Safety Function with Mirror Contacts
EN 60947-4-1 certification for mirror contact mechanisms has
been obtained by using a combination of a relay and auxiliary
contact blocks (5 VDC, 1 mA), enabling application in feedback
circuits of safety circuits.
Application Example: General Safety Circuit
G9SA-301 (24-V AC/DC) (two limit switch input channels with
manual reset)

Mirror Contact Mechanism
By combining a Relay with an auxiliary contact block, all NC
contacts of the auxiliary contact block will satisfy an impulse
withstand voltage of 2.5 kV or higher or maintain a gap of 0.5 mm
or greater when the coil is de-energized even if at least one NO
contact (main contact) of the Relay is welded.
