5.1 PA Connector Pin Assignment
CAUTION!
The pyrometer housing is connected to the signal ground via a
0.1
F/50V capacitor. Isolate any unused wires in order to avoid
the display of erroneous data.
Power Requirement 24 V DC
The instrument works with an operating voltage of 24 V DC. The voltage
required for operation must be supplied by a separate power supply. This
power supply unit must conform to directive DIN IEC 61010.
The supply voltage is 135 mA for standard design, 150 mA for models
with laser sighting and 175 mA with camera. PA pyrometer is equipped
with inverse polarity protection. The output currents and voltages share
one ground connection via pin 8 of the connector.
