RDM-2SWM Dual Switch Module 20A
The RDM-2SWM Dual Switch Module is a 20 A general-purpose relay
module built for the economical switching of incandescent lamps, switched
low-voltage transformers, switched fans, and small motors. It uses positive
air gap relays. The RDM-2SWM is designed for use with the RDA series of
enclosures, in an AMX Lighting™ modular digital dimming system. This
module's 120, 240, and 277 VAC ratings are CE, UL, and C-UL approved.
