P2P1
This module together with the "MP" input board, performs all the input signal conditioning (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 model may use some of these terminals, see the Connections Section.
Table 4 indicates all the standard available ranges for the CCT-55-V and its electrical
specifications. The position of the jumpers are indicated in Fig. 8.
For different signal ranges, contact the engineering department for more information.
