Technical Specifications Multi‑channel digital input and digital output channels, 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 anti‑corrosion treatment. Mark V plug‑in mechanical structure.
Functional Features Acquires multi‑group discrete digital status signals coming from field switches and auxiliary equipment. Completes signal level conversion and electrical isolation for field digital input signals. Converts digital commands from main CPU into field‑compatible digital output driving signals. Provides hardware over‑voltage protection for each I/O channel. Supports channel‑wise fault self‑diagnosis and status feedback to system.
Application Scenarios Spare replacement I/O interface board for GE Mark V gas and steam turbine control systems, used for power plant turbine control system maintenance and overhaul projects.
Performance Parameters Reliable digital signal isolation performance, stable input‑output level conversion accuracy, fast channel fault detection response speed.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Digital signal isolation components, level conversion chips, driving circuit devices, surge protection elements. Gold‑plated Mark V back‑plane edge connector.
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 includes status LED indicators and fixing screws. PCB layout separates field‑side signal circuit area and system‑side logic area to achieve electrical isolation effect.
Working Principle Board obtains operating power from Mark V chassis back‑plane. Digital control commands from main CPU go through isolation and driving circuit and output to field‑side equipment.
Installation Requirements Insert DS200SIOBH1ABA into corresponding chassis slot, tighten front‑panel fixing screws. Restore chassis power supply, complete system power‑on self‑test and digital input‑output channel loop verification.
Usage Notes Avoid mechanical scratch damage to conformal coating layer. Only apply within compatible GE Mark V turbine control chassis.
