UP 220/21 - Pushbutton interface 2 x potential-free contact, output for LED control
Product SKU: 5WG12202AB21
- The push button interface is a binary input and output device for installation in in-wall boxes (Æ 60 mm, depth: 40 mm).
- Each of the two channels may be used either as an input for potential-free switch / push button contacts or as an output for control of a light emitting diode (LED).
- The required scanning / control voltage is provided by the push button interface (requires no additional power supply).
- For example, up to 2 switches/push buttons with one potential-free contact each or one 2-fold push button with two potential-free contacts may be connected to a push button interface.
- The connection is carried out via a cable set which is permanently connected to the push button interface.
- The connecting cables between switches/push buttons and the push button interface may be extended up to 10 m. It must be ensured that twisted cable pairs are used.
- Commands can be given to actuators via the connected switches/push buttons, e.g. for defined switching on/off, for dimming fluorescent lamps or for raising/lowering venetian blinds and adjusting the louvres.
- Each channel, which is configured as an output, can drive an output current of up to 2mA for controlling a light emitting diode (LED).
- With the ETS the application program is selected, its parameters and addresses are assigned appropriately, and downloaded to the push button interface.
