Product Description:

The X20ATA492 is a dual-channel input module in the B&R Automation X20 series designed for accurate acquisition of analog signals within industrial control systems. It converts analog values into precise digital data for processing by the automation system. This ensures consistent and accurate feedback from connected sensors. This module comes equipped with 2 inputs that are suited for thermocouple sensors. This allows it to accurately measure temperature in industrial applications by interfacing directly with standard thermocouples. The two channels are electrically isolated from each other to ensure signal integrity and enhanced system safety.

The X20ATA492 includes 2 integrated PT1000 sensors within the terminal, allowing for direct temperature measurement at the module location. These sensors can be used to monitor ambient temperature or for cold junction compensation when working with thermocouples. This integration improves the accuracy of thermocouple readings by accounting for local temperature variations. For both module operation and input status the module offers simplified diagnostics via software and accessible LED indicators. This enables users to quickly identify issues such as hardware malfunctions or configuration problems.

The X20ATA492’s 16-bit resolution allows the module to detect very small changes in temperature, delivering detailed and reliable measurements. This unit can be tailored to meet varying system demands. Users can configure the filter time ranging from 1 ms to 200 ms, to achieve the desired responsiveness and stability of signal processing. Shorter filter times enable faster response to rapid temperature changes, while longer filter times help smooth out signal noise. The module is adaptable to most industrial environments and can operate optimally at -25 to 60°C. It can be mounted horizontally or vertically in control cabinets providing flexibility in installation, though care should be taken to avoid exposure to moisture.
