# NORVI X-Q4 – DATASHEET

The **NORVI X-Q4** is a 4 x Transistor Outputs Expansion module designed for the NORVI X modular controller platform.

It provides four high-side switching channels suitable for driving industrial actuators, relays, and solenoids. The outputs are optically isolated for circuit protection and utilize high-side MOSFET switches, enabling reliable control of DC loads with integrated fuse protection for industrial safety.

## Product Features

- 4 × Transistor Output channels
- High-side switching (up to 24V DC)
- Full optical isolation for circuit protection
- Integrated fuse and surge protection per channel
- Individual LED status indicators
- Designed for NORVI X modular architecture

## Applications

- Industrial actuator and valve control
- Driving DC relays and contactors
- Tower light and alarm signal management
- Modular PLC Output Expansion
- Factory automation and solenoid switching
- Remote device power triggering
