8. Technical data
General
information
Unit function Process display for panel mounting.
Application Process display,
limit contactor
The display recieves an anlogue signal and shows the
corresponding value on the display.
Four presettable set points monitor the measured
value for any infringement of the preset conditions and
control the 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.
Measurement
system
Microcontroller controlled display with LC display,
analogue input, limit relays and loop power supply.
Input Input types Current, voltage, resistive thermometers (RTD),
thermocouple (TC).
