PR4000 Display/Power Supply

The PR4000 display can operate one or two of any current

600-series Baratron capacitance manometers, including the

high-temperature 631D. Its LCD display screen is easy to

read, and it also offers two (2) independently-adjustable trip

relays for external device control. Its standard outputs are

high-resolution (16-bit) analog output and RS232C digital, and

it can be equipped with RS485 digital communications. It can

also remotely zero the 629F manometer equipped with that

option.

For customers who do not wish to arrange for their own delivery of electrical power to their Baratron capacitance

manometer(s), MKS offers four (4) different displays and power supplies that can be used with most of the products

described above. The descriptions below give a basic idea of the different models and their attributes.

660C Single-Channel

Display/Power Supply

The 660C is a microprocessor-controller single-channel

power supply and display that is designed for use with

all unheated and 45°C heated Baratron capacitance

manometers. It offers a 4.5-place digital display of the

Baratron capacitance manometer’s measured pressure, and

has a single-menu structure for easy setup and configuration.

It also offers four (4) open collector alarm trip points for

control of external devices. It can be equipped with an

RS232C digital interface, and it mounts in a compact 1/8 DIN

package.

PDR2000 Dual-Channel

Power Supply/Display

The PDR2000 is a low-cost two-channel power supply/display

capable of supporting most 600-series Baratron capacitance

manometers. It offers a very compact size (1/8 DIN package),

two (2) independently-adjustable relay trip points for external

device operation, and selectable engineering units. It also can

be ordered with an optional RS232C digital interface, and has

the ability to scale to non-standard pressure ranges.

CV7600 Isolation Systems

The MKS CV7600 Isolation System is designed to auto-

matically maintain a heated 600 series Baratron capacitance

manometer at vacuum throughout a process cycle. The

Isolation System consists of either a 627F or 628F heated

process Baratron capacitance manometer, an MKS

Pneumatic Isolation Valve, and an R750B mini-Baratron

capacitance manometer and Relay Module. The R750B

Relay Module monitors the process pressure, and provides

a contact closure that is used to open or close a (customer-

supplied) isolation valve in the pneumatic line to the MKS

Pneumatic Isolation Valve. This solenoid closes the MKS

valve whenever the process pressure exceeds the Full Scale

range of the 600-series Baratron capacitance manometer,

maintaining it in its optimum working range. Many different

Baratron capacitance manometer configurations and trip point

options are available; please contact the MKS Applications

group or your MKS Account Manager for more information.
