I I I I I Supply voltages:
The option card is supplied by the internal 24 V
DC supply of VLT 5000, but as the available power
is limited it can be necessary to use an external
24 V DC supply.
The 24 V DC supply of VLT 5000 can supply a total
of 420 mA including the load on the control card
(terminal 12, 13 and output 42 and 45).
The 5 V output on the option card is generated
from the 24 V supply. The maximum power on the
5 V side is 5 V * 280 mA = 1.4 W, this corresponds
to app. 60 mA on the 24 V side.
When an external 24 V DC voltage source is used
the internal 24 V supply from the control card must
be disconnected, this is done by opening
switch 1.1 and 1.5.

Each digital input on the option card takes 8 mA.
Each digital output on the option card can supply
up to 0.7 A (external 24V-supply) depending on the
load.
The load from the 24 V supply (internal or external)
can be calculated as follows:
8 mA * number of digital inputs
Load on digital outputs
(mk3 C, O1 – O8)
load on 5 V supply
(mk3 B/D, 5 V/com)
Load on control card
(24 V supply, terminal 12/13 and
outputs, terminal 42/45)
