Switch Actuator with Current Detection, 2-fold, 16/20 AX, C-Load, MDRC
Switch Actuator SA/S 22.214.171.124, 16/20 A is a modular installation device in ProM design for installation in the distribution board. It is especially suitable for switching loads with high peak inrush currents such as lighting equipment with compensation capacitors or fluorescent lamp loads (AX) to EN 60 669.
The Switch Actuators feature one load current detection per output. The maximum load current per output is 20 A.
Manual actuation of the Switch Actuator is possible using a button. This simultaneously indicates the contact position.
The Switch Actuator can switch 2 independent electrical loads via floating contacts. The connection of the outputs is implemented using combo-head screw terminals. Each output is controlled separately via KNX.
The device does not require an additional power supply and is ready for immediate use, after the bus voltage has been applied.
The Switch Actuator is parameterized via ETS. Connection to KNX is implemented using the bus connection terminal on the front.
The following functions can be set individually for each output:
- Time and ON/OFF delay functions
- Staircase lighting function with warning and modifiable staircase lighting time
- Recall of scenes/presets via 8/1 bit commands
- Logical functions AND, OR, XOR, GATE function
- Status messages
- Forced operation and safety functions
- Response to threshold values
- Control of electro-thermal valve drives
- Selection of the default state on bus voltage failure and recovery
- Output inversion
- Load current detection value with parameterizable response to two current threshold values.
