Power Supply Connections - ABB S800 I/O Manual

Section 3 Configuration

Power Supply Connections

The FCI requires 24 V d.c. (19.2 - 30 V) with a maximum current requirement of
1.4 Ampere. See
Figure 14. FCI Power Supply Connections
The incoming power can then be distributed to other FCIs or the I/O modules if
desired. Refer to S800 I/O Getting Started (3BSE020923*) for power supply
connection diagrams.
Power connections can accept 0.25 - 2.5 mm
