5.8.6 24 VDC for External Use
General
The robot has a 24VDC supply available for customer connections called 24V I/O.
The supply is a general purpose supply which can be used to supply digital inputs
and outputs or other external units connected to the robot control cabinet.
Specifications
24V I/O is not galvanically separated from the rest of the controller voltages
Connection
Connections are available on circuit board PDB, connector X18 as shown below.
For location of the PDB board, see ’Controller Connections Overview’ on page 42.

External 24 VDC Supply
The internal supply can not be used in the following cases:
• When more power is needed than can be supplied by the internal supply.
• When the emergency stop circuits are to be independent of whether or not the
robot is powered.
• When there is a risk that major interferences can be carried over into the internal
24V supply.
An external supply is recommended to make use of the advantages offered by the
galvanic insulation on the I/O units.
The neutral wire in the external supply must be connected in such a way to prevent
the maximum permitted potential difference in the chassis earth from being
