VersaTRAK
Analog Outputs

The aforementioned VersaTRAK models have four 4-20 mA analog output signals. These
outputs are powered from a DC power source. The 24 VDC may come from an external DC
power source or from the VT-PS-024-01N power supply.

Analog Output

Wiring

Two screw terminals are provided for the DC power source. One terminal is provided for each
output signal. The DC (-) terminal is used for the return wire of each analog output circuit.
