Expansion modules for increasing system availability up to total all-round protection

Siemens SITOP Add-on Modules is a series of Expansion modules for increasing system availability up to total all-round protection. SITOP offers you a unique range of perfectly integrable expansion modules for reliable protection against a wide variety of potential hazards on the primary and secondary side. The SITOP add-on modules allow the completely flexible expansion of SITOP power supply units and extension up to total, all-round protection.

FEATURES

SITOP redundancy module

  • Highly secure DC supply thanks to a redundant design
  • Reliable supply even when one power supply fails
  • Compact redundancy modules for power supply units up to 48 V and 40 A
  • 24-V/NEC Class 2 redundancy module limited to 100 VA
  • Decoupling of parallel-connected power supply units to enhance performance or of series-connected power supply units to increase voltage

SITOP selectivity module

  • Protection against overloads and short circuits in the 24-V circuit
  • Reliable tripping, regardless of the line resistance
  • SEL1200: switch-off characteristic for standard protection and high starting currents
  • SEL1400/PSE200U: power limiting to meet high protection requirements by stabilizing the 24 V
  • Sequential connection reduces total inrush current
  • Common signaling contact or evaluation of individual channels
  • SEL1200/1400: 8 outputs, each with diagnostics of voltage, current, set threshold, reason for disconnection (if applicable)
  • PSE200U: 4 outputs with voltage measuring point for current (1 V ≙ 1 A)

SITOP buffer module

  • Economical protection against power failure up to the seconds range
  • Support for the power supply unit when the power demand temporarily increases
  • High load current up to 40 A
  • Only two lines connecting to the power supply unit

SITOP inrush current limiters

  • Maximum service life of current-sensitive components like relays thanks to reduced current inrushes
  • Space-saving, thanks to narrow width of only 18 mm
  • Suitable for LOGO! modules and sub-distribution boards, thanks to its stepped profile
  • Flexible installation on the DIN rail, on the wall or in various other locations
  • Maximum plant configuration enabled
  • Flexible application options at temperatures ranging from -40° Celsius to +70° Celsius
