Engineered for Mark V Speedtronic Signal Acquisition

This board collects diverse input signals from multiple turbine sources. It provides centralized data acquisition for the GE DS200PCCAG1A DS200PCCAG1ACB module. You will find this unit exclusively in the Mark V turbine control series. Unlike standard input boards, this version uses the “ACB” functional revision. It handles up to 24 discrete and analog input channels simultaneously.

Technical Specifications & Physical Dimensions

We designed this control input board for comprehensive signal monitoring. The table below presents all verified technical specifications.

Functional Architecture and Channel Configuration

This input board connects to field sensors across the turbine system. It uses 24 optocouplers for complete electrical isolation. You can configure each channel for discrete or analog signals. Moreover, the module includes six 12-bit analog-to-digital converters. These components digitize analog signals with 0.1% accuracy. Consequently, the board provides clean data to the main processor.

Installation and Operational Guidelines

The GE DS200PCCAG1A DS200PCCAG1ACB scans all inputs every 4 milliseconds. It updates the backplane buffer after each complete scan cycle. You must verify signal types before wiring any channel. Always use twisted-pair cables for analog inputs. This practice reduces common-mode noise interference significantly. Furthermore, the board supports software-configurable input thresholds. This feature adapts to different field device output ranges.

Physical Characteristics and Environmental Limits

This input board has a rugged, conformal-coated PCB construction. Its substantial 0.48 kg weight reflects the multi-channel design quality. The layout follows GE’s standard Mark V clearance specifications. Therefore, it mounts securely inside C-frame or G-frame cabinets. The board includes LED status indicators for each active channel. In addition, it maintains stable operation between -25°C and 60°C ambient temperature. You can store this unit safely up to 85°C.
