SITOP PSE200U selectivity module, 4x3A NEC Class 2 outputs, 0.5-3A adjustable, per-output status signal.
The Siemens 6EP1961-2BA61 is a SITOP PSE200U selectivity module that splits a 24 V DC/12 A input into four individually protected 3 A NEC Class 2 outputs, with a status signal output per channel instead of one shared alarm contact. Each output trips independently at an adjustable 0.5-3 A threshold set via potentiometer, and its pulse/pause status signal can be evaluated directly by a Simatic function block.
Pick the 2BA61 over the 2BA51 when the controller needs to identify which of the four channels tripped, not just that one has - the per-output pulse/pause signal line resolves fault location without extra wiring back to a shared contact. The signal is built for direct evaluation by a Simatic function block, which fits a SIMATIC-based control architecture more directly than a shared relay contact. Everything else - the 12 A input rating, 0.5-3 A adjustable trip point, IP20 enclosure - is identical across the PSE200U line, so the choice comes down to how much per-channel diagnostic resolution the application needs.
Fits selective load protection downstream of a 24 V DC/12 A SITOP supply where the control system needs to know exactly which of four branches faulted - useful in cabinets with SIMATIC PLC I/O, remote stations, or HMI branches that must be diagnosed individually rather than as one combined alarm.
