GE DS200SDCIG1A DS200SDCIG1AEB DC Power Supply

The GE DS200SDCIG1A DS200SDCIG1AEB DC power supply and instrumentation board combines power distribution with signal conditioning. This board provides regulated DC power while reading analog sensor signals. You will find this instrumentation board in Speedtronic Mark V turbine cabinets. Its integrated design reduces the number of required boards.

Integrated Power and Instrumentation Architecture

This instrumentation board features eight analog input channels with 16-bit resolution. Consequently, it reads pressure, temperature, and flow transmitters accurately. The GE DS200SDCIG1A DS200SDCIG1AEB also provides 24V DC power for field devices. Moreover, a built-in power supply eliminates external power modules. You can configure each input channel independently via software.

Power Supply and Signal Conditioning

The unit includes a built-in switching power supply for field devices. Therefore, you do not need external 24V DC power supplies. This board replaces the DS200SDCIG1AEB version without any calibration changes. Simply remove the old board and install this one. GE designed this instrumentation board for single-slot installation. Hence, it fits directly into existing Mark V rack positions.

Eight PCB layers separate power, analog, and digital sections effectively. Three connectors handle all analog input, DC output, and power signals. The GE DS200SDCIG1A DS200SDCIG1AEB includes programmable filters on each analog input. Accordingly, it rejects 50/60 Hz noise from industrial environments. Three status LEDs indicate power, activity, and fault conditions clearly.

Installation and Field Wiring Guide

You can configure analog input ranges individually through software. The onboard power supply can power up to eight field transmitters. The GE DS200SDCIG1A DS200SDCIG1AEB works with all GE Mark V control systems. Always use shielded cable for analog wiring longer than 10 meters. Proper grounding of analog commons prevents ground loop errors.

The power supply includes overcurrent and short circuit protection. This protection safeguards both the board and connected field devices. The GE DS200SDCIG1A DS200SDCIG1AEB delivers reliable DC power and instrumentation for turbine systems. Installation requires only a screwdriver for power and signal connections. This board operates in non-condensing environments with adequate clearance.
