Siemens SITOP PSE200U selectivity module, 6EP1961-2BA11, 4x0.5-3A adjustable, 24V/12A input, marine approved.
The Siemens SITOP PSE200U 6EP1961-2BA11 is a 4-channel selectivity module for 24 V DC systems, taking a 12 A input and splitting it across four outputs each adjustable from 0.5 to 3 A, with a common signaling contact for remote status. It isolates an overloaded branch circuit while the other three channels stay powered.
The 0.5-3 A adjustable threshold per channel and 12 A input current size this module for lower-current 24 V branch circuits than the higher-current 4x10A selectivity modules in the same family; pick this variant when individual branch loads stay under 3 A. The non-isolated 24 V remote reset input lets a PLC clear a tripped channel without manual intervention at the cabinet, and the marine classification approvals (ABS, DNV) make it a fit for shipboard control panels where the plain diagnostics module is not certified.
Protects multiple independent 24 V DC branch circuits - sensors, small valve solenoids, remote I/O nodes - downstream of a single power supply, so a short on one output trips only that channel and the signaling contact reports which one.
