The 458/DIM4 is a four-channel thyristor dimmer module, for leading-edge dimming of resistive and inductive loads. The module has 4 channels rated at 10 A each, with a total current capacity of 40 A.

The module has DALI, DMX, and S-DIM interfaces for integration into DIGIDIM and Imagine systems. The optional 458/OPT4 module allows 4 dimmed channels to be converted to 4 ballast control channels.

It can be fully integrated into a Digidim or an Imagine router system. It can also be used on the TouchPanel, or used on standalone DALI or Digidim systems.
