Product Description


SEQ-4: Power Sequencer (4-step)


Four-step power sequencer is used with low voltage remote power controls and switches to provide time-delayed activation and deactivation of AC powered equipment on site or in a remote location.



  • Compact Chassis: 7.00 in. x 3.281 in. x 1.687 in.
  • Four delayed closure circuits activate in sequential order (1, 2, 3, 4) and deactivate in reverse order (4, 3, 2,1). Sequencing is initiated by an external remote switch (order separately). Solid state circuitry operates using a single remotely located SPST maintained contact closure switch (order separately)
  • LED status indicators
  • Adjustable delay allows 0.5 to 10 seconds between steps.
  • Auxiliary 24VDC, 300mA (max) output for remote indicators
  • UL Listed power supply with input 100-240VAC, output 24VDC, 500mA, 6 ft. cord and four plug adaptors (NEMA 1-15, Schuko CEE 7/16, BS1362, AS3112)


  • Made in U.S.A. with global components


  • The device for sequentially activating equipment connected to remote power controls shall be Lowell Model No. SEQ-4, which shall feature barrier strip terminals for connection to remote power control Model No. RPC- ________. Contacts shall also be available for connecting remote switches (required) for activation. [ Applications with multiple switch actuation shall use momentary wall switch Model No. _____ or momentary rack panel switch Model No. ______. Applications with single switch actuation shall use maintained wall switch Model No. ___ or maintained rack panel switch Model No. _____. ]
