Which 3 terminals are used for power supply common, or 0 volts?

_________

How many digital inputs are available?

_________

How many analog inputs are available?

_________

Which terminal is used for the analog output?

_________

For this lab, the switch box pictured below will simulate the SCADA signals. You will use

switches S1 - S6 to apply +24 VDC to the drives digital inputs for activation. You will use a

potentiometer located in the control the box and the drives’ o10 VDC supply to

create a signal that will range from 0-10 VDC. This analog voltage signal will act as the

reference signal sent from the SCADA system.

Use the banana plugs to make the connections shown below. Identify the terminals as you

make your connections to help familiarize yourself with the I/O terminals.

Ask your instructor

for help if you need assistance with this part.
