Basic information positioning
Brand/Series: General Electric (GE) Mark VIe Turbine Control System
Module type: Thermocouple Input Module (TC module)
Hardware design and interface speculation

1. Appearance and structure
Size: Standard rack-mounted module, compatible with Mark VIe backplane (usually the same size as other IO modules, such as approximately 40mm in width and 1U in height).
Front panel
Status indicator lights: Power (PWR), Module Ready (RDY), Fault Alarm (ALM), channel status (such as the corresponding LED flashing when a certain channel fails).
Configuration button/dip switch: It may be used to select the type of thermocouple (such as J, K, T, E type) or channel filter parameters (confirmed in combination with the manual).
Back interface:
Bus interface: Communicate with the controller through the backplane (such as SERCOS bus).
Power interface: 24V DC power supply (may share power supply with other modules).
Signal terminal block: It is used to connect thermocouple sensors (usually terminal type or plug-in type interface, supporting anti-reverse connection design).

2. Channel characteristics
The number of channels: The IS200ECTBG1ADE is presumed to have 8 or 16 thermocouple inputs (for analog input modules of the same series, such as the IS200ETBAG1A, which has 16 channels, the thermocouple module may adopt a similar configuration).
Signal type: Supports multiple thermocouple types (such as K type, J type, T type, E type, R type, S type), which can be selected through software or hardware configuration.
Input range: Typical thermocouple signal range (e.g., K-type: -20mV to 50mV, corresponding temperature -200°C to 1372°C).
Isolation characteristics: Electrical isolation between channels (isolation voltage ≥500V AC), suppressing common-mode interference.

Vi. Precautions for Use
1. Wiring and installation
Thermocouple cable selection: Use the corresponding type of compensating wire (such as K-type thermocouple with KX-type compensating wire) to avoid signal attenuation or the introduction of interference.
Grounding requirements:
The sensor end of the thermocouple is single-point grounded, while the module end is floating (to avoid ground loop interference).
The metal casing of the module must be reliably grounded (grounding resistance ≤4Ω) to reduce electromagnetic noise.
Polarity confirmation: When wiring, pay attention to the positive and negative poles of the thermocouple (for example, for type K: the positive pole is red and the negative pole is blue). Reversing the connection will cause abnormal measurement values.
