I/O modules

The DS200UCIAG2A DS200UCIAG2ACC acts as the primary logic board for the Mark V series. This unit processes all turbine control data through a dedicated microprocessor. It manages communications between the VME rack and external I/O networks. Consequently, you will need this motherboard for reliable legacy system operation.

Technical Specifications

We engineered this board for continuous duty in harsh industrial environments. Its compact form factor fits directly into a standard VME chassis. Additionally, the design includes a battery-backed memory for critical data retention.

Connector Layout and Signal Interface

The DS200UCIAG2A DS200UCIAG2ACC features a 50-pin ribbon connector for transducer signals. This port links directly to the TCSA termination board for signal conditioning. Two 3-pin headers provide auxiliary power for external sensors as well. A female 8-pin circular socket accepts peripheral cable connections for expanded I/O. Ten onboard LEDs give you instant visual feedback for each core function.

Energy Storage and Data Integrity

This motherboard uses a lithium cell for SRAM energy storage during shutdowns. This battery maintains critical logic states for over 8000 hours. Therefore, your control parameters remain completely intact without continuous external power.

Installation Guidance

Mount the DS200UCIAG2A DS200UCIAG2ACC using four corner screws into a VME rack cabinet. Always route circular cables away from high-voltage AC lines to reduce electrical noise. This board operates as the R Core motherboard in GE’s original Speedtronic architecture.
