Illustration 2.12 Terminal Numbers
•
Connector 1 provides four programmable digital
inputs terminals, two additional digital terminals
programmable as either input or output, a 24V DC
terminal supply voltage, and a common for
optional customer supplied 24V DC voltage. FC 302
and FC 301 (optional in A1 enclosure) also provide
a digital input for STO (Safe Torque Off) function.
•
Connector 2 terminals (+)68 and (-)69 are for an
RS-485 serial communications connection
•
Connector 3 provides two analog inputs, one
analog output, 10V DC supply voltage, and
commons for the inputs and output
•
Connector 4 is a USB port available for use with the
MCT 10 Set-up Software
•
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.
See 10.2 General Technical Data for terminal ratings details.
