Applications
Output expansion for safety relay modules and safety controllers
Contacts of a force guided relay are forced to open and
close by a guide connected to the armature.
Due to requirements of standard EN50205, a force guided
relay has independent NO and NC contacts. If a NO con-
tact welds, a NC contact will not close even when the relay
coil is turned off (de-energized) and must maintain a gap of
at least 0.5 mm. Furthermore, if a NC contact welds, a NO
contact will not close when the relay is turned on (ener-
gized) and must maintain a gap of at least 0.5 mm.
(General-purpose relays do not have the above characteristics.)
What is a force guided relay?
Relays used in safety circuits to detect failures such as contact welding and damage to the
contact spring.

Force Guided Relays
Force guided relays are used in safety circuits in combination with in-
terlock switches, light curtains, and emergency stop switches to control
outputs.
They can also be used to expand outputs for safety relay modules and
safety controllers.
