Function and Working Principle

The 6AG1961-3BA10-6AA0 provides an interface between a compatible SITOP power supply and the wider industrial control system. Its main purpose is to make power supply status information available through signaling contacts.

1. Output Voltage Monitoring

The output voltage OK signal provides information about the condition of the power supply output. This signal can be used by a PLC, relay circuit, or other compatible monitoring equipment to identify whether the supply output is within its intended operating condition.

For example, a PLC can monitor the signal and generate an alarm if the power supply no longer reports a healthy output condition. The controller can then initiate a predefined response, such as stopping a machine sequence or notifying the operator.

The signal should be interpreted according to the module’s wiring diagram and the connected power supply’s operating characteristics.

2. Operational Availability Signaling

The operational availability OK function provides an additional indication of the power supply’s readiness for operation.

This information is useful in automated systems where the availability of control power must be checked before equipment is allowed to start. A PLC can use the status signal as part of a start-up permissive or equipment interlock.

By incorporating power supply readiness into the control logic, engineers can reduce the risk of starting equipment when the required DC supply condition is not available.

3. Remote ON/OFF Control

The signaling module also provides a remote ON/OFF function for compatible power supply configurations.

This allows an external control arrangement to manage the power supply’s operating state where the connected equipment and wiring support the function. It can be incorporated into a machine-control sequence or a centralized power management strategy.

Remote control should be implemented according to the manufacturer’s wiring instructions. It should not be treated as a substitute for safe electrical isolation during maintenance.

4. Hard Gold-Plated Contacts

The 6AG1961-3BA10-6AA0 features hard gold-plated contacts. Contact surface quality is important in low-level signaling circuits because poor contact conditions can affect the reliability of status transmission.

Gold plating helps provide stable contact performance in suitable applications. The complete contact rating and wiring requirements must still be checked before connecting external circuits.

5. Environmental Protection

As a SIPLUS product, this module is designed for applications involving environmental media exposure. Its specified version includes hard gold-plated contacts and an operating temperature range of 0 to +60 °C.

The environmental properties do not mean that the module can be installed without considering cabinet protection, humidity, chemical exposure, temperature, or contamination. The actual installation environment must remain within the manufacturer’s stated limits.

Role in Industrial Control Systems

The 6AG1961-3BA10-6AA0 helps integrate power supply monitoring into industrial automation systems. It provides status information that can be used by PLCs, control relays, and supervisory systems.

PLC Integration

A PLC can receive the signaling module’s output status through compatible input circuits. The controller can then evaluate whether the power supply reports normal output voltage and operational readiness.

For example, a PLC may prevent a production line from starting until the required power supply status signals are confirmed. If a monitored condition changes during operation, the controller can activate an alarm or execute a predefined shutdown sequence.

The exact wiring arrangement depends on the connected SITOP power supply, the signal contact configuration, and the PLC input requirements.

HMI and Operator Monitoring

A human-machine interface can display power supply status information received through the PLC. Operators may see whether the supply is operating normally or whether a power-related alarm requires attention.

This improves visibility into the condition of the control cabinet and can help maintenance personnel identify the source of an equipment interruption more quickly.

Power Distribution Management

In systems with multiple DC power supplies, monitoring individual supply conditions can help engineers understand the availability of control power across different sections of a machine.

The signaling module can contribute to a broader power management strategy by making important supply conditions available to the control system.

Machine Interlocking

Power supply status can be incorporated into machine permissives and interlocks. For example, the PLC may require confirmation that the relevant control power supply is ready before energizing downstream equipment.

Such logic can help prevent operation under unsuitable power conditions. Safety-related functions must still be implemented using appropriately rated safety equipment and validated safety circuits.

Industrial Applications

The Siemens 6AG1961-3BA10-6AA0 is suitable for compatible SITOP power supply installations where power status monitoring and remote control are required.

1. Industrial Control Cabinets

By making power supply status available to the PLC, the module can support alarm generation, start-up checks, and predefined responses to abnormal conditions.

3. Packaging Machinery

Packaging equipment often contains several control circuits and electronic devices that require dependable DC power.

The module can help monitor the condition of compatible SITOP power supplies used in the machine cabinet. The PLC can use the available signals to determine whether the power supply reports the required operating status.

4. Material Handling Systems

Conveyors, sorting equipment, and automated material-handling systems may operate continuously across multiple control zones.
