AMAT 0190-37684
Product Name
Public spare-part sources describe alternative configurations: controller/I-O PCB with MKS CDN494R architecture and pneumatic throttle valve for process chambers. Confirm the physical device, system platform, and BOM before use.
Controller/I-O PCB Variant
Product Name
Chamber analog/digital I-O and controller interface board.
Detailed content
Product Introduction
The PCB variant processes analog and digital signals for vacuum-chamber subsystems. Selected listings associate it with MKS AS02494/CDN494R architecture and AMAT gas/RF chassis applications.
Technical Specifications
- Manufacturer: Applied Materials in AMAT listings; MKS Instruments referenced in selected CDN494R listings
- Type: controller and I-O interface PCB
- Signal types: multi-channel analog input/output and discrete digital logic
- Power rails: +5 V and ±12 VDC from subrack backplane in selected listings
- Operating temperature: 0–50°C
- Indicators: onboard LEDs for power and communication health
- Form factor: 3U/subrack card-edge module in selected listings
Function Features
- Maps analog sensor data and digital status to chamber controller
- Supports gas, pressure, and RF subsystem signal handling
- Provides diagnostic LEDs for rail and communication status
- Integrates into multi-chamber control backplanes
Application Scenarios
- AMAT Centura/Producer chamber control
- Gas delivery, vacuum pressure, and RF interface loops
- Legacy semiconductor subrack I-O replacement
Material Composition
- Multilayer FR-4 control board
- Gold or industrial-grade edge connectors
- Analog isolation, digital logic, and LED components
Structural Characteristics
- Card-edge plug-in format
- High-density backplane connector
- Diagnostic LED array on board surface
Working Principle
Analog inputs are conditioned and digitized, digital lines are latched and isolated, and the result is passed over the backplane to the chamber controller. Output stages drive actuators, valves, or interface logic according to host commands.
Installation Requirements
- Verify backplane slot, voltage rails, and firmware revision
- Use ESD handling and cleanroom-approved storage
- Confirm MKS/AMAT cross-reference if CDN494R labeling is present
Usage Notes
- Do not install under power
- Validate analog ranges and digital addresses after replacement
- Inspect edge connector for contamination before insertion
