Safety Relay
Version ELMON rail 37-726 ELMON rail 38-726
Safety-related inputs 2x 2x
Safety-related outputs 1x 2x
(2nd contact internally
bridged to +24 V)
Auxiliary outputs 1x 2x
5. Application examples
Circuit diagram in zero-potential state. Sensor not actuated.
The auxiliary relay output is used for visualising the switching state of the safety contact edge.
5.1 Example of use
ELMON rail 37-726
Safety-related monitoring of two sensor
circuits for bringing a drive with automatic
restart to a standstill with an ELMON rail
37-726. The auxiliary output is connected
to the PLC controller of the plant (e.g. for
visualisation).
5.2 Example of use
ELMON rail 38-726
Safety related monitoring of two sensor
circuits with start release via start button
with one channel of an ELMON rail 38-726.
For functional test of the forcibly actuated
contactor K1, its normally closed contacts
are connected to the start circuit (Z1 Z2).
