Redundancy modules SITOP redundancy modules - High availability of the 24 V DC supply thanks to redundant configuration
- Decoupling of two power supplies of the same type in parallel operation via diodes
- 24 V DC power supply is maintained in the event of a power failure
- Compact redundancy modules for power supply units up to 40 A
- Diagnostic signal via LED and signaling contacts
- Adjustable switching threshold for LED and signaling contacts
- Direct integration in SIMATIC PCS 7 via SITOP library
Buffer module SITOP buffer module - Buffering the load current during brief power interruptions
- Maintenance-free capacitors with short charging times as energy storage units
- Wiring parallel to the output of the power supply
- Parallel switching of several buffer modules possible
- A supply voltage > 20.5 V is signaled by an LED on the device.
- Buffer time up to: 200 ms at 40 A, 400 ms at 20 A, 800 ms at 10 A, 1.6 s at 5 A load current
Selectivity modules SITOP selectivity modules - Distribution of the load current over up to 4 current circuits with individually adjustable maximum current
- Monitoring of individual partial currents
- Reliable tripping regardless of cable lengths and cross-sections
- Selective cutoff of current circuits at overload or short-circuit
- Simple commissioning thanks to manual switch on/off of outputs
- Sequential connection delay of feeders reduces total inrush current
- Sealable transparent cover over adjusters for currents and times protect against maladjustment
- Remote reset possible from a central location
- Signaling via LEDs (channel-by-channel) and remote diagnostics via common signaling contact or single-channel signaling
- Evaluation of the status of 4 current circuits of selectivity modules with single-channel signaling via SIMATIC S7 function blocks.
- Direct integration in SIMATIC PCS 7 via SITOP library
