6.15.1.2. Control Inputs

These inputs allow the user to remotely initiate Zero and Span calibrations. Two methods for energizing the inputs is provided below; the first using the internal +5V available on the CONTROL IN connector and the second, if an external, isolated supply is employed.

U

DC power for Input

Input for +5 VDC required to activate inputs A - F. This voltage can be

Internal +5V Supply

Internal source of +5V which can be used to activate inputs when

connected to pin U.

 

 

 

There are two methods to activate control inputs. The internal +5V available from the “+” pin is the most convenient method (Figure 6-18). However, to ensure that these inputs are truly isolated, a separate, external 5 VDC power supply should be used.
