FUJI NP1AY02 Analog Output Module

Board Overview

This analog output module converts digital commands into smooth analog signals. You can install FUJI NP1AY02 directly into any FUJI SPH series PLC rack. The unit provides two independent output channels with field-selectable ranges. It controls actuators, valves, and drives with high precision.

Board Layout and Components

The PCB places each output channel on separate circuit zones. Two precision DACs generate voltage references independently. Moreover, 128 discrete components include output buffers and protection diodes. Tantalum capacitors provide stable power for the analog circuits. Consequently, output signals remain steady under varying load conditions.

Installation Process

You can mount FUJI NP1AY02 into any standard SPH series rack slot. The backplane connector supplies power and receives digital data from the CPU. Furthermore, a front panel screw terminal block accepts field wiring for both channels. Clear labeling indicates voltage and current terminal assignments for each output.

Performance Advantages

This module converts each channel within just 1 millisecond. You can select voltage or current mode independently per channel. Therefore, one channel can drive a valve while the other controls a drive. The 14-bit resolution also provides smooth, step-free control signals.

Safety and Compliance

FUJI NP1AY02 meets CE and RoHS industrial standards. The board discharges stored energy below 3V within four seconds. Hence, technicians face minimal electrical risk during maintenance or replacement.
