Material Composition: 6-layer FR-4 high-Tg PCB with conformal coating; Industrial-grade 16-bit ADC (Analog Devices / TI); optocoupler + magnetic isolation devices.
Functional Features: Supports RTD (Pt100/Pt1000) and thermocouple (J/K/T/E/N/R/S/B) inputs (model-dependent); built-in sensor open-wire detection and over-range alarm; remote calibration (no on-board potentiometers); LED status indicators; hot-swappable (subject to controller support).
Working Principle: Field analog signals enter the module, are galvanically isolated, and digitized by the 16-bit A/D converter. The FPGA buffers and packets the data, then transmits it over Ethernet (UDP/IP) to the Mark VIe controller for processing.
Application Scenarios: Analog signal acquisition for gas turbines, steam turbines, generators, and balance-of-plant auxiliary systems in power generation.
Installation Requirements: Install inside a control cabinet (IP20 environment). Connect 24 VDC bus power and RJ45 Ethernet to the Mark VIe network. Observe correct polarity and shield grounding per Mark VIe wiring standards.
Usage Notes: Do not exceed 60 °C ambient. Verify channel configuration in the Mark VIe engineering tool matches the field wiring. Use only in cabinet environments with proper ventilation.
