•
Connector 1 provides four programmable digital
inputs terminals, two additional digital terminals
programmable as either input or output, a 24 V
DC terminal supply voltage, and a common for
optional customer supplied 24 V DC voltage
•
Connector 2 terminals (+)68 and (-)69 are for an
RS-485 serial communications connection
•
Connector 3 provides two analog inputs, one
analog output, 10 V DC supply voltage, and
commons for the inputs and output
•
Connector 4 is a USB port available for use with
the frequency converter

MG16E202 - VLT® is a registered Danfoss trademark
Also provided are two Form C relay outputs that
are in various locations depending upon the
frequency converter configuration and size
Some options available for ordering with the unit
may provide additional terminals. See the manual
provided with the equipment option.
