TX4IWL: wireless transmitter module
TX4IWL is a wireless battery-powered transmitter module, compatible both with Domino and Contatto bus, and it uses the ENOCEAN wireless technology.
This transmitter module can be thus indifferently used with Domino DFWRX or Contatto ModWRX receivers.
TX4IWL module features 4 digital inputs for external con-tacts: at every input change, the module performs a trans-mission; in addition, the module executes a cyclic transmis-sion every 17 minutes about, regardless of changes of in-puts, so that to always ensure the alignment between the field and the receiver.
TX4IWL module has been developed for all those applica-tions requiring to transmit in wireless mode the status of some contacts (e.g. end-point switches or similar devices) that are not integrated pushbutton assemblies; this module is therefore suitable in all cases when the conversion of Installation hints

Wiring diagram and installation
TX4IWL module features a red LED that is visible through the semitransparent cover; this LED beams a short light TX4IWL module, for its operation, only requires the battery insertion and the connection of its inputs. The follow wiring diagram shows the proper connections.

Place in the correct way the gasket on the cover and apply it to the the bottom of the module: pay attention that the re-movable terminal block be on the opposite side of the cable bushing.
Technical characteristics
By Lithium Battery (Lithium/Manganese Dioxide, Li/MnO), 3V, 1500mAh The bottom of the case must be fixed on the wall (vertical or horizontal) by two screws (not provided). Introduce the multicore cable through the cable bushing: pay attention to the coupling between them in order to as- sure the water-proof characteristic of the module. After that connect the wires to the 5-way removable terminal block as 3 years about, depending on the using and on the self-dis-charging of the used battery Outline dimensions
Insert the removable terminal block into the related male connector. Insert the battery, taking attention to the polarity shown on the battery holder.
