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
