Purpose

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.
