# NORVI X-AQ4 – DATASHEET

The **NORVI X-AQ4** is a high-performance 4-channel analog output expansion module for the NORVI X Modular Controller, enabling precise control of industrial actuators, VFDs, and process valves.

Featuring an onboard **STM32 microcontroller** for dedicated **12-bit DAC** management, the module offloads timing-critical signal generation from the main CPU to ensure superior stability. It provides four independent outputs configurable for **0-10V or 4-20mA** signals, each protected by **active filtering** and **TVS diodes** for maximum noise immunity and surge protection in harsh industrial environments.

## Product Features

- 4-Channel Analog Output
- 13-bit DAC Resolution
- 0-10V DC / 4-20mA Support
- I²C Expansion Bus
- DIP Switch Addressing
- Status LED indicators for each input channel
- Plug-and-play connection to NORVI X CPU module via expansion bus
- DIN-rail Mounting

## Applications

- Variable Frequency Drive (VFD) Control
- Process Automation Systems
- Analog Signal Simulation
- Remote Signal Transmission
- Lighting and Dimming Control
