The SITOP SEL1600 is a modular selectivity module 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 power supply to other circuits. Its modular expandability from 4 to 40 outputs combines with bidirectional IO-Link for remote parameterization and diagnosis. Select from two module options:
Streamline integration via IO-Link or common signaling contact with proven IO technology for reading/writing with high EMC.
Safely disconnect faulty load circuits and reaction-free power supply to other load circuits.
The SITOP SEL1600 is expandable to max. 40 outputs. You can also individually select the response threshold from 0.5 to 10 A for each output.
Selectively parameterize and monitor outputs via IO-Link remotely or via a display on-site.
Supply SITOP SEL1600 with a standard power supply with side-by-side mounting without lateral installation clearances to minimize its footprint in the control cabinet.
SITOP SEL1600 and SITOP PSU8400 use the same design, enabling simple device connection using a connection bracket for power and a flat ribbon cable for data.
