Spec 2216

Model SEQ-4A Rev. 09-20-22 | pg. 1/3

INTERNAL USE ONLY: PN 24188

Compact low voltage four step sequencer model SEQ-4A is

designed to work with a single external switch or voltage input

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: This sequencer requires an external

source for activation. See last page for compatible

components.

– Single remote SPST switch with contact closure.maintained

– Mulltiple remote SPST switches with contact momentary

closure and Lowell's MSM2 module connected between

the sequencer and switch.

– Voltage input (5V-24V, AC or DC)

• Four (4) Step Delay:

– Time-delayed closure circuits activate in sequential order

(1, 2, 3, 4) and deactivate in reverse order.

– The delay between steps can be adjusted by setting the DIP

switch on the front (2.5 to 12 seconds between steps). A

reference chart is printed on the top of the chassis.

– LEDs provide visual status of the activation sequence.

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

remote indicators, if needed.

• Compact Chassis: 8.00" x 3.25" x 1.95" (4 lbs.) 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 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 switch, sequencer and remote

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

= 17,160 ft.

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

• Connections: Order compatible remote power controls and

switches separately.

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

model SEQ-4A, which shall feature barrier strip terminals for

connection to a single external remote switch with maintained

contact closure, multiple remote switches with momentary

closure and Lowell MSM2 module wired between them, or a

voltage input trigger. The sequencer shall connect to external

remote power controls (RPCs) to activate remote equipment in

four steps with an adjustable time delay between each step.

It shall activate RPCs in order (1, 2, 3, 4) and deactivate them

in reverse order. The sequencer shall feature a steel chassis

with mounting holes, black powder epoxy finish, and overall

dimensions of 8.00" x 3.25" x 1.95". shall be made in the It

USA with global components, and include a UL Listed power

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

CEE 7/16, BS1362, AS3112). External switches and remote

power controls shall be ordered separately.
