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

provide optimal safety and a
high degree of reliability on
