GE DS200ACNAG1A ARCNET LAN Connection Board
Product Description:
The GE DS200ACNAG1A is an ARCNET LAN Connections Board designed for GE’s Mark V Turbine Control System and compatible with EX2000 drive systems. As a compact, externally mounted PCB, it serves as a critical interface for ARCNET data links, connecting the main controller, IOS, protection module, and Mark V turbine control panel via coaxial cables—each board can terminate two coaxial cables using its two female BNC plugs, with the ARCPL connector exclusive to ARCNET models.
Key hardware includes four metal film resistors, two transistors, one diode, three capacitors, two communications relays, a six-pin male vertical pin terminal connector, and two metal-ringed ground openings on either side. It operates at 2.5 Mbps, resulting in ~400 ns signal network time—a timing constraint that limits ARCNET system length to four miles to avoid timeouts.
Its part number encodes key details: the “A” suffix denotes an A-rated functional revision, and “G1” indicates a normal-style protective PCB coating for hardware durability. It supports input voltages for Exciter Field Ground Detector Alarm, Malfunction, and Diode Fault signals, and handles up to four 4-20 mA outputs via configurable digital-to-analog converters on the NTB/3TB board. Most applications leverage the Status_S data link, and its external placement and simple component layout enable easy installation and removal.
Key Features:
ARCNET Data Link Core: Enables reliable communication between critical Mark V component via coaxial cable termination.
Compact & Accessible Design: Externally mounted with a simple component layout, facilitating quick installation, removal, and maintenance.
Defined Performance Metrics: Operates at 2.5 Mbps with a 4-mile system length limit, ensuring consistent data transmission.
Protective & Revision Coding: “G1” group designation ensures durable PCB coating; “A” revision tag signals functional updates for optimized performance.
Versatile I/O Support: Handles specific fault/ alarm input voltages and up to four 4-20 mA outputs, integrating with NTB/3TB boards for configurable signal conversion.
