Safety Time Control Device SCB
Figure14:
Dual-channel emer-
gency stop circuit with
PNP semiconductor
outputs / OSSD out-
puts with seüerate
cross circuit detection.
For safety applications
up to PL e, Cat. 4,
SIL 3.
Figure 15:
Connection of the power
supply to the terminals A1 and
A2.
Figure 16:
Connection to switching loads at
safety contacts (Exemplary contact
configuration. Differing according
to device type. Switching voltage
"L" according to tech. data).
Inductive loads at the outputs and
contacts must have sufficient
protective circuitry, e.g. a free-
wheeling diode.
