Answer Posted / mohammed abbas
INSTRUMENTS ARE DESIGN TO WORK ON LOW VOLTAGE BY THE
MANUFACTURER LIKE,YOKOGAWA,HONEYWELL AND ROSEMOUNT.LOW DC
VOLTAGE 24 VDC WHICH IS COMPITIBLE FOR ALL THE CONTOL
SYSYTEM AND THE FIELD INSTRUMENT WHICH IS DESIGN WILL WORK
ON 24 VDC WHICH IS REQUIRE TO ENERGIES THE ELECTRONIC PART
ALSO.IF WE USE 230VAC MEANS IT IS DANGER BECAUSE WHICH WILL
CAUSE A ACCIDENT OF LIFE ALSO IF ANY UNSKILLED TECHICIAN
WORK ON THAT INSTRUMENT.24 VDC IS SAFE FOR HUMAN BEING AS
WELL AS LOW POWER CONSUME,WHICH IS COMPITBLE FOR ALL THE
CONTROL SYSTEM AND ALL THE INSTRUMENTS IS BUILD WITH
ELCTROIC WHICH IS FUNCTIONING ON LOW 12 TO 32VDC.ALL THE
INSTRUMENT DESIGN IS ON THE BASIS OF LOW VOLTAGE AND LOW
CURRENT ONLY.
