TXA304 Binary Input Module

Type: Hager TXA304 Binary inputs

Bus System: KNX

Power supply: system voltage 30 V DC

Inputs: 4

Degree of protection: IP20

Construction: DIN sheets

Independent binary inputs 230 V AC with its own neutral connection (possibility of various FI circuits), for connecting 230 V AC contacts, eg: conventional switches / pushbuttons, timers, windshields, twilight switches. 230 V AC signal contacts in general. Quiescent current per input 10 mA.

Features:
Switching on / off (sending also with time delay and periodic sending)
Dimming (dimming with 1 and 2 buttons), UP / DOWN (control with 1 and 2 buttons, also move as long as it is pressed). Transmitter of values for temperature, brightness, dimming value in%. 
Alarm input with periodic sending and signal selection. Two-channel input mode for switching and recalling values: function 1 by short keystroke, function 2 by long keystroke. Selecting the setpoint for the heating function. Blocking function. Forced control. Call timer. Call up a scene with a button (1 scene) or a switch (2 scenes). Manual control (can be locked permanently or temporarily). Simulation of each input state using the manual control button. The input LED can be parameterized. It is possible to define the behavior during bus voltage initialization and recovery. Power failure monitoring.

Application software:
TL304C (pre TXA304)
TL310A (pre TXA310)
