The new generation of safety relays from IDEM
Single or Dual channel operation
The Viper Safety Relays range from
IDEM are designed to meet the latest safety standards and
offer enhanced LED diagnostics and simplified wiring. Applications include safety interloc
switches, emergency e-stop devices, door guard monitoring.
The Viper Safety Relays range includes output expansion units that can be directly wired to
SCR-73-i safety relay to increase the number of safety output contacts. The expansion modules
are available with either immediate or time-delayed output contacts.
The SCR-73-i internal logic uses force guided relays to achieve cross monitoring, this ensures
that a single fault does not lead to the loss of the safety function and that all faults are detected
at or before the next safety demand.
Monitored Manual or Auto Start/Reset
7 NC safety output contacts
3 NO Auxiliary output contacts
Contactor feedbac chec
Easy diagnosis of status via 6 LEDs
24Vac/dc operation
Up to PLe, SILCL 3, Category 4
45mm DIN rail mounting
Emergency stop and guard interloc
monitoring
Output expansion units available to
increase number of outputs.
Fun tional Des ription
When the control line inputs are closed and the start/reset condition
has been met the safety output contacts close.
The safety relay outputs open when the inputs are de-activated or if
there is a power failure. When dual channel inputs are used it is not
necessary to synchronise switching of the input channels.
When operating in the monitored manual reset configuration the
reset button must perform a ma e-then-brea action before the
safety relay will activate.
External device feedbac contacts can be monitored via the reset
loop.

• Installation should only be arried out by
ompetent and authorised personnel and in
a ordan e with the instru tions in this manual.
• Only make ele tri al onne tions when the devi e
is isolated from the main supply.
• If “Automati Start” is sele ted be aware that
safety output onta ts will swit h immediately
after the power supply is onne ted.
• Opening the devi e will void the warranty. Never
attempt to repair any devi e.
• Adhere to Safety Che ks.
• DO NOT DEFEAT, TAMPER, OR BYPASS THE
SAFETY FUNCTION. FAILURE TO DO SO CAN
RESULT IN DEATH OR SERIOUS INJURY.
• L'installation doit être effe tuée par un personnel
ompétent et autorisé et en onformité ave les
instru tions de e manuel.
• faites uniquement des onnexions éle triques lorsque
l'appareil est isolé de l'alimentation prin ipale.
• Si "Démarrage automatique" est séle tionné être ons ient
que les onta ts de sortie de sé urité passeront
immédiatement après l'alimentation est onne tée.
• Ouverture de l'appareil annule la garantie. Ne jamais tenter
de réparer tout appareil.
• Adhérer à des ontrôles de sé urité.
NE DÉFAITE PAS, SABOTAGE, OU DE CONTOURNER LA

ENTRAÎNER LA MORT OU DES BLESSURES GRAVES
Installation and Maintenan e Information Regarding UL 508
Installation should as per EN 60204-1 in addition to any local
regulations. The safety relay should be mounted inside a
cabinet enclosure and on a 35mm DIN rail according to DIN
EN 60715. No maintenance is required, there are no
serviceable parts. (Refer to Safety Chec s). The product is
designed to be a component of a customised safety
orientated control system. It is the responsibility of the user
to ensure the correct overall functionality of its systems and
machines. IDEM, its subsidiaries and affiliates, are not in a
position to guarantee all of the characteristics of a given
system or product not designed by IDEM.
