RDL AV INTERFACES - RACK-UP Series

RDL Rack-Up series are 1/3 rack-width, rack-mounting modules, 1U high, offered with a wide range of functionality. Some Rack-Up modules are constructed in solid, encapsulated, durable, industrial, black plastic enclosures; Max Rack-Ups are assembled using heavy-duty, extruded-aluminium and steel panels. The rear panels have 'clear bold white lettering' for the terminal blocks and connectors. Reverse-printed, front-panel, poly-carbonate laminates provide a durable finished appearance for rack-mounted or free-standing use. Certain Rack-Up modules are often used free-standing; all Rack-Ups may be rack mounted by means of a range of mounting options, listed within this group.

Powering

Powering: All units require a 24V DC power supply; each has both screw terminals and coaxial socket for power input. A ‘universal’ supply is available, 57-401, with 24V 3A output, which requires an IEC cord set. See RDL POWER SUPPLIES for more details. Note that all RDL modules with co-axial power input/output sockets use connectors with 2.5mm pins.
