The RD121 is a 14,400 Watt, 12 channel, rack mount lighting dimmer. It is suitable for church, stage, theater, school, night club, live performances and other event and artistic applications. Each of the channels has a capacity of 1200 Watts. It is controlled via low voltage signals which may be LMX-128 (3 wire multiplex), or USITT DMX- 512. The unit is fan cooled. Channels may be independently assigned from the unit. The unit is over temperature and over voltage protected and has a magnetic circuit breaker for each channel. There are several options for channel output connection panels. Options include: Edison plug, Knockout panel with internal terminal strip, External Terminal Strip, Patch panel, Stage pin panel, and Socapex Connector panel. The RD121 also has several "stand alone functions" which enable it to operate without a control console. These functions |

Architect & Engineer’s Specifications
The dimming system shall have 12 circuits with a load capacity of 1200 Watts per circuit. Each circuit is protected by a 10 Amp fast acting magnetic circuit breaker. An allowance of 200% overhead capacity is employed in the circuit design. The dimming system shall have a rise time of not less than 350 microseconds. Programming setup and memory attributes is via a front panel LCD display with keypad controls. A user may program the system setup, dimmer attributes of Dim or Relay, Softpatch, a single scene memory and a chase via the front panel display and keypad controls. There are seven preset chases and one user programmable chase, a maximum of 32 steps are available in the chase, chase steps are programmable in 1/4 Sec. increments, 1/4 sec to 16 1/2 Minutes in length. The single scene and chase on/off are recalled via contact closure. The dimming system uses the USITT standard DMX-512 protocol and LMX-128 protocol for direct control of the dimming circuits. Power requirements of the dimming system shall be 2 hots of 120VAC Single/Three phase service. Capacity shall be 60 Amps per leg. DMX-512 and contact closure are connected through a standard DB9 connector, a ribbon connector is used to pass data to subsequent RD series dimmers. A variety of electrical output connections are available including Stage Pin, Socapex, Patch Bay (Powerlock), Duplex (Edison) and External Terminal Strip. Mounting of the dimming system shall be on standard 19” EIA rack mount. All components and sub-systems of the dimming system shall be UL recognized and conform to the standards set forth. Dimensions are 3.5”H x 19”W x 13”D and the weight shall be 27 lbs.
