Engineered for Mark V Speedtronic Discrete Signal Control
This board handles all digital input and output signals for the drive. It provides reliable discrete control for the GE DS200TCDAH1B DS200TCDAH1BHD module. You will find this unit exclusively in the Mark V turbine control series. Unlike standard I/O boards, this version uses the “BHD” functional revision. It manages up to 24 independent digital channels for field devices.
Technical Specifications & Physical Dimensions
We designed this control board for flexible digital signal processing. The table below presents all verified technical specifications.

Functional Architecture and Channel Configuration
This control board connects field switches to the main processor. It uses 12 opto-isolated inputs for noise immunity. You can configure each input for sink or source wiring. Moreover, the module includes 12 sealed relay outputs. These components switch external loads without back-EMF damage. Consequently, the board handles both dry contacts and powered sensors reliably.
Installation and Operational Guidelines
The GE DS200TCDAH1B DS200TCDAH1BHD scans all inputs within 5 milliseconds. It updates outputs synchronously with the drive cycle. You must verify the voltage rating before connecting any input. Always use flyback diodes on inductive output loads. This practice prevents relay contact welding from voltage spikes. Furthermore, the board supports both normally open and normally closed configurations. This feature matches various field device safety requirements.
Physical Characteristics and Environmental Limits
This I/O board has a rugged, flame-retardant PCB construction. Its moderate 0.38 kg weight allows for easy field replacement. The layout follows GE’s standard Mark V clearance specifications. Therefore, it mounts securely inside C-frame or G-frame cabinets. The board includes LED indicators for each input and output channel. In addition, it maintains stable operation between -25°C and 60°C ambient temperature. You can store this unit safely up to 85°C.
