Process transmitter for DIN top hat rail mounting.
Dependent on the unit version the measured analogue
input signal is displayed on a 5 digit display. The
analogue output transmits the displayed value as either a
current or voltage. Two presettable alarm set points
monitor the measured input for infringements on the
preset conditions and also control the two output relays.
The analogue signal connected is digitalised, analysed
and indicated in the display. A digital/analogue convertor
creates a propotional current or voltage signal that is
available at the output terminals for additional peripheral
equipment.
icrocontroller controlled measurement system with LC
display, analogue input, analogue output, alarm set point
relays and loop power supply.
