8. PC operating software
An operating manual for the PC operating software can be
found on the programme installation medium.
9. Technical data
General details
Unit function Process transmitter for DIN top hat rail mounting.
Application
Process
transmitter
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.
Operation and
system
construction
Measurement
principle
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.
Measurement
system
Microcontroller controlled measurement system with LC
display, analogue input, analogue output, alarm set point
relays and loop power supply.
Input
Input types Voltage, current, resistive thermometer (RTD),
potentiometer (R), thermocouple (TC)
