MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200ACNAG1A DS200ACNAG1ABB connection turbine control board interfaces between field sensors and the Mark V controller. This board conditions and converts analog signals from critical turbine measurements. You will find this connection board in Speedtronic Mark V turbine cabinets. Its reliable design ensures accurate signal transmission for control algorithms.
Analog Interface Architecture
This connection board provides eight analog input channels for process variables. Consequently, it reads speed, temperature, and pressure sensors simultaneously. The GE DS200ACNAG1A DS200ACNAG1ABB also includes four analog output channels. Moreover, a 16-bit ADC delivers high measurement resolution. You can configure each channel independently via software jumpers.

Signal Conditioning and Output Drive
The unit includes programmable low-pass filters on each input channel. Therefore, it rejects high-frequency noise from industrial environments. This board replaces the DS200ACNAG1ABB version without any calibration changes. Simply remove the old board and install this one. GE designed this connection 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 DS200ACNAG1A DS200ACNAG1ABB includes a precision voltage reference for self-calibration. Accordingly, it maintains accuracy over temperature and time. This feature ensures stable readings for turbine control loops.
Calibration and Installation Guide
You must perform an auto-calibration routine after installing this board. The onboard reference provides 2.5V and 5V for gain verification. The GE DS200ACNAG1A DS200ACNAG1ABB 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 DS200ACNAG1A DS200ACNAG1ABB works with all GE Mark V control systems. Proper grounding of analog commons prevents ground loop errors. This board operates reliably in non-condensing environments only.
