Power Supply and Cooling Requirements
A quick guide for power consumption to be used in a preliminary phase of a project
work or whenever you need estimated figures is provided in Table 31.
Table 31. Estimated System Power Consumption
S800 I/O Station

Base cluster, redundant FCIs (2), with six (6) I/O Modules 1.0
Base cluster, redundant FCIs (2), with twelve (12) I/O Modules 1.5
Base cluster, redundant FCIs (2), with six (6) pairs of redundant
I/O Modules

The estimates are based on fully loaded I/O stations with a mixed configuration
of DI/DO and AI/AO.
Only power distributed via the ModuleBus are included. External 24 V connected
directly to the I/O modules for external loads and transmitters are not included.
When using AO820 and/or DO820/DO821, these load figures may be exceeded
and a load calculation can be useful to do, see Table 32.
