Note (1): absolute encoder and supply used exclusively in 24V.
Note (2): normal conditions of use: one active auxiliary input per channel (under 24V).
Note (3): "worst" case and extreme conditions: all auxiliary inputs active (under 30 V).
This module has a mini internal ventilator, which enables good working order in all temperatures. The ventilator is started up when necessary by the module’s internal temperature sensor (triggered at an external temp. of 45 °C).
It is possible to use external ventilation blocks (TSX FAN••), if the conditions around the module surpass the above parameters.
