1.2 Manual
Conventions To help you get the most out of this manual and our products, please note that
we use the following conventions:
Tips are designed to highlight quick ways to get the job done, or reveal
good ideas you might not discover on your own.
NOTE: Notes alert you to important information.
CAUTION! Caution advises you of precautions to take to avoid injury, data loss,
and damage to your boards or a system crash.
Text formatted in bold typeface generally represents text that should be entered
verbatim. For instance, it can represent a command, as in the following
example: “You can instruct users how to run setup using a command such as
setup.exe.”
Bold typeface will also represent field or button names, as in “Click Scan
Network.”
Text formatted in fixed typeface generally represents source code or other text
that should be entered verbatim into the source code, initialization, or other file.
Before you begin:

Before plugging any I/O connector into the Cube or RACKtangle, be
sure to remove power from all field wiring. Failure to do so may
cause severe damage to the equipment.
No HOT SWAP
Always turn POWER OFF before performing maintenance on a UEI system.
Failure to observe this warning may result in damage to the equipment and
possible injury to personnel.
Usage of Terms
Throughout this manual, the term “Cube” refers to either a PowerDNA Cube
product or to a PowerDNR RACKtanglerack mounted system, whichever is
applicable. The term DNR is a specific reference to the RACKtangle, DNAto the
PowerDNA I/O Cube, and DNx to refer to both.

1.3 The DIO-470
Board The DNx-DIO-470 is a 10-channel electromechanical relay output board
designed for driving solenoids, motors, or other inductive loads. The 10
independent digital outputs on the DIO-470 are configurable to provide output
control and switching (up to 750 VA) for 10 channels (total).
DNA-DIO-470, DNR-DIO-470, and DNF-DIO-470 boards are compatible with
the UEI Cube, RACKtangle, and FLATRACK chassis respectively. These board
versions are electronically identical and differ only in mounting hardware. The
DNA version is designed to stack in a Cube chassis. The DNR/F versions are
designed to plug into the backplane of a RACK chassis.
NOTE: Refer to Section 1.8 for additional information about DNAversion height
requirements.
1.4 Features The main features of the DIO-470 are listed below:
•10 Form C electromechanical relay outputs (total)
•5 A @ 30 VDC or 0.4 A @125 VAC continuous per channel maximum
current rating
•Ideal for driving solenoids, motors, or other inductive loads
•Output throughput rate 125 updates per second max
•Guaranteed output OFF state on initial power-up, external power OFF,
internal power OFF, and overload detected
•Isolation of 350 VDC between channels, and other components
•Output OFF leakage <100 uA
