Features:
- Supports simplex, dual, and TMR architectures for integration into different GE Mark VIe control system configurations.
- Provides 24 discrete I/O points through removable barrier-type terminal blocks for organized industrial wiring connections.
- Supports DIN-rail or surface mounting and operates across a wide temperature range in hazardous certified environments.
The General Electric IS200TDBTH2ACD is a discrete I/O terminal board developed for GE Mark VIe turbine control systems. The module serves as a field interface between external devices and the associated I/O processor pack, allowing discrete status signals and control outputs to be transferred within the system. With support for 24 discrete points, the board is suitable for industrial monitoring and switching operations that require stable signal management. The removable terminal arrangement also helps simplify field wiring installation and maintenance procedures. IS200TDBTH2ACD is commonly integrated into structured turbine control cabinets where organized signal routing is important.
IS200TDBTH2ACD is designed for compatibility with IS220PDIO packs and supports simplex, dual, and TMR redundancy structures. This allows the terminal board to be applied in different system layouts depending on operational requirements and control architecture design. The board operates with a 24 Vdc input supply and supports up to 0.81 A current capacity during operation. The T-type terminal layout includes removable 24-point barrier terminal blocks that support 12 AWG wiring and 300 V insulation ratings. These characteristics support reliable field connection management in industrial automation environments.
The General Electric IS200TDBTH2ACD also provides flexible installation capability through DIN-rail and surface mounting methods. The module is designed for operation in industrial environments with temperatures ranging from -30°C to +65°C. Hazardous area approval for the terminal board and connected I/O package supports installation in certified industrial locations requiring compliant equipment. Within gas turbine and steam turbine systems, IS200TDBTH2ACD is used for discrete signal transmission, field device interfacing, and control signal distribution. The module forms part of the broader GE Mark VIe platform used in modern industrial process and turbine control systems.
The IS200TDBTH2ACD General Electric Terminal Board may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Onboard Identification: This board is equipped with an onboard ID chip containing information such as serial number, board type, and version number. The controller reads this chip to ensure hardware compatibility and prevent configuration errors.
- Status Feedback: In the Mark VIe system, it provides real-time feedback to the controller on the status of 12 Form-C relay outputs, facilitating system monitoring of output execution and rapid fault location.
- Signal Consistency Verification: When used in TMR (Triple Modular Redundancy) configuration, the controller continuously compares input data from three PDIO I/O packages, automatically identifying and reporting abnormal signal channels through an internal voting algorithm.
- Loop Monitoring: In conjunction with the host computer control software, it can diagnose the wetting voltage and loop integrity of 24 isolated contact inputs, ensuring reliable field sensor connections.
- Hazardous Environment Certification: This terminal board and its accompanying PDIO I/O packages are certified and approved for installation and use in hazardous locations with explosion risks.
- Noise Suppression: Built-in hardware filters and surge protection circuits at the input effectively shield against high-frequency noise and voltage surges in industrial environments, preventing false triggering that could affect system safety.
- Redundant Voting Architecture: Supports TMR mode, exchanging data through three independent I/O paths. Even if a single control path fails, the system can still maintain protection and control of critical equipment.
- Physical Isolation Protection: 24 contact inputs employ a grouped isolation design and possess 300V insulation strength, effectively preventing field wiring errors or ground potential interference from affecting the control core.
- Gas Turbine Auxiliary System Control: Utilizes its 12 relay outputs to control the start and stop of turbine auxiliary equipment (such as lubricating oil pumps and heaters) and receives feedback signals from limit switches.
- Emergency Shutdown Protection Logic: In a triple redundancy (TMR) configuration, as part of the trip logic, it receives signals from field emergency stop buttons or pressure switches to ensure safe fuel supply cutoff in extreme situations.
- Discrete Equipment Monitoring: Integrated into the Distributed Control System (DCS), it centrally monitors the status of valves, circuit breaker positions, and other switching information throughout the plant via 24 input channels.
- Control System Upgrade and Replacement: As a mature component of the Mark VI series, it is used for partial upgrades of control cabinets in older units, improving the reliability of digital signal processing without altering field cabling.
