MI04

For connecting four conventional push-buttons or dry contacts. Internally generates a SELV signal voltage, electrically isolated from the bus. With integrated bus coupler and plug-in screw terminals. The bus is connected via a connecting terminal; a data rail is not necessary. The input voltage level is shown on each input with a yellow LED. A green LED indicates that the device is ready for operation once the application has been loaded. KNX software functions: switching, dimming or Venetian blind control using 1 or 2 inputs. Positioning control for Venetian blind control (8-bit). Pulse edge with 1-, 2-, 4- or 8-bit telegrams. Differentiation between short and long activation. Initialisation telegram. Cyclical transmission. Pulse edge with 2-bype telegrams. 8-bit linear regulator. Disable function. Break/make contact. Debounce time. Inputs: 4; Contact voltage: max. 10V, timed; Contact current: max. 2 mA, pulsed; Cable length: max. 50 m; Contents: bus connecting terminal and cable cover.
