|
The DIGIDIM 498 is an eight-channel relay unit fitted with high inrush specification relays. This means that the short-lived, high-peak current inrush caused when switching on loads, such as electronic ballasts, is handled by a set of premake contacts that close before the main contacts of the relay. This allows more high inrush loads to be switched from one relay, where the limiting factor with standard relays was inrush current.
