The PCD45 is used for the display and further processing
of measured variables with signals available as voltage or
direct current. The display calibration is carried out with a
keypad on the front.
Two analog inputs enable the connection of two sensors.
Their information can be displayed with F1 and F2. The two
measured variables F1 and F2 are processed further in the
calculation block and displayed with F3.
The measured variables F1, F2 and F3 can be output as
separate analog output signals -10...+10 V/ 0...+10 V for
the direct control of processes.
Two adjustable limits on "P1" and "P2", with free
assignment, enable monitoring of production processes.
In addition, the PCD45 is equipped with an electronic
peak-value memory (slave pointer), which can be
programmed by the operator on F1, F2 or F3.

Hours and Time Meters
Detecting and displaying times
Typical Application Examples:
Hours and time meters are suitable for
– Recording of elapsed time
all production areas in which the
– Recording of machine running times
switch-on time of machines, devices
– Recording throughput times
and systems is monitored. For
– Time control
example, warranty times, maintenance
– Short-time measurement
intervals and operating costs can be
– Control of mixing times
determined, and throughput times or
– Furnace controllers
mixing times can be detected. The
– Service life measurement
electronic hours meters operate with
– Display of warranty times
quartz accuracy and, in contrast to
electromechanical solutions,
independently of the respective mains
frequency. The accuracy is 100 ppm.
Both hundredths of an hour and
minutes can be displayed.
