Introduction The 458/SW8 is a 8-channel switching module. It uses high inrush relays to withstand short-lived high peak current inrush when switching on loads. It has both a DALI and an S-DIM/DMX interface, and therefore can be fully integrated into a Digidim or an Imagine router system.
Attach the module to a chassis Mounting, Environmental and Clearance Requirements Mounting • Attach the 458/SW8 to a 458M1, 458M2, or 458M3 chassis, which is mounted vertically on a flat surface. Environment • The ambient temperature must be between 0ºC and 40ºC.

S-DIM or DMX connector. Switch closure sets the light level of all output channels to the override level. S-DIM and DMX connections If connecting to a Helvar Imagine system, plug in the connector of the S-DIM/DMX cable loom to the S-DIM/DMX terminals. This is attached to the DIN-rail inside the chassis.
