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 control supply voltage 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.
