The 458/SW8 is an eight-channel A channel pertaining to a load (also known as control gear or LIU), see entry for load. A ballast has one channel, whereas a dimmer or relay unit can have numerous channels. switching module. The module contains eight relay channels (normally open) capable of switching 10 A per channel.

It uses high inrush relays to withstand short-lived high peak current inrush when switching on loads. It has both a DALI Stands for Digital Addressable Lighting Interface. Standardised digital protocol for lighting control, allowing communication between control devices and LIUs (control gear). and an SDIM Stands for ‘Serial DIMming communication’. It is a Helvar communication protocol. interface, therefore it can be fully integrated into a DIGIDIM or an Imagine router In the sense of a lighting system, a router is an intelligent device whose software and hardware perform the tasks of routing and forwarding messages (data) from control devices to the control gear. A router contains two or more subnets. system.

The front of the module is equipped with an LCD display with intuitive cursor control, to set some basic configuration parameters and provide basic manual control.
