Heat Rise De-rating
The HC900 is rated to operate at 60
o
C. However, for maximum reliability, the following guidelines should
be observed for applications above 52
o
C.
1.
Locate lower-power modules (Analog Input, Contact Input, etc) beside the Controller/Scanner Module,
and keep higher-power modules (AC Output, AC Input, etc) away from it. For power consumption of
each module, see Table 4.
2.
For 240 Vac applications and temperatures above 56
o
C, or 264Vac, 52
o
C, de-rate the number of ON
inputs per AC input module. (See AC Input de-rating data, see Figure 27.)
3.
Limit the number of Analog Output modules to a maximum of 10 per rack. (see Figure 28)
