9. Technical data
General details
Unit function Process display for panel mounting
Application
Process
display, power
supply, alarm
contactor
The display receives an analogue signal and shows the
corresponding value on the display. The analogue output
transmits the displayed value as either a current of
voltage. Two presettable limit values monitor the
measured value for any infingement of the preset
conditions and control the two output relays. Transmitters
connected can be directly powered by the unit.
Operating and
system
construction
Measurement
principle
The analogue signal connected is digitalised, analysed
and indicated in the display. A digital/analogue convertor
makes a proportional current or voltage signal available
for additional peripheral equpment at the output terminals.
Measurement
system
Microcontroller controlled display with LED display,
analogue input, analogue output, limit alarm relays and
loop power supply.
