagnostics. Visual status indicators are provided via onboard LEDs, while local diagnostic communications are supported through an infrared port.\u003c\/p\u003e\n\u003ch3\u003eSignal Processing and Compatibility\u003c\/h3\u003e\n\u003cp\u003eThe module accepts inputs across types E, J, K, and S thermocouples within an input span of -8 mV to +45 mV. It accommodates diverse system configurations, allowing two packs to manage 24 inputs when paired with a TBTCH1C terminal board, or three packs in a triple modular redundancy setup using a TBTCH1B terminal board. Dual RJ45 Ethernet connectors enable connection to single or redundant control networks.\u003c\/p\u003e\n\u003cfigure\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\u003eIS220PTCCH1A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eGeneral Electric\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eMark VIe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Channels\u003c\/td\u003e\n\u003ctd\u003e12\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eThermocouple Types\u003c\/td\u003e\n\u003ctd\u003eE, J, K, S\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Span\u003c\/td\u003e\n\u003ctd\u003e-8 mV to +45 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eA\/D Converter\u003c\/td\u003e\n\u003ctd\u003e16-bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommon Mode Voltage\u003c\/td\u003e\n\u003ctd\u003e+5 Volts\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNormal Mode Rejection\u003c\/td\u003e\n\u003ctd\u003e250 mV\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMicroprocessor\u003c\/td\u003e\n\u003ctd\u003eAMD-K6 300 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-30 to 65 °C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInstruction Manual\u003c\/td\u003e\n\u003ctd\u003eGEH-6721\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation and Power Management\u003c\/h3\u003e\n\u003cp\u003eThe module mounts directly to the mating connector of the associated terminal board and is mechanically secured using threaded studs adjacent to the Ethernet ports. Power is supplied via a dedicated three-pin connector on the side of the pack. The unit incorporates an intrinsic soft-start feature that limits inrush current, allowing safe connection without powering down the supply cable. Initial configuration and parameter adjustments are performed using the ToolboxST application software.\u003c\/p\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: How many thermocouple inputs can a single IS220PTCCH1A pack handle?A: A single pack supports up to 12 thermocouple input channels.
