Overview
The DS200SIOBG1AAA is a printed circuit board developed by General Electric for the Mark V Turbine Control System Series. It functions as an SC2000 VME I/O board, delivering multi-input/output signal handling within the Mark V Series architecture. This model is an evolved version of the original DS200SIOBG1 parent board, incorporating three significant product revisions that distinguish it from the base design. Furthermore, it belongs specifically to the SC2000 subsystem of the Mark V product line.
Product Identification and Configuration
General Electric designates this board as an SC2000 VME I/O Board within the Mark V Turbine Control System Series. The DS200SIOBG1AAA is not the original PCB of this functionality; the DS200SIOBG1 serves as the parent model. Meanwhile, this specific variant carries three revisions denoted by the suffix characters, which modify the original design without altering the core I/O function. The board integrates on-board RAM to support real-time data buffering for connected field devices.

I/O Characteristics and Performance
This board provides 16 digital input channels, each accepting a 24 VDC signal. The I/O response time remains at or below 1 ms, enabling timely signal acquisition for turbine control loops. Furthermore, the on-board RAM works with the VME bus interface to maintain data integrity during high-speed scanning cycles. The 8 W power consumption rating allows operation from a 24 VDC supply with up to 20 percent voltage tolerance, which suits industrial environments where supply fluctuation occurs.
Environmental and Physical Properties
The DS200SIOBG1AAA operates reliably between 0 deg C and +60 deg C, while storage is possible from -25 deg C to +70 deg C. The physical dimensions measure 2 cm by 18.6 cm by 26.1 cm, and the unit weighs 0.38 kg. Therefore, maintenance personnel can anticipate standard VME rack space requirements when planning installation or replacement activities.
Compatibility and System Context
This board forms part of the SC2000 subsystem inside the Mark V Series. The Mark V Series itself represents one of the final General Electric control platforms to employ the patented Speedtronic control system technology first introduced with the Mark I Series in the late 1960s. However, the original documentation does not specify direct plug-in compatibility with other VME boards beyond the SC2000 subsystem context. For example, users should verify rack slot assignments against their specific Mark V system configuration before ordering.
Frequently Asked Questions
Q: What distinguishes the DS200SIOBG1AAA from the base DS200SIOBG1 board?
A: The DS200SIOBG1AAA incorporates three significant revisions to the original DS200SIOBG1 parent design. These revisions modify the board without changing its fundamental SC2000 VME I/O function, but the exact nature of each revision is not detailed in the available documentation.
Q: Can the DS200SIOBG1AAA operate with a 12 VDC power supply?
A: No. The board requires a 24 VDC power supply with a tolerance of plus or minus 20 percent. Therefore, the acceptable input range is 19.2 VDC to 28.8 VDC.
