4940245 HM 12 T KNX Heating actuator 12x24V-240VAC

Type: Theben 4940245 HM 12 T KNX Heating actuator 12x24V-240VAC

EAN: 4003468490761

Bus System: KNX (TP)

Mounting: DIN rail

12-fold heating drive FIX2. With 12 temperature controllers (P/PI) for heating and cooling. For controlling thermal actuators 24 V - 240 V AC in 4 groups with 3 outputs and 450 mA each. (Due to the behavior of the servo motors when switched on, we recommend not to exceed the maximum load of 3x1 servo drives 24 V AC or 3x5 servo drives 230 V AC). Resistant to short circuit and overvoltage. Optional permanent or switching action value. The valve protection function can be deactivated. With modes: comfort, standby, night, as well as frost/overheat protection. Transition to summer mode possible. LED display of switching status for each channel.
