The new generation of safety relays from IDE
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 SCR-31P-i is design to be
compatible with OSSD devices.(e.g. Light Curtains)
The Viper Safety Relays range includes output expansion units that can be directly wired to SCR-
21-i / SCR-31-i / SCR-31P-i safety relays to increase the number of safety output contacts. The
expansion modules are available with either immediate or time-delayed output contacts.
The SCR-21-i / SCR-31-i / SCR-31P-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
Up to 3 Safety output contacts
1 Auxiliary output contact
(Depending on model No.)
Contactor feedbac chec
Easy diagnosis of status via 6 LEDs
Up to PLe, SILCL 3, Category 4
22.5mm DIN rail mounting
24Vac/dc operation
Emergency stop and guard interloc
monitoring
Output expansion units available to
increase number of outputs.
Functional Description
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 and aintenance 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.

Safety Checks.
1. Ensure the appropriate safety level is achieved for the application function.
2. The safety functions must be tested regularly. For applications were infrequent use is foreseeable, the system must have a manual
function test. At least once per month for PLe Cat3/4 or once per year for PLd Cat3 (ISO13849-1 / ISO14119).
