20 HFG2.0 USER GUIDE
Analog Inputs
The analog input, DEMAND, has a current range of 4 - 20 mA. It is
electrically isolated up to 500 VAC from the enclosure, 120 VDC power,
digital I/O, and serial interface. The analog interfaces are not isolated from
each other. See Figure 1-13 for a typical analog input connection.

Analog Outputs
The analog outputs, MOTOR CURRENT and POSITION, have a current
range of 4 - 20 mA. They are electrically isolated up to 500 VAC from the
enclosure, 120 VDC power, digital I/O, and serial interface. The analog
interfaces are not isolated from each other. See Figure 1-14 for a typical
analog output connection.
