The LED Dimmer was developed for controlling 4 LED lights with fixed voltage connection (integrated current regulation in the LEDs), e.g. LED strips. This makes it possible to control the brightness of the LEDs between 0 and 100% absolutely flicker-free with a dimming resolution of 16 bit (internal resolution in ISYGLT operation). The LED Dimmer can be set from speed calculation to absolute time calculation by parameterisation per channel. All imaginable control tasks, from individual light dimming to the use for complex light and colour scenarios, can be easily implemented.
The LED Dimmer can optionally be operated on the ISYGLT BUS or DMX512 BUS.
The regular DMX GND connector on PIN 1 is not required and therefore not connected.
The following functions can be performed independently by the LED Dimmer:
| Operating voltage | 10V, 12V or 24V for the supply of the LEDs depending on type |
| Emergency input | 10-24V DC |
| Mains fuse | max. 16A at Umax 24V DC |

4 circuits each with maximum 24V / 3.0 A / max. 72W per channel NPN switching (- control) Back-up fuse max. 16A, external power supply unit required |
| Power loss | approx. 0.1W standby |

DIP switches 4 to 10 are used to set the DMX address. The set address, multiplied by 4 and added by 1, corresponds to the first of 4 consecutive DMX addresses:
- Address 0, 0000000 = DMX 1, 2, 3 and 4
- Address 1, 0000001 = DMX 5, 6, 7 and 8
- Address 127, 1111111 = DMX 509, 510, 511 and 512
