is option is used in applications where isolation is
quired between an external control signal and the
otor controller (which may or may not be at earth
ound potential). It can be utilized to isolate a variety
voltage or current signals (see specifications below).
may also be used simply to isolate the speed
justment pot, and the pot power supply is included.
is option can be mounted in the enclosure or in a
ece of plastic track (included with kit).
