Process display for panel mounting.
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.
The analogue signal connected is digitalised, analysed
and indicated in the display.
Microcontroller controlled display with LC display,
analogue input, limit relays and loop power supply.
Current, voltage, resistive thermometers (RTD),
thermocouple (TC).
