The 16A series switching actuator modules are modular installation devices with 4-circuits, 8-circuits and 12-circuits outputs. EIB bus terminals are connected to EIB/KNX system, and ETS software (version ETS4.0 or above) is used for physical address allocation and parameter setting.

The maximum load current for output of each 16A series switching actuator module is 16A, including 4, 8 and 12 intelligent relays. Each circuit can independently control the switch of 2000W lamps. The above is only for resistive load lamps, the actual use of 80% of the power to drive the resistive load will be more appropriate. To the inductive load and capacitive load, especially in the case of multiple lamps in parallel, the loads that can be carried will be reduced. Although the power is unchanged, the inrush transient current will increase, easy to melt relay contact, so for the inductive load and capacitive load, it is advisable to use 1/5 or 1/6 of the maximum current commonly, even some inferior LED lamp loads require 1/8 of the maximum current. 16A series switching actuator module with manual control buttons, LED indicates the status of each circuit switch.
