Description
The IS220PTCCH1A is a thermocouple input module manufactured by General Electric as part of the Mark VIe distributed control system series. 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.
Functional Architecture and Processing
The 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.
Signal Processing and Compatibility
The 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.

Installation and Power Management
The 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.
Frequently Asked Questions
Q: How many thermocouple inputs can a single IS220PTCCH1A pack handle?A: A single pack supports up to 12 thermocouple input channels. Up to two packs can be combined to handle 24 inputs when using a TBTCH1C terminal board.
Q: Is it necessary to disconnect power before plugging in the power connector?A: No, power disconnection is not required because the I/O pack includes an intrinsic soft-start feature to control current inrush during power application.
Q: Which software is used to configure the module?A: The I/O pack is configured using the ToolboxST application.
