Pluggable interface relays CR-U
Universal relays
Data sheet
Application
Interface relays are electromechanic and electronic input and output modules for electrical isolation,
levelling, noise suppression or signal amplifi cation between control unit and process.
Operating mode
When power supply is applied, the output contacts get closed. When control supply voltage is switched
off, the contacts fall back into their starting position. Manual operation and locking of the output relays is
possible via the integrated test button.
