PLCs, Power Supplies & Others

Product Overview

The Siemens 6ES5464-8MA11 provides four isolated analog input channels for the SIMATIC S5-90U, S5-95U, S5-100U, ET 100U, and ET 200U PLC systems . This module specifically accepts ±50 mV signals and converts them into 13-bit digital values for precise process monitoring . Moreover, the 6ES5464-8MA11 supports thermocouple connections, making it suitable for temperature measurement applications .

Technical Specifications

This analog input module operates with a 24 V DC supply voltage and weighs approximately 0.20 kg . The unit features a compact modular design that facilitates easy installation within existing S5 system racks. Furthermore, the 6ES5464-8MA11 provides floating inputs that ensure excellent noise immunity in electrically noisy industrial environments .

Key Design Features

The 6ES5464-8MA11 features a front-panel operating mode switch that allows users to set the integration period for optimal power supply rejection . Consequently, you can select 50 Hz or 60 Hz operation to match your local mains frequency. This module also includes a wire-break detection function; a red LED illuminates and the fault bit sets when a sensor wire breaks . The module’s floating design effectively eliminates ground loop problems that often compromise measurement accuracy .

Application and Integration

This analog input module integrates seamlessly with the S5-90U, S5-95U, and S5-100U controllers, providing high-precision data acquisition for legacy automation systems . The 6ES5464-8MA11 proves particularly valuable for temperature measurement using thermocouples; a compensating box connects directly to terminals 1 and 2 to compensate for cold junction temperature effects . Consequently, industries such as manufacturing, energy, and process control continue to deploy this module for critical monitoring tasks.
