Technical Specifications Multi‑channel analog output interfaces, internal network signal transceiver circuit, Mark V back‑plane bus connector, auxiliary DC power supplied by chassis back‑plane. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, relative humidity 5%‑95% non‑condensing. Conformal coating PCB protection. Mark V plug‑in mechanical structure.
Functional Features Receives digital control set‑point commands from Mark V main CPU via back‑plane bus. Executes digital‑to‑analog conversion and generates stable analog output signals for field actuators. Implements internal network signal sending and receiving between system functional boards. Provides short‑circuit protection for each analog output channel. Supports hardware self‑diagnosis for output and network channels.
Performance Parameters Accurate digital‑to‑analog conversion precision, low analog output signal drift, stable internal network transceiver performance, reliable channel short‑circuit protection response.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Digital‑to‑analog conversion devices, analog driving components, network transceiver circuit chips, short‑circuit protection elements. Gold‑plated Mark V back‑plane edge connector. Front metal panel with status LED indicators and fixing hardware. Conformal protective coating layer.
Structural Characteristics Standard Mark V chassis plug‑in board dimension. Rear gold‑plated edge connector mates with Mark V back‑plane bus. Front metal panel mounts status LED indicators and fixing screws. PCB layout separates analog output circuit zone and digital network logic zone to suppress signal interference.
Working Principle Board obtains operating power from Mark V chassis back‑plane. Internal network transceiver circuit completes bidirectional data exchange between multiple functional modules inside control chassis. Hardware monitoring circuit detects output channel short‑circuit and network communication abnormal status.
Installation Requirements F Insert DS200NATOG2A into assigned chassis slot, tighten front‑panel fixing screws. Restore chassis power supply, complete system power‑on self‑test, analog output channel calibration and network communication verification.
Usage Notes Avoid mechanical scratch damage to conformal coating layer. Only apply within compatible GE Mark V turbine control chassis.
