NORVI Expansion Modules extend the functionality of industrial ESP32 controllers with reliable analog, digital, relay, and transistor I/O options. Designed for seamless integration, each module communicates via I²C or UART, allowing up to eight units to be daisy-chained for flexible system scaling. With features like optically isolated inputs, high-resolution ADCs and DACs, and robust relay switching, these modules deliver precision and durability for demanding industrial automation, data acquisition, and control applications.
Expand your controller with analog, digital, relay, or transistor I/O modules to connect sensors, actuators, and machines for automated process control.
Capture accurate sensor data with high-resolution analog input expansions (0-10V, 4-20mA, or differential signals) for monitoring temperature, pressure, flow, or other industrial parameters.
Drive control loops with analog output expansions for variable frequency drives (VFDs), valves, or proportional actuators, ensuring precise and stable operation.
Use digital input and transistor output modules for real-time status monitoring, fault detection, and alert systems in production equipment.
Pair expansions with LoRa, NB-IoT, or GSM modules to send collected data wirelessly to cloud platforms for analysis and predictive maintenance.
Relay and transistor outputs can control lighting, HVAC systems, and energy loads, while analog inputs track power, voltage, or current sensors.
High-resolution input/output modules are ideal for lab setups, prototypes, and industrial test benches requiring precise signal handling.
Mix and match expansion modules to create tailored controller solutions for your specific industry or product line, without redesigning hardware.
All modules connect directly to NORVI controllers through the dedicated expansion port — ensuring plug-and-play compatibility without complex wiring or additional power arrangements.
Start small and expand later — add more I/O or communication capabilities as your system grows, without redesigning your control cabinet.
Built with robust connectors, opto-isolation, and noise immunity, the modules ensure dependable performance even in harsh environments.
All modules are compatible with the Arduino IDE and ESP-IDF, making programming and integration straightforward for engineers, OEMs, and system integrators.
NORVI Expansion Modules are plug-in add-ons that extend the input, output, and communication capabilities of NORVI industrial controllers. They allow you to customize your controller for specific industrial or IoT applications.
Each module connects via a dedicated expansion port on the NORVI controller. Just plug the module into the port — no external wiring or power configuration is required.
NORVI offers a range of modules including:
Most expansion modules are compatible with NORVI IoT Controllers (ENET, RPI, and others) that feature the NORVI Expansion Port. Check your controller’s datasheet for compatibility.
No separate programming is required. Once connected, the module’s I/O or communication ports are accessible directly through the main controller using standard Arduino or ESP-IDF code.
Yes. NORVI Expansion Modules are designed with industrial reliability in mind — featuring opto-isolated inputs/outputs, durable connectors, and protection against electrical noise.
