Sensor Type Selection; Cct-05, Electrical Features (Specifications) - Omega CCT-05 Series User Manual

SENSOR TYPE SELECTION

This signal conditioner can connect to standard
sensors such as PNP, NPN, Namur or ac signals.
See the Connections Section.
The signal conditioner provides two excitation
voltages for the sensors, 24 Vdc for PNP or NPN
sensors and 8.2 Vdc for NAMUR sensors. Table 4
indicates which jumpers must be selected for each
type of sensor. The jumpers are located on the "MP"
input board. See Fig. 8.
