8x20 A Relay Controller (499) Relay unit with manual override Designed for installations that use a lot of power, such as high-bay luminaires and do not require dimming capabilities. Most beneficial for large space applications with high power lighting loads, such as warehouses, the additional monitoring and control capabilities offered with the 499 can significantly improve ease of use with manual switching. Especially beneficial in the event of a fault or where local tasks need to be carried out, such as lamp maintenance. You are able to see the position of the relays at any moment, turn on and off the lights for testing purposes, or switch the loads on and off even if the unit loses control. In addition, if power is disconnected to the unit, the latching relays stay in the same position. • • • • • • Pictures © Malmöbild/Drago Prvulovic - NIBE, Skane Warehouses Arenas Industrial Supermarkets Airports Retail 8x20 A Relay Controller (499) E&OE V2.200116-499 Technical Data Connections Mechanical data Mains/relay: Up to 4 mm2 solid core or up to 2.5mm2 stranded DALI: 0.5 mm2 - 1.5 mm2 stranded or solid core Max. length: 300 m @ 1.5 mm2 SDIM/DMX: Cable rating: 0.22 mm2 - 1.5 mm2 / low-loss RS485 type multistranded, twisted and shielded All cables must be mains rated.
