Description

The Siemens 6ES5 930-8MD11 (PS930) is a dedicated power supply module engineered for the Simatic S5-090, S5-095, and S5-100 controller families. This unit converts a 230 VAC input voltage into a regulated 24 VDC output, providing a consistent 1 A current capacity to support small-scale automation logic. It is widely utilized in distributed control architectures, light manufacturing equipment, and environmental monitoring systems where reliable low-power DC delivery is essential. By maintaining high voltage stability and filtering transient line noise, this module plays a key role in preventing spurious controller resets and system failures, thereby optimizing uptime in compact industrial automation deployments.

Features

Designed for seamless integration with Simatic S5-090, S5-095, and S5-100 series controllers.
Integrated switched-mode power converter for high energy efficiency and effective thermal management.
Built-in protection mechanisms against short-circuit events and over-voltage conditions.
Low ripple voltage output to ensure stable signal processing and logic execution.
Compact modular housing optimized for standard control cabinet mounting and convection cooling.

Applications

This power module is primarily used in legacy Simatic S5 automation systems, including small-scale machine control, distributed I/O stations, and specialized environmental monitoring setups requiring stable 24 VDC power.

Installation Guidelines

Ensure the control cabinet power is fully disconnected before installing or removing the module from the S5 backplane.
Verify that the input voltage matches the 230 VAC nominal rating to prevent damage.
Maintain adequate clearance around the module to allow for natural convection cooling; do not obstruct the ventilation slots.
Ensure the module is firmly seated in the S5 rack to maintain proper electrical contact with the backplane bus.
Use appropriate shielded cabling for DC output distribution to minimize electromagnetic interference (EMI) in sensitive control environments.
Handle with standard ESD precautions to protect internal electronic components.

FAQ

Is the Siemens 6ES5 930-8MD11 compatible with S5-115U systems?

No, this specific PS930 module is designed specifically for the S5-090, S5-095, and S5-100 series. It is not intended for use in the larger S5-115U or S5-135U/155U rack systems.

Does this module require external cooling?

The module is designed for natural convection cooling. Ensure that the installation environment remains within the specified 0 deg C to 60 deg C operating range and that airflow is not restricted by adjacent components or wiring ducts.
