Connection with M12 adapter
With the adaptor type FBA−2−M12−5POL−RK (reverse key"
coded), you can connect the SFC−LACI to the field bus using
an M12 plug connector. You can disconnect the M12 adapter
from the SFC−LACI without interrupting the bus cable (T−Tap
function).
Connection to the field bus is made with a 5−pin M12 plug
with PG9 screw connector.
Use the second connection socket
for the continuation of the field bus.
