Alternative documentation (DS200ADGIG1AAA) describes this board as a 24 V DC Analog I/O PCB with 8 analog inputs and 8 analog outputs, 12-bit resolution, ±0.2% accuracy, operating from 24 V DC ±10% at 250 mA — confirm exact configuration against your system’s bill of materials.
Functional Features:
-
All 8 channels fully independently isolated
-
Each channel supports independent range configuration
-
Cold-junction compensation support for thermocouple inputs
-
Input signal quality diagnostics (open circuit, short circuit, over-range)
-
HART protocol support (selected configurations)
-
Comprehensive self-diagnostic functions for rapid fault localization
Material & Construction:
-
PCB: 6-layer FR-4 high-Tg substrate
-
ADC Chip: Industrial-grade 16-bit Σ-Δ A/D converter
-
Isolation Components: Magnetic isolation + capacitive isolation
-
Connector: 40-pin D-type connector + front-end wiring terminals
-
Housing: Galvanized steel shielded enclosure
Structural Features: Standard Mark VIe module dimensions (consistent with other DS200 series modules); front panel has 8 groups of channel status LEDs + fault LED; backplane has Genius Bus connector; front-end wiring terminals support spring-clamp connection.
Working Principle: Field analog signals enter the signal conditioning circuit (filtering, protection, cold-junction compensation) via front-end wiring terminals, are digitized by the 16-bit A/D converter, and the conversion results are uploaded to the Mark VIe controller via Genius Bus for engineering unit conversion and control calculation.
Application Scenarios: Gas turbine control (Mark VIe standard configuration), steam turbine control, oil refining DCS, power plant automation.
Installation Requirements:
-
Install in Mark VIe standard control cabinet rack
-
Signal lines must use double-shielded cable
-
Shield layer must be single-point grounded on the control cabinet side
-
Module address must be set via DIP switch or software
Usage Notes:
-
Thermocouple input requires confirmation that cold-junction compensation is enabled
-
Current input mode must not run with open circuit
-
Perform module self-diagnostic tests regularly
-
Module replacement requires module download and verification in the Mark VIe system
