What are Analog Inputs?
Analog inputs refer to the interfaces or ports on a device, such as a microcontroller, PLC (Programmable Logic Controller), or sensor, that are designed to accept analog signals. These inputs are crucial for acquiring and processing continuous real-world data that varies in amplitude or intensity over time.
Analog inputs typically allow the connection of sensors or devices that generate analog signals, such as temperature sensors, pressure transducers, potentiometers, strain gauges, and many others. These sensors produce signals that represent physical quantities like temperature, pressure, voltage, light intensity, etc., in analog form, which means they provide a continuous range of values.
Devices equipped with analog inputs use analog-to-digital converters (ADCs) to convert the incoming analog signals into digital form, which can be processed, analyzed, stored, or used by digital systems like microcontrollers or computers. The ADCs sample the analog signal at discrete intervals and assign digital values to represent the amplitude of the analog signal at those points in time.
Analog inputs are essential in various fields, especially in industrial automation, robotics, data acquisition systems, and scientific instrumentation, where precise measurement and control of analog data are critical for operations and analysis.

Norvi IoT devices are ESP32 integrated industrial controllers which come with a number of features that make them suitable for industrial automation and IoT solutions. These devices come equipped with digital and analog I/O , enabling them to detect digital logic states and analog inputs, depending on the choice of the model. The inputs can come from several sources. In general cases, the source of input can pose a potential threat to the system, but the Norvi devices ensure isolated digital inputs for added protection.
Variety of models in the Norvi lineup are capable of measuring the environmental factors like flow rate, pressure, temperature and offer analog inputs (for dedicated voltage/current measurement) at the industrial level.
With the Norvi relaymodel, it becomes simple to control the industrial appliances. When it comes to digital outputs in this relay model, both relays and transistor outputs perform the same task. However, compared to transistors, switching can be far slower in relays, and relays emit clicking sounds. Moreover, relays also have a larger appetite for current consumption. The transistors are smaller in size and silent in operation and affordable.
Setting up the Norvi devices only require lesser wiring, which offers more flexibility to management of the device. Also the sinking and sourcing capabilities within Norvi industrial ESP32 IoT devices ensures that current flows in either direction. Hence the machines are capable of switching inputs between sink and source functions.
