Analog input modules are essential for integrating sensors and process signals into PLCs, data acquisition (DAQ) systems, and industrial controllers. Whether you're wiring temperature probes in a plant or measuring voltages for an engineering lab project, selecting a suitable analog input module ensures reliable, accurate data capture for your system.
Communica stocks a comprehensive range of analog input modules for rapid online ordering - from basic educational breakouts to industrial-grade PLC and remote IO cards. Top brands include ABB, Siemens, Schneider Electric, WAGO, and maker favourites like Arduino and Adafruit, all available for delivery across South Africa or convenient collection at our Samrand, Pretoria, and Cape Town branches.
Analog input modules receive and digitise real-world signals (voltage or current) from field devices, such as:
These modules are fundamental for automation, process control, building management, and robotics. They're also widely used in educational environments where students need to capture analog signals from physical phenomena.
| Input Type | Typical Use | Sample Model |
|---|---|---|
| 0-10V, 10V Voltage Input | General sensors, potentiometer readings | Siemens SM 1231 |
| 0-20mA, 4-20mA Current Loop | Industrial process transducers | WAGO 750 Series |
| Thermocouple/RTD Modules | Temperature monitoring | ABB AI561 |
| Maker Modules (ADC/HATs) | Prototyping with Arduino, Pi, micro:bit | Adafruit ADS1115, MCP3008 |
When ordering online, confirm your PLC, DAQ, or microcontroller platform compatibility and the signal range required for your application.
When you order an analog input module, consider the following:
| Model | Channels | Resolution (bits) | Isolation |
|---|---|---|---|
| ABB AI561 | 8 | 12 | Yes |
| Adafruit ADS1115 | 4 | 16 | No |
| Siemens SM 1231 | 8 | 13 | Yes |
Comparing your application requirements against key specs in the product datasheet will help ensure your module meets your performance needs.
