The GE DS200TCCBG8B DS200TCCBG8BED analog board handles precision signal processing for GE Mark V control systems. This board converts field sensor signals into digital data for the main controller. You will find this analog board in turbine control cabinets and drive panels. Its high-resolution design ensures accurate measurement of critical process variables.
Input Architecture and Signal Conversion
This analog board provides eight differential analog input channels. Consequently, it rejects common-mode noise from long field wiring. The GE DS200TCCBG8B DS200TCCBG8BED accepts both voltage and current input signals. Moreover, a 16-bit ADC delivers high measurement resolution. You can configure each channel independently via software jumpers.

Output Capability and Channel Management
The unit includes four analog output channels with 12-bit resolution. Therefore, it can drive actuators, valves, and recorders directly. This board replaces the DS200TCCBG8BED version without any calibration changes. Simply remove the old board and install this one. GE designed this analog board for single-slot installation. Hence, it fits directly into existing Mark V rack positions.
Six PCB layers separate analog and digital signal paths effectively. Three connectors handle all field wiring and backplane communication. The GE DS200TCCBG8B DS200TCCBG8BED also includes programmable filtering on each input channel. Accordingly, it rejects 50/60 Hz noise from industrial environments. This feature ensures stable readings from thermocouples and pressure transmitters.
Calibration and Field Wiring Guide
You must perform a factory calibration after installing this board. The onboard precision voltage reference ensures measurement consistency. The GE DS200TCCBG8B DS200TCCBG8BED stores calibration constants in non-volatile memory. Consequently, it retains settings even after power loss. Two status LEDs indicate board health and communication activity.
Always use shielded twisted-pair cable for analog input wiring. Connect the shield only at the board end for best noise rejection. The GE DS200TCCBG8B DS200TCCBG8BED works with all GE Mark V control systems. Proper grounding of the analog commons prevents ground loop errors. This board operates reliably in non-condensing environments only.
