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.
