Product Description:

The S20-AI-4-RTD is a temperature input module manufactured by Bosch Rexroth Indramat. This temperature input module is a part of the S20 IndraControl Modules series, which is specifically designed to be used with RTD (Resistance Temperature Detector) sensors. This module has four input channels, meaning that the module requires four sensors to measure the temperature in four locations simultaneously. It also has a 16-bit resolution, and that means that it is capable of detecting very small changes in temperatures, hence it is highly accurate.

Popular types of RTD sensors that are supported by this input module are Pt100, Pt200, Pt500, Pt1000, and Ni100, Ni1000. It is designed with 2 wires, 3 wires or 4 wires measurement technology, which makes it flexible, depending on the application as well as the requirement of the systems. The Pt100 sensor is ideally applicable in both low and high-temperature environments, considering that it has an operating temperature range of -200 degrees C to +850 degrees C. This module offers quick and accurate measurements with a conversion speed of approximately 7 milliseconds per channel and a measuring error of less than 0.1 %.

The S20-AI-4-RTD is a sensor that operates on a 24 V DC power supply, and it communicates via the S20 bus system. It is equipped with push-in spring connections, which allow easier and more secure installation. Depending on the supplier, the module is further CE, cULus, and ATEX approved to make sure that it conforms to globally accepted safety and performance requirements. This makes it perfect for working areas such as factories or power plants, and systems that require precise temperature monitoring. Its small size and plug-in installation make it appropriate for most automation projects.
