IoTextra Analog: Industrial-Grade 4-Channel 16-Bit Analog Input Module

The Ultimate Solution for High-Precision Analog Monitoring

Achieve industrial precision and versatility in your embedded projects with the IoTextra Analog module. Built around the high-resolution 16-bit ADS1115 ADC from Texas Instruments, this module offers 4 truly differential input channels capable of reliably measuring a wide range of analog signals, including both voltage and current, and the essential 4-20mA industrial standard.
The IoTextra Analog is designed for mission-critical applications where every detail matters: from monitoring industrial sensors to PLC integration and building complex control systems.

Key Features and Benefits

Detailed Technical Specifications

Primary Applications

• Industrial Automation (PLCs): Reliable monitoring of industrial sensors and current loop sensors (4-20mA).
• Energy Monitoring: Accurate measurement of voltage and current parameters in power management systems.
• Environmental Control: High-precision data acquisition from temperature, pressure, and humidity sensors.
• Transportation and Automotive: Test benches, applications for transmission sensors, and infotainment systems.
• Development and Prototyping: A powerful and flexible analog front-end for any embedded system.

Ecosystem Compatibility

The IoTextra Analog is designed for maximum modularity and can be used in three modes:

• Standalone Use: Connects to any controller via Qwiic® or HOST connectors.
• Smart Use: Plugs directly into an IoTsmart module (e.g., RP2350, ESP32-S3) to create an integrated controller.
• Mezzanine Use: Installs into an IoTbase carrier board for expanded connectivity and mechanical stability.

This module is a member of the loTextra series, which serves as a fundamental building block of our ecosystem and embodies the Make Things Happy Philosophy. It is engineered to bridge the gap between rapid prototyping and industrial-grade reliability.

Hardware Synergy: The module is compatible with both IoTsmart and IoTbase series. 

Software Power: This hardware compatibility unlocks the full potential of the IoTflow platform. It enables you to:

• Create custom Node-RED nodes effortlessly.
• Integrate via MQTT with third-party global platforms like Blynk.
• Scale your project from a single node to a complex industrial network.
