Wieland Electric's new range
of safety relays are only
22.5mm wide and have been
designed for universal use.
The SNO 4083KM relays are suitable for most mechanical engineering applications, particularly special machine engineering or for smaller serial machines.
Their safety functions range from conventional emergency stop and safety door monitoring and monitoring of electrosensitive protective equipment (ESPE) - type 4 (safety light curtain) - to the monitoring of pressure mats or coded magnet switches with open/close contact pairs.
Additional functions include a selective automatic or manual monitored restart of the safety function, synchronous time monitoring of 0.5 or 1.5 seconds for all two-channel applications, and the integrated Monoflop function for higher device availability.
The smart diagnosis of the device operating state helps reduce downtime and supports economical machine operation, as well as the high operating capacity of the contacts and the wide temperature operating range of -25 ºC to 65 ºC. The SNO 4083KM safety relays are used for conventional safety tasks in mechanical and system engineering and applications in lift engineering (according to EN 81-1) or in controls for industrial combustion plants (according to EN 50156-1).
