RDM-3SWM

 Triple Switch Module 20A

The RDM-3SWM Triple Switch Module is a 20 A triple general purpose 
relay module built for compact and economical switching of incandescent 
lamps, switched low-voltage transformers, switched fans and electrical 
outlets. It is designed for use with the RDA series of enclosures, in an AMX 
Lighting™ modular digital dimming system. The RDM-3SWM uses positive 
air gap type relays. This module's 120, 240, and 277 VAC ratings are CE, 
UL, and C-UL approved.
