GE IS200TBCIH1CCD Mark VI Contact Input Terminal Board (TBCI Series)

Product Description

The GE IS200TBCIH1CCD is a dedicated 24-channel contact input terminal board, purpose-built for the GE Speedtronic Mark VI turbine control system, a core component in gas and steam turbine automation. As a multi-layer PCB with surface-mount devices (SMDs) and removable termination blocks, it serves as the critical interface between field dry contacts (e.g., limit switches, safety interlocks, and status sensors) and the Mark VI I/O system. The board integrates noise suppression circuitry to shield against surges and high-frequency interference, ensuring stable signal transmission in harsh industrial environments. It operates on 125V DC excitation power, with 21 channels rated at 2.5 mA and 3 channels at 10 mA to accommodate external solid-state outputs, and features self-diagnostic functions for excitation voltage monitoring and fault detection. With compliance to industrial control standards and seamless integration with Mark VI controllers, it is ideal for turbine protection, sequence control, and status monitoring in power generation and heavy industry applications.

Key Functions

The IS200TBCIH1CCD delivers essential signal interface and protection for Mark VI systems: 24-channel dry contact input with barrier-type terminal blocks for organized field wiring and easy maintenance; Noise suppression circuitry to prevent signal distortion from surges and electromagnetic interference, safeguarding system reliability; 125V DC excitation for contact activation, with channel-specific current ratings (2.5 mA/10 mA) to match diverse field device requirements; Self-diagnostic capabilities for real-time monitoring of excitation voltage and channel faults, enabling quick troubleshooting; Removable termination blocks for fast replacement and reduced downtime during maintenance; Seamless integration with Mark VI I/O processors for accurate status data acquisition and control logic execution; NEMA Class G creepage and clearance design for enhanced electrical safety in industrial settings.

Application Scenarios

The IS200TBCIH1CCD is widely used in turbine control and industrial automation: Gas and steam turbine protection systems for monitoring safety interlocks, emergency stop circuits, and valve position switches; Power generation plants for status monitoring of generators, feed pumps, and auxiliary equipment; Petrochemical and refining facilities for sequence control of compressors, heaters, and process valves; Heavy industry applications requiring reliable dry contact signal acquisition in high-vibration and high-interference environments; Mark VI system upgrades and retrofits to replace legacy terminal boards and improve signal integrity and maintainability.
