The function of sensing the current of each relay output by the “true RMS” method.
(RMS = root of the square value)
The device does not require an additional power supply and is immediately ready for use after applying the bus voltage. 20A relay for each of the 8 channels. The front panel is removable, which allows the operator to manually operate the switch even when the knx is disconnected (only after disconnecting the power supply to the load and disconnecting the mains voltage).
Logical properties:
8 logical blocks: simple expressions with logical or threshold operators or complex expressions with algebraic and conditional operators. Relay groups (up to 8) can be combined with blocking logic for special functions.
