MKS 651 Controller for Conductance Control Valves

Most often chosen for its features and value.

• Compatible with all MKS Instruments throttle valves and Baratron^® pressure transducers

Features

• Self-tuning control that automatically sets all factors
• New algorithm that gives fast, precise, repeatable pressure control
• RS-232, analog, or TTL interface for communicating with host systems
• Adjustable soft-start that opens valve slowly to reduce turbulence
• Two relays to indicate out-of-limits conditions
• MTBF analysis and STRIFE-test to ensure a robust, reliable design
• All controls are easily programmed from the front panel or remotely through RS-232, TTL, or analog voltage
• Local/remote override is by a front panel key switch
• LCD readout shows valve position and displays pressure in units of torr, mtorr, mbar, cmH₂O, in H₂O, μbar, kPa, or Pascal
• Five re-programmable set-points provide pressure or position control
• Local, and remote, selectable open, close, and stop functions enable system setup and diagnostics
