You Need The RU-SQ6A!

The RU-SQ6A is part of the group of versatile RACK-UP products from Radio Design Labs. RACK-UPs feature the
advanced circuitry for which RDL products are known, combined with accessible, user-friendly controls and displays.
The ultra-compact design permits high-density installations, with three products mounted in a single rack unit! Single
RACK-UPs can be mounted right where they are needed using the adhesive methods popularized by RDL’s
STICK-ON
any flat surface. Optional rack-mount adapters and chassis are available for conventional RACK-UP series
installation.

APPLICATION: The RU-SQ6A is the ideal choice in installations where sequential ON and sequential OFF
functions are desired. Control and output connections are made on the rear panel through clearly identified
detachable terminal blocks.

Two types of outputs are provided for each of the 6 sequential steps. One type is an open collector capable of
switching loads of 50mA. The other type is an SPST dry contact closure which may be used to control a variety of
equipment. A single-turn front-panel TIMING INTERVAL control adjusts the time delay between channels from 1 to
10 seconds. Front-panel LEDs show when each output channel turns on and off. An internal microcontroller insures
reliable, accurate timing.

The up or down sequence is user-controlled by a front-panel pushbutton switch unless the module is set for remote
operation. A rear-panel switch set by the installer selects either front-panel or remote control activation. LEDs
indicate whether the front-panel SEQUENCE CONTROL switch or the remote terminals are active. Grounding the
rear-panel ACTIVATE terminals or turning on the front-panel SEQUENCE CONTROL switch causes an UP

REQUEST that starts the RU-SQ6A outputs to turn on sequentially. The outputs remain active until the UP
REQUEST is cancelled by turning off the front-panel or remote control switch, causing the outputs to turn off in

reverse sequence. If the ACTIVATE terminal is permanently grounded with the module set for remote control, the
RU-SQ6A outputs will turn on sequentially when power is applied to the module; all outputs will turn off
simultaneously when power is removed from the RU-SQ6A. The UP REQUEST LED is illuminated when an UP
sequence is requested. When the sequence is complete, the COMPLETE LED indicates the
supervisory circuit is actively latching the outputs active until the user deactivates the sequence.

Wherever sequential up and down switching is needed the RU-SQ6A is the ideal choice. Use the RU-SQ6A
individually,
system.

NOTE: This equipment has been tested and found to
comply with the limits for a Class B digital device, pursuant
to part 15 of the FCC Rule. These limits ar e designed to
provide reasonable protection against harmful interfer enc e
in a residential installation. The equipment generates,
uses and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions,
may cause harmful interference to radio communications .
However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does
cause harmful interference to radio or televis ion reception,
which can be determined by turning the equipment off an
on, the user is encouraged to try to correct the
interference by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the equipment

and receiver

• Connect the equipment into an outlet on a circuit
different form that which the receiver is
connected.

• Consult the dealer or an experienced radio/TV
technician for help.
