The CLS-08T-2P Light Control Unit is a convenient solution for lighting controls with standardised 0(1)-10V interface for source and sink operation. The interface can be loaded with 20mA and is used for direct connection of dimmable fluorescent lamps with ECG 1-10V or LV halogen lamps with 1-10V transformer. A hybrid relay switching output with a load capacity of 230V, 1500VA, 6.5A is also available for the analog output. This is optimised for ECG loads by a special zero-crossing circuit and guarantees a safe mains circuit for dimming. By using additional power dimmers, a wide variety of applications and power classes can be realised. The basis of the control unit is a digital, future-oriented multiprocessor technology, which guarantees easy to operate functions and extremely safe operation.

With this control unit, the following functions are available for a dimming circuit:

  • I/O
  • Brighter, dims brighter as long as the button is pressed
  • Darker, dims darker as long as the button is pressed
  • Preset 1 - calling a fixed dimming position (DIA value)
  • Preset 2 - calling a fixed dimming position (DIA value)
  • Central on - defined switch on
  • Central off - defined switch off
  • Signal-on

Up to 8 buttons/contacts (24V) and 5 feedback signals (24V) can be connected to the control unit. 4 potentiometers are available for setting the "switch-on light value" (Einschaltwert), value "Preset 1" and "Preset 2" and the "fade time" (Blendzeit).

Functions can be called up either via a pushbutton panel, single buttons or potential-free contacts.

Thanks to its universal logic, the Lighting Control Unit can be used for different operating modes. These can also be combined with each other at any time.

Variant 1 - I/O

This variant is available for fixed value settings (e.g. exhibition lighting, basic lighting,...). When switching on (I/O button), the light value set on the potentiometer (switch-on light value) is called up and held. By pressing the I/O button again, the lighting is switched off.

Variant 2 - I/O, Brighter, Darker

When switching on (I/O button), the light value set on the potentiometer (switch-on light value) is called up and held. The "brighter" and "darker" buttons are used to change the brightness in the respective dimming direction for the duration of the button press. By pressing the I/O button again, the lighting is switched off.

Variant 3 - I/O, Brighter, Darker, Preset 1, Preset 2

As described before and additionally 2 presets (fixed values or DIA values) are available. By pressing the corresponding "preset" button the brightness value set at the potentiometer "Preset 1" or "Preset 2" is called up.

Central switching

Higher-level control interventions are possible via the central on (100%) and central off functions. Thus several groups can be switched on or off at the same time (e.g. central control panel at the gatekeeper). A 24V output is available to indicate whether the lighting is still on.

Setting fade time (dimming speed)

With the potentiometer "Blendzeit" the fade time can be adjusted within the range of 0-30 seconds. The dimming time from 0 to 100% is defined as the fade time. A typical default value here is 5 seconds. The dimming with the function buttons always takes place with the set fade time. The output of the analog value when switching on or off takes place without delay.
