The module 6ES5 464-8MC11 is suitable for connection of voltage sensors.
Wiring of the module (two-wire connection) is shown in the block diagram (on the first page of the
module description).
Start-Up of Module
Set the intended operating mode using the switch on the front panel of analog input modules 464-
8MC11. The switch is located on the right side at the top of the front panel of the module.
Power supply Set the switch to the available power supply frequency. This selects the inte-
frequency: gration time of the A/D converters for optimal interference voltage suppression.
Power frequency 50 Hz:
Power frequency 60 Hz:
Operation: Set the number of channels you wish to assign on the input module. If there
are fewer than four channels, the measured values will be updated faster.
Broken wire: Broken wire signalling not possible.
