The VSM10 Voltage Sensing Module (option
K51
) allows
the line supply or motor voltage characteristic to be
precisely sensed.
The VSM10 is used, for example, to switch to a rotating
synchronous motor (flying restart function).
Design
The VSM10 Voltage Sensing Module has the following
interfaces:
• 1 connection for direct voltage sensing up to 690 V
• 1 connection for voltage sensing using voltage
transformers, max.100 V 3 ph.
• 2 analog inputs (reserved for resonance monitoring in
Active Interface Modules)
• 1 temperature sensor input (KTY84-130 or PTC)
The status of the VSM10 Voltage Sensing Module is
indicated by a two-color LED.
