INTERNAL USE
ONL
Y:
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 maintained contact closure.
– Mulltiple remote SPST switches with momentary contact
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 Specifications:
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". It shall be made in the
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.
