MeloAuto-Trusted PLC & DCS Parts Supplier
The GE DS200PCCAG1A DS200PCCAG1ACB RAM multi turbine control input board combines analog input and memory functions. This board reads sensor signals while storing critical control data. You will find this input board in Speedtronic Mark V turbine cabinets. Its integrated design saves rack space and simplifies system architecture.
Integrated Input and Memory Architecture
This control board provides sixteen analog input channels with 16-bit resolution. Consequently, it reads multiple turbine sensors from a single board. The GE DS200PCCAG1A DS200PCCAG1ACB also includes 32 MB of onboard SDRAM memory. Moreover, a dedicated processor manages both I/O and memory functions. You can configure each input channel independently via software.

High-Density Input and Memory Integration
The unit includes sixteen analog inputs for comprehensive turbine monitoring. Therefore, it measures pressures, temperatures, and speeds simultaneously. This board replaces the DS200PCCAG1ACB version without any configuration changes. Simply remove the old board and install this one. GE designed this input board for single-slot installation. Hence, it fits directly into existing Mark V rack positions.
Eight PCB layers separate analog, digital, and memory traces effectively. Four connectors handle all input, backplane, memory, and status signals. The GE DS200PCCAG1A DS200PCCAG1ACB stores calibration constants in onboard flash memory. Accordingly, it retains settings even after power loss. The onboard processor handles data buffering and signal conditioning locally.
Installation and Configuration Guide
You can configure analog input ranges individually through software. No jumpers or hardware changes are required for setup. The GE DS200PCCAG1A DS200PCCAG1ACB works with all GE Mark V turbine systems. Always use shielded cable for analog wiring longer than 10 meters. Proper grounding of analog commons prevents ground loop errors.
The onboard memory stores trend data and diagnostic logs. This data remains available even during main processor communication. The GE DS200PCCAG1A DS200PCCAG1ACB delivers reliable multi-channel input with onboard storage. Installation requires only a screwdriver for terminal connections. This board operates in non-condensing environments with adequate clearance.
