SITOP SEL1200/SEL1400 Selectivity Modules
Siemens SEL1200 and SEL1400 power reliability selectivity modules offer efficient protection for users’ plants
Siemens SITOP selectivity modules distribute the load current across several 24 VDC load circuits and monitor them reliably for overload and short-circuit conditions. The electronics permit brief current peaks caused, for example, by high inrush currents but isolate load circuits in the event of an extended overload even on high-resistance lines. In this case, miniature circuit breakers fail to trip or trip too late even if the power supply unit could deliver the required tripping current. The SITOP SEL modules continue to consistently supply 24 V to the load circuits that are not affected by an overload and can prevent a total system failure. The modules, which have more outputs, an additional tripping characteristic, and detailed diagnostics, now offer even more efficient protection for the user plant.
- Increased availability in case of short-circuit and overload
- Safe shutdown of faulty circuit
- Complete functionality regardless of wire length and section
- Fast error diagnostics
- LED status display on device
- Group alarm or diagnostics interface with single-channel diagnostics for existing output current, the configured current threshold value, and the cause of switch-off if required
- Supports power supply
- Avoids high inrush current by using sequential channel connection
- Flexible deployment
- Individually adjustable response threshold for each output
- Parallel connection of 2 outputs for increased performance
- Tripping during operation only in the event of a fault
- Reliable supply even in case of high inrush current
- Easy commissioning
- Switching via pushbutton for each output
- 4 or 8 outputs per module
- Slim width
- Push-in terminals for easy installation
- Comparison of selectivity modules SITOP SEL1200 und SITOP SEL1400 solution for high and highest operational safety
- Selectivity module SEL1200 with switching electronic characteristics
- Selectivity module SEL1400 with limiting electronic characteristics
- Process automation, e.g., food and beverage industry
- Fast error assignment by evaluation of the diagnostic interface in the controller
- Adjustable output voltage to compensate for voltage fluctuations
- Minimize downtime by avoiding short circuits with selective 24 V monitoring
- Manufacturing automation, e.g., packaging industry and electronics production
- Compact design - without lateral installation clearance – saves space in control cabinet
- Machine and control cabinet construction, e.g., serial and special machine construction
- Easy and fast commissioning due to easy installation with push-in terminals
