ILC Lighting Relays 2R7CDD, 2R9CDD

ILC Lighting Relays


ILC Model 2R7CDD and 2R9CDD lighting Relays are mechanical latching-type units requiring only a momentary 24 VDC or VDC switch circuit pulses to open or close line voltage circuits. All ILC low voltage relays may be used to full rated capacity for ballast or resistive loads. The Model 2R9CDD includes an auxillary contact on the low voltage side for status indication.
