Pressure transmitters
Programmable digital display
Type series AP
with 1 or 2 limit value switches for PT100, PT1000
and voltage and current signals
AP ...
Various routines for setting the following parameters
are integrated into the microprocessor-controlled
digital display:
· Measuring range (start and end point)
· Display range (start and end point)
· Setting of decimal point
· 2 limit values (relays) and their hysteresis
· Relay dropout or pickup delay
· Scanning of minimum and maximum
measured value
· Rounding up or down of last digit
· Averaging
Technical data
Input signals Freely selectable by
setting jumpers.

All routines and parameters can be set with keys on the front. The switching status of the relays is displayed
by LEDs. Setting is buffered. If the supply voltage is interrupted, the set parameters are
retained. For powering transmitters, an electrically isolated 24 VDC power supply (max. 30 mA) is
available.
