Description
B&R 7AT324.70 Input Module
Product Dimensions：
The B&R 7AT324.70 is a high-performance analog input module from B&R Industrial Automation’s X20 System series. It is specifically designed for temperature measurement using resistance temperature detectors (RTDs).
Detailed Product Description
The 7AT324.70 module features 4 channels for temperature measurement. It is built to interface seamlessly with the X20 backplane, offering a compact and modular solution for industrial thermal monitoring. The module provides high resolution and integrated filtering to ensure accurate data even in electrically noisy industrial environments.

Product Advantages
-
High Precision: 16-bit resolution allows for extremely fine temperature monitoring, which is critical for sensitive chemical or food processing applications.
-
Compact Design: The X20 system’s slim profile saves significant space in the control cabinet compared to traditional PLC modules.
-
Easy Integration: Full compatibility with B&R Automation Studio, allowing for “plug-and-play” configuration and diagnostics.
-
Robustness: Features built-in galvanic isolation and noise filtering to protect the internal circuitry and ensure signal integrity.
-
Flexible Connection: Supports both 2-wire and 3-wire connections to accommodate different sensor cable lengths and accuracy requirements.
Important Considerations (Notes)
-
Terminal Block Requirement: The module requires a separate X20 terminal block (e.g., X20TB12) for wiring, which is usually sold separately.
-
Cable Shielding: For maximum accuracy and to avoid electromagnetic interference (EMI), use shielded twisted-pair cables.
-
3-Wire Compensation: When using 3-wire sensors, ensure all three wires have the same resistance to maintain the accuracy of the lead-wire compensation.
-
Firmware Updates: Ensure your B&R controller firmware is compatible with the hardware revision of the 7AT324.70 module.
Product Applications
The 7AT324.70 is widely used in industries where precise thermal control is mandatory:
-
Plastics Industry: Monitoring heater bands on injection molding machines.
