Product Short Description
Product Name: Analog Input Electronic Module (Tokyo Electron)
Product Overview:
The TEL 381-642664-1 is an analog input signal conditioning and acquisition module used inside Tokyo Electron semiconductor process equipment. It collects analog process signals, converts them to digital data, and transmits them to the tool’s main controller.
Description
Technical Specifications:
-
Manufacturer: Tokyo Electron (TEL)
-
Model: 381-642664-1
-
Module Type: Analog input electronic module
-
Supported Signal Types: 0–10 V, 4–20 mA, RTD, thermocouple
-
Conversion: Analog-to-Digital via onboard ADC
-
Isolation: Electrical isolation to prevent noise and ground-loop interference
-
Communication: Data link to main process controller (PLC / process computing unit)
Key Features:
-
Multi-signal-type compatibility (voltage, current, RTD, TC)
-
Signal isolation for noise immunity
-
Real-time conversion for closed-loop process control
-
Designed for the electrical and thermal environment inside TEL tools
Application Scenarios:
-
Lithography pre-/post-processing platforms – reads heater platen temperature, chemical flow, ambient pressure
-
CVD/PVD deposition chambers – monitors chamber temperature, reactant gas flow, coolant ΔT
-
Etch equipment – measures in-chamber temperature, current, voltage, gas density
-
Wafer-handling systems – acquires pneumatic pressure and motor feedback current
Installation & Usage Notes:
-
Module is an internal spare part; installation must follow TEL service manuals.
-
Correctly match thermocouple type or RTD curve in firmware to avoid scaling errors.
-
Maintain isolation barriers; do not bypass ground-isolation features.
-
Handle as an ESD-sensitive assembly.
