(

For applications that are sensitive to unintended stopping, the
ABL 8
range of
Function modules offers a solution comprising:
b
Electronic switch mode power supply and Buffer module for holding times t2 up to
two seconds
b
Electronic switch mode power supply, Battery control module and Battery module
for holding times t2 of between two seconds and a few hours
These solutions are used to supply voltage after loss of the line supply, thus enabling
saving of current values or fallback of some actuators supplied with 24 V
c
.
The table below indicates the possible holding times according to the equipment
combinations and the current required.

Note:
Several Buffer modules (up to a maximum of three) can be connected in parallel to
increase the immunity time. The times given in the table above (boxes marked 1) should be
multiplied by the number of modules used (2 or 3).
