The DMX1REL20A-2POLE controls two output legs using a single channel of DMX512. The relays can switch up to a 20 amp line voltage load and are built with a 30 amp relay for robust performance. The output is suitable for 208-240VAC with both the hot legs being switched. The unit is provided with two 18" 12/3 SJ pigtails for line in and switched line out. Supplied with 20 amp twist lock connectors (L6-20) as standard, the unit may be wired with different connectors by special order or may be rewired by the customer. The DMX1REL20A-2POLE also includes another 30 amp relay so that both the "hot" legs are switched. This unit is supplied with 20 amp twist lock connectors (L6-20) and also operates on 208-240V 50/60Hz.
Doug Fleenor Design Relay Packs use dry contact air-gap relays. These relays have advantages and disadvantages over the solid state relays found in dimmer packs. Solid state relays can be switched on and off rapidly with no wear, but tend to leak current even when in the off position. Air-gap relays do not leak current, but due to their mechanical design have a finite life span. Doug Fleenor Design Relay Packs should be used where a true off condition is required (no voltage, no current). They should not be used in applications where they will be turned on and off rapidly (for example in chase lights). Ideal applications include fog machines, power to moving light fixtures, motorized disco effects, strobe lights, fans, operating at 208VAC or 240VAC.
