NORVI X-DI4 DATASHEET

Introduction #

The NORVI X-DI4 is an industrial-grade digital input expansion module designed to seamlessly integrate with the NORVI X Modular Controller. It provides four optically isolated and protected 24 V DC digital inputs, enabling reliable interfacing with sensors, switches, and other field devices used in industrial automation and monitoring systems.

The DI4 variant directly connects its inputs to the host CPU’s GPIO, offering high-speed signal capture suitable for PWM, pulse-train, and encoder inputs. Its design ensures noise immunity, galvanic isolation, and compatibility with both sourcing (PNP) and sinking (NPN) sensor types.

Product Features #

• 4 × Optically Isolated 24 V Digital Inputs
• Direct GPIO Link to Host CPU (for high-speed signal acquisition)
• Supports fast inputs such as PWM, pulse trains & encoders
• One common terminal for all four inputs
• DIN-rail mountable industrial enclosure
• Status indicators for each input

Applications #

• Industrial switch and sensor interfacing
• Counter and encoder signal reading
• Pulse input measurement and frequency monitoring
• Fast digital signal capture from machines or process lines
