PULSES / SECOND
TABLE 2
Table 2 indicates all the standard available ranges for these models when the frequency output
must be in pulses per second.
Set the jumpers/solder pads to the position indicated in Table 2. The jumpers are located on the
"MS-55" output module.
If the frequency output range is modified follow the adjustment and calibration procedure for
each model.
50 % of the full cycle
The frequency output for each range is indicated : 0 to 2500/5000 for example.
This means that the minimum frequency output is 2500 Hz. and the maximum frequency output
is 5000 Hz. Any frequency within the low and high value, can be obtained using the trimmer P3
located on the "MS-55" output module.

TABLE 6
The minimum input span is the minimum
difference between the maximum and
minimum input for a full scale output.
*
Table 6 indicates two standard available ranges for the CCT-55-I and its electrical specifications.
Using the jumpers located on the "MP" input board and "ME" input module, 4 different ranges may
be selected ( see Table 7).
For other signal ranges, contact the engineering department for more information.
