PT100 Sender Input
75-240 ohm
resistance measuring
circuit
If PT100 sender is used, it must be
connected between this terminal and the
adjacent SGND terminal.
5
SGND (sender ground)
0 VDC
One terminal of the PT100 and other
temperature senders must be connected
here.
6
0-10V Analog Output
DC 0-10 V
Output resistance 1 k-
ohm
This output supplies 0-10VDC analog
voltage in order to control the frequency
inverter. The output is controlled by a PID
loop.
7
PRES+ (12V Pressure
sender Supply)
DC +12V output
70mA max.
The output supplies the positive to the 4-
20mA pressure senders.
8
Pressure Sender-3 Input
4-20mA inputs
The (-) terminal of the 4-20mA output
pressure senders is connected to this
terminal. The (+) terminal of the senders
must be connected to the PRES+ terminal.
