The 493 is a single-channel relay unit, designed to allow interfacing with other building control and management systems.
The 493 signal relay unit is in a plastic enclosure, so it can be installed within a third-party equipment enclosure, electrical cabinet, or used as an in line unit.
The relay is a solid-state, normally open signal relay, with a contact rating of 60 VAC or VDC, at a maximum of 0.5 A.
This unit must not be used to switch mains voltages.
The unit is powered from the DALI network.
The compact enclosure has mounting lugs at each end, and cable grips are provided as part of the terminal cover.
The unit forms a DALI relay node with a typical current consumption of 10 mA, and is programmable as a single-channel relay by Helvar’s lighting design software, Designer and Toolbox.
Note: This unit does not contain a DALI power supply and therefore one must be incorporated elsewhere in the system.
