Why SITOP SEL1600?

The SITOP SEL1600 is a modular selectivity system designed to protect up to 40 load circuits against short circuits or overloads. It provides reliable protection by safely disconnecting faulty load circuits while maintaining a reaction-free 24 V power supply to other circuits. Its modular expandability from 4 to 40 outputs combines with bidirectional IO-Link for remote parameterization and diagnostics.
The system consists of:

  • SITOP SEL1600 basic module (1x)
  • SITOP SEL1600 expansion modules (up to 9)

ประโยชน์ที่สำคัญ

Architecture Openness Icon - Seamless Integration Blox

Integrate easily

Integrate the selectivity system via IO-Link into your automation system, the proven I/O technology for read/write with high EMC. Visualize the 24V branches via free faceplates in WinCC.

SITOP SEL1600 safely switches off faulty 24 V feeders and thus avoids a possible system downtime

Reliably protect the control circuit

Switch off 24V feeders reliably and quickly in the event of an overload or short circuit so that all other feeders and their consumers, such as the PLC, continue to be supplied without retroactive effect.

The basic module has 4 outputs and can be expanded to up to 40 outputs via expansion modules

Expand flexibly

The basic module has 4 outputs and can be expanded to up to 40 outputs via expansion modules. The response threshold is adjustable from 0.5 to 10 A. Two adjacent outputs connected in parallel increase the current to 20 A.
