NOTICE
The UL testing only includes fire and shock tests.
Tab. 12.5:
Technical data of the electronic safety-related switching outputs (OSSDs) on the receiver
Safety-related PNP transistor out-
puts (short-circuit monitored,
cross-circuit monitored)
Minimum

Switching voltage high active (U

Residual current
500 µA
In the event of a failure (if the 0 V ca-
ble is interrupted), each of the outputs
behaves as a 120 kΩ resistor to U
v
. A
downstream safety PLC must not de-
tect this as a logical “1”.
Load capacity
30 nF
Load inductivity
500 mH
Permissible wire resistance for load
< 20 Ω
Note the additional restrictions due to
cable length and load current.

Permissible cable length between re-
ceiver and load

OSSD restart delay time after beam
interruption
100 ms
(1*) The outputs are tested cyclically (brief low or high switching). When selecting the downstream control
elements, make sure that with the parameters specified above, the test pulses do not lead to a shutdown.
