Product Information
Full details
The Siemens 6EP1961-2BA00 SITOP selectivity module is designed for 24V power supply systems, offering enhanced control over load current distribution across multiple branch circuits. Its primary benefit is the ability to detect and selectively switch off overloads and short-circuits on individual feeders, preventing cascading failures and improving system reliability. A potential consideration is its operational range, particularly concerning ambient temperature for intact feeders, which requires adherence to specifications for optimal performance.

Extended Product Information
FAQs
What is the primary function of the Siemens SITOP selectivity module?
Its primary function is to distribute load current across multiple output circuits and to monitor each circuit for overloads or short-circuits, selectively switching off faulty channels to protect the system.
What is the current monitoring range for each channel?
The current monitoring range for each channel is adjustable from 2 Amps to 10 Amps.
What type of power supply is required for this module?
This module is designed for use with 24V DC power supplies.
What are the operating temperature limits?
The ambient temperature range for an intact feeder is from -25°C up to +60°C.
How does the module indicate a fault on a channel?
The module identifies errors on individual circuits, typically through status indicators (though specific indicator details would be in the full manual) and by selectively switching off the faulty channel.
What is the physical size of the module?
The module has a width of 72mm, a height of 90mm, and a depth of 90mm.
Does this module protect against overvoltage?
This module is designed for overcurrent protection on individual DC load circuits. Overvoltage protection is typically handled by the main power supply unit.
Troubleshooting
Module does not power on.
Verify that the control supply voltage (22-30V DC) is correctly connected and within the specified range. Check the integrity of the power supply itself.
A specific output channel is not supplying power.
Check if the current limit for that channel has been exceeded, triggering a shutdown. Verify the load connected to the channel is not drawing excessive current. Ensure the channel is not manually switched off if such functionality exists.
False tripping of a channel.
Ensure the set current threshold is appropriate for the load. Transient current spikes during startup might require a slightly higher setting or a delay-on function if available on the power supply.
Overheating of the module.
Ensure proper ventilation. Check if the total load current across all channels is within the module's overall capacity and that individual channel limits are not exceeded. Reduce ambient temperature if possible.
Pros and Cons
Pros
- Enhances system reliability by isolating faulty circuits.
- Simplifies troubleshooting by pinpointing issues to specific feeders.
- Protects sensitive equipment by preventing overcurrent conditions.
- Offers flexibility with adjustable current monitoring.
- Compact form factor for easy integration.
Cons
- Requires a 24V DC power supply to operate.
- Ambient temperature limits (-25°C to +60°C) must be observed for intact feeders.
- Primarily designed for DC voltage applications.
- Additional configuration may be needed for specific protection settings.
Setup, Compatibility & Care
Setup:
- Connect the module to a suitable 24V DC power supply using the screw terminals for the control supply voltage (22-30V DC).
- Connect the main 24V DC input from the power supply to the module's input terminals.
- Connect each load circuit to the individual output channels.
- Set the desired current monitoring threshold for each channel using the integrated adjustment (2-10A).
Compatibility:
- Compatible with 24V DC power supplies.
- Suitable for use in environments with ambient temperatures ranging from -25°C to +60°C for intact feeders.
- Utilizes screw connections for electrical connections.
Care:
- Ensure the module is installed in a well-ventilated area to maintain operating temperatures.
- Periodically inspect connections for tightness and signs of wear.
- Keep the module clean and free from excessive dust or debris. A dry or slightly damp cloth can be used for cleaning; avoid harsh chemicals.
