Technical Specifications Power Supply: 5V DC, 24V DC Operating Temperature: 0℃ ~ 55℃ Mounting: VME rack card slot Signal Interface: Multi-channel analog input, digital I/O, rack bus Humidity: 20% ~ 80% non-condensing
Functional Features High-speed sampling of multi-channel analog sensor signals. Digital signal conversion and process parameter calculation. Two-way data communication with system main controller. Fault judgment and safety interlock output function. Built-in self-test function for circuit channel inspection. LED indicators for power and fault alarm state.
Application Scenarios Semiconductor plasma etch and thin film deposition equipment control cabinet. Process chamber temperature and pressure monitoring system. Gas delivery pipeline safety interlock control. Wafer transfer equipment signal acquisition subsystem. Applied Materials Centura platform maintenance spare board.
Material Composition PCB Substrate: High Tg flame retardant printed circuit board Electronic Components: Industrial grade integrated circuits and passive components Connector: Gold plated edge connector for rack backplane
Structural Characteristics VME standard size plug-in circuit board. Surface mounted electronic components on PCB surface. Gold plated edge connector for power and data exchange. Front panel equipped with fixing screw and status LED indicators. Anti-vibration structure for continuous cabinet operation.
Working Principle The board receives analog signals from pressure and temperature sensors, converts analog quantity to digital data and uploads data to host controller. It compares measured value with preset threshold and triggers safety interlock signal when parameters exceed safe range.
Installation Requirements Carry out electrostatic protection before handling the board. Cut off rack power before installation and removal. Align board with guide rail and insert fully to engage backplane connector. Tighten front panel fixing screw. Power on and run system self-test to verify each channel function.
