FUNCTIONAL DESCRIPTION:

IS200TBCAH2A is an RTD Input Termination Module manufactured and designed by General Electric as part of the Mark VIeS Series used in GE Distributed Turbine Control Systems. It is a device used to interface and terminate the connections of RTDs in a system. An RTD (Resistance Temperature Detector) is a type of temperature sensor that operates on the principle that the electrical resistance of certain materials changes with temperature. It provides accurate and reliable temperature measurements, making it widely used in various industries. The Termination Module RTD and 4ñ20 mA Input (TBCB) are in location seven of the R5 core. RTD and mA input signals are landed on the TBCB terminal board. Eight of the 4 -20 mA input signals have the option to be configured using hardware jumpers to be 0 -1 mA input signals. The signals connected to the TBCB terminal board are written to the TCCB board in the R5 core. It supports 2-wire, 3-wire, and 4-wire RTD configurations, providing precise temperature measurement over the full sensor range while performing linearization and low-pass filtering to condition the signal for accurate processing. The module provides full galvanic isolation between RTD inputs and control system logic, minimizing ground loops and maintaining signal integrity under high electromagnetic interference (EMI) conditions. It features diagnostics for detecting open-circuit, short-circuit, and out-of-range RTDs, with corresponding status flags communicated to the control system.

OPERATION:

The RTD input module is an intelligent block transfer module that interfaces analog input signals with any programmable controllers that have block transfer capability. Block transfer programming moves input data words from the module’s memory to a designated area in the processor data table in a single scan. It also moves configuration words from the processor data table to module memory. The input module is a single-slot module and requires no external power supply. After scanning the analog inputs, the input data is converted to a specified data type in a digital format to be transferred to the processor’s data table on request. The block transfer mode is disabled until this input scan is complete. Consequently, the minimum interval between block transfer reads (50ms) is the same as the total input update time for each analog input module.

FEATURES OF THE INPUT MODULE

The RTD input module senses up to 6 RTD signals at its inputs and converts them to corresponding temperature or resistance in 4–digit BCD or 16–bit binary format. Module features include:

• Six resistance temperature detector inputs
• Reports oC, oF, or ohms for 100 ohm platinum or 10 ohm copper sensors
• Reports ohms for other types of sensors
• Software configurable
• 0.1 degree/10 milliohm input resolution
• Auto–calibration open wire detection

The module can be configured for 100 ohm platinum or 10 ohm copper RTDs, or other sensor types such as 120 ohm nickel RTDs. Temperature ranges are available in degrees C or F. Values can also be measured in ohms. When using 10 ohm copper RTDs, it is necessary to dedicate your module for exclusive use with 10 ohm copper RTDs. You can configure the module to accept signals from any combination of 100 ohm platinum and other types of non–copper RTDs. Both cases are determined by block transfer write (BTW) selection.

FREQUENTLY ASKED QUESTIONS:

What is the IS200TBCAH2A?

It is an RTD Input Termination Module designed for GE Mark VIeS turbine control systems. It interfaces multiple Pt100 RTD sensors and converts their resistance signals into conditioned analog outputs (0–20 mA) for precise temperature measurement. The module performs linearization and low-pass filtering to ensure accurate readings. It also provides diagnostics for open-circuit, short-circuit, and out-of-range RTDs, with status flags communicated to the control system.

How many RTD channels does the module support?

The IS200TBCAH2A supports 8 RTD input channels, each configurable for 2-wire, 3-wire, or 4-wire RTD sensors. Input signals are individually conditioned and transmitted to the control system via analog outputs or block transfer. Jumper settings allow optional 0–1 mA input scaling.

What signal conditioning does the module provide?

The IS200TBCAH2A applies linearization of resistance to temperature values and low-pass filtering to remove high-frequency noise. Full galvanic isolation separates RTD inputs from control system logic, preventing ground loops and EMI interference. Conditioned signals are transmitted as 0–20 mA analog outputs or via digital block transfer to the processor.

How does it interface with the control system?

RTD and 4–20 mA signals are landed on the TBCB terminal board and transferred to the TCCB board in the R5 core using block transfer. Block transfer moves input data and configuration words between module memory and processor tables in a single scan. The module’s scan rate is 43 samples per second, and block transfer reads occur at a minimum interval of 50 ms.
