I/O modules

Engineered for Mark V Speedtronic Bridge Communication

This board manages data exchange between multiple drive bridges. It serves as the central communication hub for the GE DS200MBHAG2A DS200MBHAG2AFC module. You will find this unit exclusively in the Mark V turbine control series. Unlike standard comm boards, this version uses the “AFC” functional revision. It ensures reliable signal routing across up to four bridge interfaces.

Technical Specifications & Physical Dimensions

We designed this communication board for high-speed data transfer. The table below presents all verified technical specifications.

Functional Architecture and Port Layout

This hub board connects directly to the drive backplane. It uses five serial ports for bridge-to-bridge communication. You can configure each port for different data protocols. Moreover, the module includes two optical isolators. These components prevent electrical noise from corrupting signals. Consequently, the board maintains clean data transmission under heavy loads.

Installation and Operational Guidelines

The GE DS200MBHAG2A DS200MBHAG2AFC operates at 50 MHz clock speed. It achieves a 98% data throughput rate during normal use. You must verify the firmware revision before installing this board. Always match the connector labels P1 through P5 correctly. This procedure prevents cross-talk between bridge channels. Furthermore, the board supports hot-swappable replacement. This feature minimizes system downtime during maintenance.

Physical Characteristics and Durability

This communication board has a compact, multi-layer PCB design. Its lightweight 0.28 kg structure allows for easy handling. The layout follows GE’s standard Mark V coating specifications. Therefore, it fits seamlessly into existing C-frame cabinets. The board also includes diagnostic LED indicators. In addition, it maintains stable operation between -25°C and 60°C. You can store the unit safely up to 85°C ambient temperature.
