Applications
Industrial Automation
Expand your controller with analog, digital, relay, or transistor I/O modules to connect sensors, actuators, and machines for automated process control.
Data Acquisition Systems
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.
Process Control
Drive control loops with analog output expansions for variable frequency drives (VFDs), valves, or proportional actuators, ensuring precise and stable operation.
Machine Monitoring
Use digital input and transistor output modules for real-time status monitoring, fault detection, and alert systems in production equipment.
Remote Monitoring & IoT
Pair expansions with LoRa, NB-IoT, or GSM modules to send collected data wirelessly to cloud platforms for analysis and predictive maintenance.
Building & Energy Management
Relay and transistor outputs can control lighting, HVAC systems, and energy loads, while analog inputs track power, voltage, or current sensors.
Test & Measurement Systems
High-resolution input/output modules are ideal for lab setups, prototypes, and industrial test benches requiring precise signal handling.
Custom OEM Solutions
Mix and match expansion modules to create tailored controller solutions for your specific industry or product line, without redesigning hardware.
FAQ – NORVI Expansion Modules
Expansion modules extend the I/O and communication capabilities of NORVI industrial controllers. They add analog inputs/outputs, digital inputs, transistor or relay outputs, and wireless connectivity options.
You can connect up to six general expansion modules or eight I²C-based expansions in a daisy chain, depending on the controller and module type.
Most modules use the I²C bus for communication, while some specialized modules also support UART connections for data exchange.
Yes. Analog, digital, relay, transistor, and wireless modules can be mixed in the same system, giving you flexibility to match your application needs.
Yes. Digital inputs are optically isolated and rated up to 36V DC, transistor outputs support up to 36V DC, and relays can switch 5A at 250V AC or 30V DC.
Analog input modules use a 16-bit ADC (ADS1115) for high-precision measurements, while analog output modules provide 12-bit DAC resolution for smooth control signals.
Most modules draw power directly from the NORVI controller’s expansion port. However, modules driving higher loads (e.g., relay outputs) may need external supply as per datasheet specs.
They are widely used in industrial automation, process control, sensor integration, data acquisition, remote monitoring, and IoT edge computing solutions.
