Product Description


SEQR-P4: Rackmount Sequencer w/pass-through jacks

This low voltage rackmount power sequencer with pass-through RJ45 jacks for quick connections works with compatible remote power controls (RPC-P Series) and relays (RY-P Series) to provide time-delayed activation and deactivation of AC powered equipment at remote locations.


  • Quick "pass-through" connections with two RJ45 jacks
  • Because the step assignment is actually selected on the connected devices (RPC-P Series remote power controls or RY-P Series relays), the startup sequence can be quickly changed without the need to re-wire.
  • Four delayed closure circuits activate in sequential order (1, 2, 3, 4) and deactivate in reverse order (4, 3, 2,1). Delay between steps is easily adjusted with DIP switch.
  • Sequencing is initiated via rocker switch on front panel. Remote switches can also be added (see spec sheet).
  • 19" x 9" x 1U chassis
  • LED status indicators
  • UL Listed power supply with input 100-240VAC, output 24VDC, 500mA, 6 ft. cable with several plug adaptors.


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


  • The power sequencer shall be Lowell model SEQR-P4, which shall feature a 19" x 9" x 1.75" (1U) steel rackmount chassis with black powder epoxy finish and a UL Listed power supply with 100-240VAC input, 24VDC 500mA output and 6 ft. cable. The sequencer shall feature four delayed closure circuits in two RJ45 output jacks to activate and deactivate connected devices in a predetermined order, providing adjustable time delays between steps. Activation shall be via a rocker switch on the front panel, however, the unit shall accept remote activation via an external trigger such as an SPST momentary switch, DSP connection, or system switch with dry contact closure. The unit shall include an alarm interface for use where required by building code. All remote triggers shall be ordered separately or provided by others. The sequencer shall only work with compatible remote power controls and relays that feature pass-through RJ45 jacks (Lowell RPC-P Series and RY-P Series only), which shall be ordered separately.
