NX-series NX1P2 CPU Unit Hardware User’s Manual (W578)

The Analog I/O Option Board allows inputs from devices such a variable resistor controls and pro-

cess-control sensors. It also enables you to control inverters.

Analog inputs that can be processed are 0 to 10 V inputs from devices including a variable resistor, and

4 to 20 mA inputs from process-control sensors.

Analog outputs range from 0 to 10 V, which allow the CPU Unit to control inverters directly.

Refer to the NX-series NX1P2 CPU Unit Built-in I/O and Option Board User’s Manual (Cat. No. W579)

for details on how to use the Option Boards.
