Siemens 6ES7134-4NB51-0AB0

Siemens 6ES7134-4NB51-0AB0 RTD High Feature Module

The Siemens 6ES7134-4NB51-0AB0 is a high-precision electronic module engineered for temperature measurement within the SIMATIC DP ET 200S distributed I/O system. Specially designed for integration with resistance temperature detectors (RTDs), this RTD High Feature module delivers outstanding accuracy, compact form, and dependable signal processing capabilities. With a narrow 15 mm width and advanced support for 2-, 3-, and 4-wire RTD sensors, it fits easily into tight control cabinets while delivering exceptional analog input performance. Whether deployed in factory automation, process control, or temperature-critical applications, this module ensures precision, reliability, and compatibility across various industrial scenarios.

Exceptional Measurement Accuracy for Temperature-Critical Systems

At the core of the 6ES7134-4NB51-0AB0 module is its ability to deliver highly accurate temperature readings with a resolution of 15-bit plus sign and an accuracy tolerance of ±0.1%. This makes it well-suited for applications where even the slightest deviation in temperature can affect product quality or process efficiency. Industries such as pharmaceuticals, chemical processing, and food manufacturing often rely on this level of accuracy to maintain compliance and quality control standards. The module ensures that even subtle changes in sensor input are correctly translated into reliable data for automation systems.

Comprehensive Sensor Compatibility and Compensation

This RTD High Feature module supports 2-, 3-, and 4-wire RTDs, including standard types like Pt100 and Pt1000, offering users the flexibility to match existing sensors or optimize new installations. Internal compensation for line resistance ensures stable readings even when sensors are installed far from the control cabinet—an essential feature in large machines or remote temperature monitoring applications. This built-in intelligence helps eliminate errors caused by voltage drops in long cables, providing accurate measurement regardless of wiring layout.

Robust and Compact Design for Industrial Environments

Despite its slim 15 mm width, the Siemens 6ES7134-4NB51-0AB0 is built to handle the demands of industrial automation. It features an integrated SF (system fault) LED for real-time diagnostics, alerting operators instantly in case of connection issues or sensor malfunctions. This diagnostic capability reduces downtime and speeds up troubleshooting efforts. As part of the ET 200S family, the module easily integrates into existing PROFIBUS networks, enhancing system scalability while maintaining efficient communication with PLCs and SCADA systems.
