Fig. 10 CURRENT TRANSFORMER INPUT WIRING
This input allows you to measure and display the current running
in the load, driven by a time proportional control output, during
the ON and OFF periods of the output cycle time. By this feature
it is also available the "Output failure detection" function (see
page 66).
