Description

The IS200TBTCH1CBB functions as a specialized thermocouple terminal board engineered by GE Industrial Systems for integration within the EX2100 Excitation Control System Series. Acting as a rugged field termination layer, this board accepts and routes up to twenty-four unique thermocouple inputs to the downstream VTCC Thermocouple Processor Board assembly. The IS200TBTCH1CBB provides individual channel high-frequency noise suppression and localized cold junction reference processing parameters essential for maintaining precision temperature feedback loops across industrial power generation systems.

The board hosts pluggable, heavy-duty barrier terminal blocks to facilitate efficient field installation and hot-swappable maintenance without interrupting stable infrastructure wiring. For multi-channel redundancy architectures, the hardware is configured with six communication connector ports to establish parallel signal transmission pathways back to the main control module. The entire printed circuit board assembly is encapsulated with a resilient layer of conformal coating to guard against atmospheric degradation in harsh turbine and generator environments.

Features

• Multi-Channel Input Routing: Routes 24 independent field thermocouple input signals directly to the VTCC processing card framework.
• Cold Junction Compensation: Incorporates high-accuracy localized circuitry dedicated to real-time cold junction reference tracking and noise suppression.
• Pluggable Termination Blocks: Features two high-strength, screw-secured terminal blocks that accept up to two #12 AWG field conductors per point.
• Six-Port Connector Matrix: Engineered with six dedicated onboard communication connector sockets designated as JTA, JTB, JSA, JSB, JRA, and JRB.
• Conformal Environmental Protection: Sealed with a professional conformal circuit coating layer to mitigate moisture, dust, and particulate contamination.
• Visual Status Array: Equipped with three faceplate-mounted diagnosis LEDs to deliver instantaneous indications of normal operations or loop faults.

Applications

• EX2100 Excitation Control System automated thermal monitoring loops
• High-density thermocouple sensor routing and cold junction processing
• Fault-tolerant generator, exciter, and machinery temperature monitoring

Installation Guidelines

• Terminal Block Attachment: Secure the two pluggable terminal blocks to the base circuit card structure via the two factory-specified retention screws per block to ensure solid continuous contact.
• Field Wiring Integrity: Strip and insert field thermocouple leads into the terminal clamping slots, guaranteeing that the combined wiring layout does not exceed the maximum #12 AWG configuration or 300 V maximum threshold.
• Connector Port Assignment: Align and engage the interface ribbons into the JTA through JRB multi-pin socket matrix to synchronize clean dynamic voltage paths back to the central processing module.
