■ Overview
The SITOP expansion modules offer further functions:
The signaling module
can be snapped onto the side of the
6EP1 ...-3BA00 basic unit; with floating signaling contacts
"Output voltage OK" and "Ready OK"; with signal input for remote
ON/OFF switching of the basic unit.
The redundancy module
uses diodes to disconnect the basic
units from one another so that a redundant 24 V power supply
can be constructed.
The two SITOP PSE200U selectivity modules
and the
SITOP select diagnostics module
are used in combination with
24 V power supplies for distributing the load current among up
to 4 current branches per module and for monitoring the individ-
ual partial currents. Overloads or short-circuits in individual
branches are selectively switched off and the remaining load
current paths remain unaffected. Individually adjustable rated
current, LED, group alarm contact, standard rail mounting.
The buffer module
bridges mains interruptions in the range of
seconds. Buffer time 200 ms at 40 A, up to 1.6 s at 5 A load cur-
rent. Multiplication possible through parallel circuit, maximum
buffer time 10 s.
