3.1.4 Connection of extra 24 V power supply
Internal power supply
(A)
may only be used to supply factory-installed modules.
In case of a greater power consumption than 0.8 A from the loop module
(B)
, an extra power supply
(C)
must be
used and possibly
(D)
. The A5 minus terminal is connected in parallel (terminal A5 to A5).
+24 V max. 2.1 A
+24 V max. 2.1 A
+24 V max. 0.8 A
The power supply must be connected to the controller using a multi-conductor cable. Number of conductors in
the multi-conductor cable is determined by the connected products.
The multi-conductor cable is used for input and output signals from the connected products and to the minus
wire of the power supply.
