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.
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.
Microcontroller controlled display with LED display,
analogue input, analogue output, limit alarm relays and
loop power supply.
