Product manual:

TEL Tokyo Electron 381-642277-1 restriction board
Category: Limiter Board
Manufacturer: Tokyo Electron Ltd. (TEL)

1、 Product Function Overview
This restriction board is an auxiliary circuit module in TEL semiconductor equipment system, and its main functions usually include:

Limit, protect, or regulate input voltage, current, or signal amplitude

Prevent signal overload, protect downstream circuits or precision components

Provide filtering, clamping, or voltage stabilization control within a specific signal range

Trigger protection mechanisms or alarm functions in case of device abnormalities or boundary states

2、 Typical application areas
This module is typically applied in the following systems to protect critical components or stabilize signal quality:

1. Gas control system
Limit pressure/flow sensor signal fluctuations to ensure valve control circuit stability

Prevent sudden signal disturbances from affecting precise gas supply

2. Power supply and drive control system
Overvoltage/undervoltage protection for voltage/current control signals

Limit the impulse current or reverse voltage at the moment of motor start-up

3. I/O interface and communication system
Limiting external input signals to prevent signal abnormalities from causing damage to the control system

Improve the anti-interference ability of the system

4. Safety interlock circuit
Restricting or interrupting power supply or executing commands in hazardous conditions

Realize the judgment of "limiting conditions" in the interlocking triggering logic

3、 Technical characteristics (speculation)
Multi channel signal input with clamp or voltage stabilization function

Capable of processing analog or digital signals

Equipped with signal isolation, surge protection, and status indication

Used in conjunction with the main control board, relay board, and power module
