LAM 810-800256-004 | Node Board

Core functionality

This is a distributed I/O node controller for the machine, equivalent to the MCU motherboard of the local subsystem of the machine:

Collect analog signals (pressure, temperature, flow rate) from chambers and gas cabinets+digital DI/DO switch signals

Local logical operations, interlocking judgments, uploading status and alarms to the upper computer (VTM host)

Output control signals to drive solenoid valves and relays, responsible for local control of air circuits, water cooling, and safety circuits

Onboard firmware, storing the process I/O mapping and alarm threshold of the node, is a distributed control core board for the 2300 platform

Electrical core parameters

Power supply: DC+24V, low voltage DC power supply inside the machine

Main control: onboard dedicated MCU+program Flash+RAM, running independently locally, can maintain basic safety interlock by disconnecting the upper computer

signal channel

Multi channel DI digital input: sensor, door interlock, dry contact status

Multi channel DO digital output: relay/optocoupler isolated output, driving solenoid valve, indicator light

Multi channel analog acquisition: 4-20mA/0-10V pressure and temperature transmitter signals

Backplane bus: dedicated parallel backplane interface, connected to VTM backplane, and communicates with other node boards

Isolation protection: Optocoupler isolates the digital channel; Analog input with EMI filtering and TVS surge protection; Onboard fuse

PCB: FR4 multi-layer board, conformal coating, three proof coating, Fab cleanroom anti plasma RF interference

Physical and environmental parameters

Appearance: Standard VTM backplane plug-in PCB board, with gold fingers on the board edge and two sets of large European connectors on the top and bottom

Weight: Approximately 0.15kg

Working temperature: 10~40 ℃ (wafer Fab cleanroom)

Storage temperature: -20~+70 ℃

Humidity: 5% -80%, no condensation

Environment: High EMI plasma chamber surrounding environment, high requirements for RF anti-interference
