Two channels connection with antivalent contacts
In the example the R1 contact must be closed and the R2 contact must be opened before the
safety relay can be set in active mode. Switching one or both of the contacts inactivates the
safety relay. If T1/T2 are used gives short circuit detection.
Both contacts must switch from their initial position and back again before the outputs can be
activated.
Two channels connection with antivalent contacts, +24 VDC static signal
Two channels connection with antivalent contacts from T1/T2

Two channels OSSD connection
Safety devices with dual OSSD outputs can be connected to R1 and R2. Short-circuit between
the signals and to 24V DC are detected by the safety device from where the OSSD-signal
originates.
