20.14.1 Functionality
The Signal matrix for mA inputs (SMMI) function is used within the Application
Configuration Tool (ACT) in direct relation with the Signal Matrix Tool (SMT). See the
Application Manual for information about how milliamp (mA) inputs from external
transducers are physically connected to the MIM board inputs used in an IED. Via the
SMMI, the signals are brought into the IED configuration, for example, to the input for
ambient temperature compensation of the thermal overload function when there is a need
for ambient temperature compensation in the thermal function.
