Description of fan modules
TSX FAN
pp
P
fan modules installed above the racks of Premium PLCs provide
forced air convection, in order to maintain an even ambient temperature inside the
enclosure and to eliminate any hot spots that may exist.
Fan modules are required when the ambient temperature is between 60 °C and
70
°C (forced ventilation enables the ambient temperature in the enclosure to be
lowered by 10 °C)

Three types of fan module are available: 24 V

According to the modularity of the racks used:
b
One fan module for a 4 or 6 position rack
b
Two fan modules for an 8 position rack
b
Three fan modules for a 12 position rack
TSX FAN

P
fan modules comprise:
1
A connection terminal block for power supply to the fan module, the internal
temperature probe and the associated LED or preactuator
2
An earth terminal
3
Two mounting holes for the fan module
4
Shuttered air outlets

For an ambient temperature between 25 °C and 60 °C, the use of fan modules increases the
MTBF.
