Type PR4000B
DIGITAL POWER SUPPLY AND READOUTThe Type PR4000B is a RoHS-compliant Digital Power Supply and Display module. It
is available with either one or two channels, and has a 4.5 place backlit LCD display asstandard. Both versions support internal or external set points and master/slave control
schemes. The single-channel version can control one Baratron® pressure transducer or
one Mass-Flo® meter or controller. The dual-channel version supports up to two pressuretransducers or two mass flow controllers, or one of each.
Engineering units are user-selectable as Torr, mTorr, kTorr, Pa, kPa, cmH2O, psi, N/qm, µbar,mbar and bar for pressure transducers; sccm, scm, slm, scfm, scfh for flow meters 		
or controllers and V, % and °C.

Features & Benefits• Fully software & hardware compatible to 		PR4000A• Versatile 4½-place digital LCD display/		power supply unit for use with most MKS 		
general purpose Baratron® pressure 		transducers and Mass-Flo® controllers 		
(see ordering information)• Digital RS-232 interface standard; RS-485
interface optional on two-channel models• User-selectable engineering units for 		both pressure transducers and flow 		
devices• Menu-driven with simple set-up and 		operation• Two fully adjustable relay outputs for limit
monitoring• Analog input/output with 16-bit resolution• Half 19-inch rack mount or table top• Auto zero capability• 1.5 Amp high power output for 		temperature controlled manometers• CE and RoHS (Restriction of Hazardous
Substances) compliant
