C A
This module together with the "MP" input board, performs the signal input conditioner
(see Fig. 2). This module contains the trimmers and jumpers for the amplifier gain and
the low level output (offset).
The signal input connections are made at Terminals 3, 4, 5 and 6.
Each signal type use some of these terminals.

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.
