Description
Description
The Siemens 6ES5470-4UA12 is an analog output module designed for use within the SIMATIC S5-135U and S5-155U programmable logic controller (PLC) systems. This module provides 8 channels of analog output, allowing for precise control of field devices such as actuators, valves, and variable frequency drives. As a legacy component of the SIMATIC S5 family, it is engineered to provide reliable signal conversion for industrial automation processes.
Features
- 8-channel analog output capability for multi-loop control applications.
- Configurable output ranges including +/- 10V and 0-20mA to suit various instrumentation requirements.
- Designed for integration with the robust S5-135/155 rack-based architecture.
- Standard 24 VDC power supply operation.
Applications
This module is typically utilized in legacy industrial control environments where SIMATIC S5 systems remain in operation. It is suitable for process control loops, motor speed regulation, and positioning tasks that require high-resolution analog signaling.

Installation Guidelines
- Ensure the PLC rack is powered down before inserting or removing the module to prevent electrical damage.
- Verify that the module is fully seated in the backplane connector to ensure reliable communication with the CPU.
- Use shielded twisted-pair cabling for analog signals to minimize electromagnetic interference (EMI) from high-voltage lines or motors.
- Maintain proper ventilation in the control cabinet to prevent overheating, as legacy modules may be sensitive to ambient temperature fluctuations.
- Ensure proper grounding of the cable shields at the control cabinet entry point to maintain signal integrity.
FAQ
Is the 6ES5470-4UA12 still in production?
No, this module has been discontinued by the manufacturer. It is primarily available through secondary market channels for maintenance and repair of existing SIMATIC S5 systems.
Can this module be used in an S5-115U system?
The 6ES5470-4UA12 is specifically designed for the S5-135U and S5-155U series. Compatibility with other S5 series should be verified against your specific rack and CPU configuration documentation.
