PHOENIX CONTACT
The value for the power dissipation of the housing is specified in every terminal-specific data
sheet.
The power dissipation of the housing for the specified terminal is 2.7 W within the operating
temperature range of -25°C to +55°C. The calculated power dissipation for the electronics
therefore does not exceed the permissible upper limit.
Even with the maximum permissible load current (0.5 A per channel), the upper limit of
2.7 W is not exceeded within the permissible temperature range of
-25 °C to +55 °C.
