The MINIPORT-20 Power Relay is a UL/CUL listed, 20 amp, relay switched 120 VAC outlet, with a terminal strip that allows remote control via safe, inexpensive, low voltage Class 2 wiring. Also available is the MINIPORT-15, which is functionally identical except for its 15 amp rating. Both models include an internal 12 VDC supply, and can be controlled from a remote location with maintained or momentary contact switches.

Multiple MINIPORTs may be connected together so that all are controlled by a single switch closure, and may be linked so that all turn on simultaneously or one by one, in a delayed sequence. If delayed, the delay interval between the turn-on of one MINIPORT and the next is approximately 3 seconds. (Delayed turn-on is useful in avoiding large inrush currents that can trip house circuit breakers, that would otherwise occur if all amps were turned on simultaneously.) Turn-off always occurs simultaneously, however.
