Safety switching, expansion unit and time delay module
The safety switching unit, its corresponding expansion unit and
the time delay modules are main elements of a safety switching
system in the switching cabinet; they bear the VGB test mark.
They serve to implement, for example, functions such as
• Emergency Off,
• Drive enable,
• Guard interlock,
to prevent hazards for personnel and machines.
The safety switching unit is self-monitoring and ensures that
machinery can only start if there are no faults, or it shuts down
in the event of a fault.
In conjunction with the safety switching unit, the time-delay modules
allow a defined Off-delay which is preset and individually
adjustable.
The safety switching units can be used for all equipment
covered by the regulations of DIN EN 60 204 Part 1.
The modules are easily fitted by snap-mounting on a
35 x 15 mm DIN rail to DIN EN 50 022.
