Leuze electronic MLC 520 - Dimensions, Weight, Response Time

Technical data
Leuze electronic MLC 520 54
Safety-related PNP transistor outputs
(short-circuit monitored, cross-circuit
monitored)
Minimum Typical Maximum
Residual current <2µA 200µA
In the event of a failure (if the
0V cable is interrupted), each of
the outputs behaves as a 120kΩ
resistor to U
v
. A downstream
safety PLC must not detect this
as a logical “1”.
Load capacity 0.3µF
Load inductivity 2H
Permissible wire resistance for load <200Ω
Note the additional restrictions
due to cable length and load cur-
rent.
Permissible wire cross section 0.25mm
2
Permissible cable length between receiver
and load
100m
Test pulse width 60μs 340μs
Test pulse distance (5ms) 60 ms
OSSD restart delay time after beam inter-
ruption
100ms
NOTICE
The safety-related transistor outputs perform the spark extinction. With transistor outputs, it is
therefore neither necessary nor permitted to use the spark extinction circuits recommended by
contactor or valve manufacturers (RC elements, varistors or recovery diodes), since these con-
siderably extend the decay times of inductive switching elements.
