DXR2.M18 6 8 x 6 = 48 18 4 6 70
Power for the Triac outputs must be reduced if the maximum load of 18 VA is required for AC
24V field supply on the DXR2.x18.
NOTE:
To calculate the total VA, add the Base Load + the number of Triacs + field supplies+ KNX PL-
Link devices.
This cannot exceed the maximum power consumption. See the
Wiring Guidelines for more
information.
