- Page 9 1.3.1 Voltage transducer iMT406 The iMT406 voltage transducer is used for a permanent monitoring of a single-phase voltage value. PLCs, PCs, microprocessor control, indicators, alarms units etc. can be operated by the output signal. Voltage input can be connected either directly to low-voltage network or shall be connected to network via a corresponding voltage transformer (with standard 100 V output).
