RDL®

HD Series products are constructed in durable metal enclosures ½ rack width, 2RU in height. This series features front-panel user controls and indicators. Connectors are located on the rear panel. Chassis are finished in black powder coat. The front panels feature a full color reverse-printed polycarbonate laminate surrounded by raised end caps. The distinctive appearance of the HD products complements rack mounting or standalone use.

The front panels feature bold graphics, simple indicators and large comfortable control knobs and buttons for ease of use by end users. HD products offer a broad range of features and external controls and module accessory connections on the rear panels.

Available RDL accessories permit one or two HD products to be mounted in 2 RU. Rack mounting is easy and takes only seconds. The HD product drops into the rack adapter, slides forward and is secured by tightening four screws. For standalone use, each product is supplied with rubber feet secured by screws. HD accessories permit a variety of mounting options to conceal wiring for a professional finished appearance.

Attractive styling, intuitive end-user operation, high quality panel controls and connectors, and durable construction make RDL HD products a preferred long-term resource for system design solutions.
