Spec 1603

Model SEQ-8 Rev. 08-12-21 | pg. 1/4

INTERNAL USE ONLY: PN 24369

Compact low voltage eight step sequencer model SEQ-8 is

designed to work with single or multiple external switches and

low voltage remote power controls (RPCs) to provide time-

delayed activation and deactivation of AC powered equipment

on site or at remote locations.

Note: This sequencer is for use with compatible components that feature classic

connections. It is not for use with devices that feature pass-through connections.

FEATURES:

• Power Requirement: 100-240VAC 12W

• Activation Trigger: Sequencing is initiated by a remote

external SPST switch or switches (order separately). Slide the

bar to select single or multiple switch mode.

– For Single Switch Applications: Use an SPST switch with

MAINTAINED contact closure.

– For Multiple Switch Applications: Use SPST switches with

MOMENTARY contact closure.

• Eight (8) Step Delay:

– Eight time-delayed closure circuits activate in sequential

order (1, 2, 3, 4, 5, 6, 7, 8) and deactivate in reverse order.

– The delay between steps can be adjusted via an externally

accessible trimpot (0.5-10 seconds).

– LEDs provide visual status of the sequence.

– Includes auxiliary 24VDC output (300mA max.) for use with

remote indicators.

• Compact Chassis: 10" x 3.28" x 1.69" steel chassis with

black powder epoxy finish and mounting holes.

– Unit can be installed in a remote location or rack panel (2U).

– Operational diagram printed on top of chassis aids system

set-up.

• Country of Origin: Made in U.S.A. with global components

• Power Supply: UL Listed power supply (100-240VAC input,

24VDC 500mA output) with 6 ft. cord and NEMA 1-15P plug.

Includes three adaptors for international use (Schuko CEE

7/16, BS1362, AS3112).

• Installation: The sequencer is typically installed in a

convenient location, while remote power controls are placed

near equipment to be controlled—in another rack, room or

building.

– Maximum distance between sequencer and remote power

controls: 22 gauge wire = 6,600 ft.; 18 gauge wire =

17,160 ft.

– Maximum distance between sequencer and switch:

22 gauge wire = 100 ft.; 18 gauge wire = 200 ft.

– System Capacity: Accepts up to 10 RPCs per step.

• Connections: Order compatible remote power controls and

switches separately. (See last page.)

• A&E Specications: The power sequencer shall be Lowell

model SEQ-8, which shall feature barrier strip terminals for

connection to a single external SPST switch with maintained

contact closure or multiple external SPST switches with

momentary closure. The sequencer shall connect to remote

power controls (RPCs) to activate equipment in up to eight

steps with an adjustable time delay between each step. It shall

activate the RPCs in sequential order and deactivate them in

reverse order. The sequencer shall feature a steel chassis

with mounting holes, black powder epoxy finish, and overall

dimensions of 10" x 3.28" x 1.69". shall be made in the It

USA with global components, and include a UL Listed power

supply with NEMA 1-15P plug and three adaptors (Schuko

CEE 7/16, BS1362, AS3112). External switch(es) and remote

power controls are required for sequencer use and shall be

ordered separately.

INTERNAL USE ONLY: PN 24369

Connect one Lowell RPS Series switch that features MAINTAINED closure

(remains on until turned off). The switch will feature one LED and use

three conductors.

Set sequencer to Single Switch. Connect equipment to Lowell RPC Series

remote power controls that feature classic connections (not pass-through),

and connect the RPC (switch and common terminals) to one of the steps

on the sequencer. Up to 10 RPCs can be connected in parallel on each

of the eight circuits.

Max. distance between SEQ-8 and RPCs: 22-gauge wire = 6,600 ft.; 18-gauge wire = 17,160 ft.
