Floating Interlock and Relay contacts

Enhance the safety and control of the SM15K and SM3300 series power supplies with the Floating Interlock and Relay Contacts interface module. This module adds a floating interlock loop or 24 V enable input, allowing the power supply to be integrated into external safety circuits and system interlocks.

The module offers:

  • A floating interlock / 24 V enable input for safe system start-up and shutdown.

  • Four programmable relay contacts.

  • Relay control via Ethernet commands or by linking the relays to internal status signals of the power supply. 

  • Flexible use in automation and safety applications, for example cabinet door interlocks or hazard warning lights.

This pluggable interface card can be installed at any time for an effortless upgrade. For detailed specifications, refer to the data sheets below.
