5.3.6 Output expansion 3SK1213
5.3.6.1 Device features
MLFB:
3SK1213-xAB40 24 V DC
3SK1213-xAJ20 115 V AC
3SK1213-xAL20 230 V AC
(x) 1 = screw-type terminal; 2 = spring-loaded terminal
Supply:
24 V DC:
● An SELV / PELV power supply must be used for the infeed
115 V AC and 230 V AC
● Direct line supply connection L/N
Device properties:
● Slide switch for selecting the activation type (time-delayed / instantaneous)*
● 1 LED for status display
● 3 enabling circuits (safe circuits, NO contacts)
● 1 NC circuit as feedback contact for output expansion 3SK1213 for the up-circuit basic
unit
● 3ZY device connectors*
● Enclosure width 90 mm
● Removable terminals
* For 24 V DC variant only
When using 3ZY device connectors
The output expansion 3SK1213 must always be terminated with a device termination
connector, type 2, set for enclosures > 45 mm (3ZY1212-0FA01). Expansion on the right-
hand side is then no longer possible.
