CCT-55-I : DC CURRENT INTEGRATOR

ELECTRICAL FEATURES

SIGNAL INPUT

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.

Reference	A	B
Input range	0 to 5 mAdc	0 to 50 mAdc
Min. input Span *	0.5 mAdc	5 mAdc
Impedance	20 Ω	20 Ω

TABLE 6

*The minimum input span is the minimum difference between the maximum and minimum input for a full scale output.
