Product Description
3
Safety relays are intended to
reliably monitor the signals
3
from safety devices at all
times and switch off quickly
3
and reliably in an emergency.
Single-channel and dual
channel versions are available
3
for the construction of safety
applications. The internal
3
logic of the safety relays
monitors the safety circuits
3
(emergency stop, guard door,
and so on) and activates the
enable paths in a fault-free
3
condition. Upon actuation of
the safety device or in the
3
even of a fault, the enable
paths are switched off. Any
3
faults that occur in the control
circuit, such as ground fault,
3
cross connection fault or wire
breakage are also detected.
