Precision Signal Generation for Actuator Control
The FUJI NP1AY02-MR analog output module converts digital setpoints from the CPU into proportional analog signals. This module drives actuators, valves, and variable-speed drives with high accuracy and stability. Industrial processes demand precise analog control, and this unit delivers that performance reliably.
Output Specifications and Electrical Ratings
This analog output module provides two isolated output channels with 12-bit resolution and high linearity. Each channel delivers either 0 to 10 V voltage or 4 to 20 mA current signals. The outputs accept a load of up to 500 ohms for current mode and 2 kΩ for voltage mode. Furthermore, the module includes a built-in voltage reference for stable operation across temperature variations.

Output Ranges and Configuration
The FUJI NP1AY02-MR supports multiple output ranges to suit various actuator requirements. Users can configure each channel independently for voltage or current output. A DIP switch on the module selects the active range without software intervention. Moreover, the module includes an output hold feature that maintains the last value during CPU errors.
Signal Generation and Accuracy
This analog output module uses a 12-bit digital-to-analog converter with integrated reference voltage. The converter achieves a settling time of under 100 microseconds for step changes. The module performs automatic calibration during power-up to maintain accuracy. Additionally, the outputs include short-circuit protection that limits the current to 25 mA.
Physical Design and Installation Details
This analog output module features a compact 40 mm housing for space-efficient cabinet installations. The unit weighs approximately 0.18 kilograms, allowing straightforward mounting and removal. A 10-pin connector provides access to both output terminals and the shield connection. Use shielded, twisted-pair cables for all analog output connections.
Diagnostics and Status Monitoring
The FUJI NP1AY02-MR includes LED indicators for power, output status, and error conditions. The module detects overrange conditions and reports them to the CPU. An integrated watchdog timer monitors the communication link and sets outputs to a safe state if the link fails. The unit also stores diagnostic data for troubleshooting purposes.
