Product Description
Application Description
Features
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.
Eaton’s ESR5 safety relays
provide optimal safety and a
high degree of reliability on
plant machinery. Applications
that meet the highest
safety requirements in
accordance with EN 954-1,
EN ISO 13849-1 up to PL e
and accordance with
IEC 62061 up to SILCL 3
can be realized with the
ESR5 safety relay.
●
Compatible with a wide
variety of safety devices:
●
●
●
●
●
●
●
Emergency stops
Rope pulls
Two-hand control stations
Light curtain (OSSD)
Gate enable device
Safety switches
●
●
●
●
Use for the highest
safety requirements in
accordance with EN 954-1
EN ISO 13849-1,
IEC 62061 and EC 61508
Suitable for the world
market with UL, cUL
certifications and TÜV
Rhineland functional
safety certifications
Applicable for EN 60204
stop categories 0 or 1
Plug-in screw terminals
for fast and fault-free
replacement
Multi-voltage versions
(24–230 Vac/Vdc) for a
flexible range of application
Delayed and non-delayed
contact expansions
accommodate a wide
variety of applications
