Notes:
Overview of overload relays – matching contactors see
page 5/27.
Analog input modules, e.g. SM 331, must be configured for
4-wire measuring transducers. The analog input module may not
supply current to the analog output of the 3RB24 relay.
For current measuring modules and related connecting cables
see next page, "Accessories" see pages 5/31 and 5/32.
