Siemens 6EP1961-2BA11 Selectivity Module SITOP PSE200U
The Siemens 6EP1961-2BA11 is a crucial component in industrial power distribution systems known as the SITOP PSE200U Selectivity Module. This device is not a power supply itself but an intelligent add-on module designed to provide selective protection and diagnosis for downstream 24 V DC circuits. It is engineered to seamlessly integrate with Siemens SITOP power supplies.
The primary function of the PSE200U is to ensure that in the event of an overload or short circuit on one output branch, only the faulty branch is disconnected, while the other healthy loads continue to receive power without interruption. This functionality is often referred to as selective tripping.
Key features and specifications include:
-
Function: Selectivity and Diagnosis Module. It monitors the current on its output channels.
-
Output Channels: This specific model typically provides four output channels, allowing up to four separate circuits to be monitored and protected individually.
-
Output Current: Each output channel is individually adjustable, often allowing users to set the tripping current between 0.5 A and 3 A. The total current for the module is typically rated up to 10 A.
-
Diagnosis: The module features diagnostic capabilities. It signals overloads or short circuits via both LED indicators for local visualization and a group alarm signal for remote monitoring (e.g., via a PLC).
-
Reset Function: It includes remote control functionality for resetting the tripped channels.
-
Mounting: Designed for easy and secure mounting on a DIN rail within the control cabinet.
In summary, the Siemens SITOP PSE200U selectivity module 6EP1961-2BA11 significantly enhances system availability by reliably isolating faulty 24 V DC branches, preventing unnecessary tripping of the main power supply, and providing valuable diagnostic information.
