Data sheet
Intended Use
The PSR-PS40 SIL coupling relay can be used for power
adaptation and electrical isolation in high and low-demand
applications up to SIL3 according to IEC61508 as well as
EN61511.
Using this module, circuits are interrupted in a safety-ori-
ented manner.
The category 3 device is designed for installation in zone 2
potentially explosive areas.
The safety relay is equipped with an enabling current path
that drops without delay corresponding to stop category 0 in
accordance with EN60204-1.
By filtering the controller test pulses, premature failure of the
safety relays is prevented.
The module performs a selftest the moment it is switched on
and prevents the enable contacts from being closed in the
event of an error.
