The GE DS200ACNAG1A DS200ACNAG1ADD resource computer network board combines analog I/O with network connectivity. This board provides both signal processing and communication functions for Mark V systems. You will find this resource board in Speedtronic Mark V turbine cabinets. Its integrated design reduces the number of required boards.
Integrated Resource Architecture
This network resource board features eight analog input channels with 16-bit resolution. Consequently, it reads turbine sensors while communicating with plant networks. The GE DS200ACNAG1A DS200ACNAG1ADD also includes four analog output channels. Moreover, dual Ethernet ports provide network redundancy. You can configure each analog channel independently through software.

Analog and Network Integration
The unit includes both high-precision analog I/O and network connectivity. Therefore, it serves as a complete data acquisition and communication node. This board replaces the DS200ACNAG1ADD version without any configuration changes. Simply remove the old board and install this one. GE designed this resource board for single-slot installation. Hence, it fits directly into existing Mark V rack positions.
Eight PCB layers separate analog, digital, and network traces effectively. Four connectors handle all analog, Ethernet, and power signals. The GE DS200ACNAG1A DS200ACNAG1ADD includes programmable filters on analog inputs. Accordingly, it rejects noise before converting sensor signals. Five status LEDs provide complete operational feedback.
Network and Installation Guide
You can configure analog input ranges individually through software. The board supports both Modbus TCP and GE SRTP protocols. The GE DS200ACNAG1A DS200ACNAG1ADD works with all GE Mark V control systems. Always use shielded Cat5e or Cat6 cable for Ethernet connections. Proper grounding of cable shields ensures noise-free communication.
The onboard processor handles protocol conversion and data buffering. This offloads network tasks from the main turbine controller. The GE DS200ACNAG1A DS200ACNAG1ADD delivers reliable resource networking for turbine systems. Installation requires only a screwdriver for analog and power connections. This board operates in non-condensing environments with adequate ventilation.
