Universal switching and dimming module with extended functionality for DIN rail mounting

The LCN-HU Universal DIN rail mounted module is a sensor/actuator module for the LCN Bus system. It has three 0 -10V dc outputs for control of electronic ballasts which can also be connected for DSI or DALI applications. Additionally, two of the four outputs run parallel on electronic switch- dimmable outputs at 230V respectively. Furthermore, additional sensors and actuators can be connected through the LCN-HU’s T-, I- and P- ports. The internal operating programme can be freely parametrised using the LCN system software LCN-PRO.

Field of applications:

  • Theater standard high grade lighting control, sophisticated lighting effects and daylight dependent lighting control.
  • Simple RGBW control with electronic ballasts.
  • Control of solar shading and conservatories.
  • Individual room control: cooling, heating and ventilation.
  • Access control with IR remote control and transponders.
  • Automatic control with numerous timers and associated logical operations.
  • Hierarchical logical operations – authorisation.
  • Alarm systems with multiple zones and complex requirements
  • Associated logical operations across installation/facility boundaries including: lighting‹-› solar shading ‹-› alarm ‹-› entry restriction, etc.
  • High performance through cost effective multiple application of sensors and actuators.

All functions can used independently and are also available to be used simultaneously.


230 V PSU 50/60 Hz (110 V version available).

Two 230 V 500 VA zero crossing electronic switching or dimming outputs (phase cut-on).

Four analogue 0 – 10 V outputs, switchable to DALI or DSI.

T-Port for connection of up to eight keys via key converter or A/D converter (LCN-AD2), etc.

I-Port for combined connection of LCN-RR (IR-remote-control receiver), LCN-TS (temperature sensor), LCN-BMI (motion detector), LCN-ULT (transponder reader), LCN-GTxD (Glas Touch-Keypad) etc.

P-Port connection as digital in-/output for further peripheries such as relays LCN-R6H, LCN-R4M2H or LCN-R2H, LCN-BS4 (current sensor), etc.
