Decentralized input module (2/4 contacts)

Execution: 2 inputs
  • Input module to directly connect standard push buttons to the bus.
  • Fits into a standard flush-mount switch box.
  • Can be connected to 2 or 4 potential-free contacts (e.g., push buttons) and 2 or 4 LEDs.
Technical info

The INPx can connect 2 or 4 potential-free contacts (e.g. push buttons) and 2 or 4 LEDs. These modules fit in a switch box and are an ideal solution for connecting standard push buttons directly to the bus.

Frequently Asked Questions

  • How do you read an existing configuration?

    This is a completely different procedure depending on the type of controller.

    • For the CTD controllers this goes as follows:

    In the SMIII via "File" or "Utilities / Setup / SD card", click on "Recover QDB from SD".

    After confirmation you choose the name and location where the file should be saved. The zipped QDB file is then read from the SD card of the CTD and saved. With a positive answer to the question "Unzip and open restored QDB?", All data will then be immediately available. If the data you were still working on was not sent or saved, you will first receive a notification to do so.

     

    • For a CTL controller follow the following procedure:

    Because this controller does not yet have a large memory, only limited data can be recovered. Ao the names are abbreviated to 12 characters and serial numbers are not stored anywhere.

    The first step is therefore to type in ALL serial numbers via SMII via "File / Modules". These 6-digit serial numbers can be found on every module (DIN rail, switch, detector, etc.). For the SWC0x switches, an extra option was provided to have them send their serial number via “Search for modules”.

    When you then click on the "down arrow", you can read all this limited information.

  • Always use the latest software for configuration.

    It is always recommended to use the most recent version. This version supports the newest modules and resolves all known bugs.

    If, for example, you enter a serial number and the correct module information does not appear, you are likely not working with the most recent software.

    A newer version will always be able to open the older files (.QDB) without data loss.

    The latest version of the System Manager software, along with the user manual and version history, can be found in the knowledge center.

Technical info for installers

  • Function Description

    The maximum length of the cable between the INP02 or the INP04 and the contacts connected to it is 20 meters. 

    An INP02 can control 2 outputs, 2 modes, or 2 x 16 modes (via the sequencer function).

    The 2 low-voltage LEDs that can be connected to an INP02 indicate the status of the selected mode for each input.  

    Each module has a unique serial number (6 digits). Based on this serial number, the module can be programmed via the Qbus software.

General

  • Safety Regulations

    Read the full manual before installing the module and activating the system. 

     WARNING

    • The module must be installed, commissioned, and maintained by a certified electrical installer in compliance with the applicable legal regulations of the country.
    • Never connect AC or DC power to a potential-free input. This will damage the input module.
    • The module must not be opened. The warranty will be void if the module is opened!

Installation and cabling

  • Power Supply

    ALWAYS USE POTENTIAL-FREE CONTACTS. INTERRUPT THE POWER SUPPLY TO THE MODULE BEFORE CONNECTING OR DISCONNECTING THE MODULE.

    The INP02 and INP04 are powered via the bus.

  • Load

    Low-voltage LEDs (2mA without ballast) can be connected to the LED outputs of the INP02 and INP04. 

  • Inputs

    Connect the inputs as shown on the connection diagram. Remove approximately 7mm insulation from the cable and insert the cable into the terminals I1-I4. Both solid and stranded wire can be used; for stranded wire, a screwdriver should be pressed on the terminal when inserting the wire. 

    The maximum thickness of the wire is 0.5 mm2. By pressing on the top of the terminal with a screwdriver, the wires can be pulled out from the terminals. 

    The cable connecting the contacts with the INP04 or INP02 should not exceed 20 meters in length.

     

  • BUS connection

    It is recommended to use the Qbus cable or any other cable with a minimum of 2 conductors of 1mm² as the bus cable. The green shielded EIB cable can also be used if the conductors are paired to achieve a minimum cross-section of 2 x 1mm².

    INP02

    P49 INP02

    INP04

    P49 INP04

Each modules has an unique serial number. By this number the System Manager recognizes the modules.

This is completely explained in our knowledge center.

 

This module can be used to connect an ordinary switch (without integrated Qbus PCB) or external contacts such as a solar/wind detector, a motion detector, door switches, magnetic contacts for doors and windows, etc.

2 or 4 input switches can be connected, which must be potential-free.

Each module has a unique serial number for programming. After entering the serial number, the following window will appear:

Qbus System Manager III Manual Update 04 2025 pdf image 250

The input contacts can be selected and set with the system manager as shown below.
- Push button = when you connect a push button to the input
- Normally open = contact open when not energized (for long contacts - see below)
- Normally closed = contact closed when not energized (for long contacts - see below)
- Switch = when you connect a switch to the input (2 positions – on & off).

ATTENTION: Always use Normal Open or Normal Closed when connecting inputs that give long contacts (e.g. magnetic contact for window, motion detector, smoke detector, ...). These inputs maintain the same state for a longer period of time and only activate the I/O when that state changes. If you use "push button" for those inputs, the bus will continuously send the status to the controller, resulting in poor communication. Only use push buttons for short contacts (= ordinary push buttons).

One module can control up to 4 I/O’s, 4 scenes or 4x16 scenes via the sequencer function. The I/O’s can also be activated from the system manager using the Test key in the programming window. The instantaneous status of the I/O’s can be consulted by pressing the "Read values" key in the programming window of the INP0x module.
