Manual for SITOP select 6EP1961-2BA00

In conjunction with a 24 V power supply, the selectivity module is used to distribute the load current across several branches and to monitor the individual currents in these branches. Faults in the individual branches caused by overload or short-circuit are detected and selectively switched off, so that the fault does not impact the other load circuits. This means fast troubleshooting and minimized downtimes. The response threshold can be continually set for each output using a potentiometer. Overcurrents are reliably switched off, independent of the cable length and cable cross-section. The 24 V supply for the other loads is maintained. Multi-colored LED for each output for faster troubleshooting on-site. Floating group signal contact for remote diagnostics. Single-channel signal to serially indicate the state of the individual outputs. Evaluation using free-of-charge SIMATIC S7 function blocks. Load branches can be sequentially switched on to reduce the total inrush current.
