IMPORTANT SAFETY INSTRUCTIONS

Your UNIVERSAL INPUT MODULE has been carefully designed to give you years of safe,
reliable performance. As with all electrical equipment, however, there are a few basic precautions
you should take to avoid hurting yourself or damaging the unit:

•Read the installation and operating instructions in this manual carefully. Be sure to
save it for future reference.

•Read and follow all warning and instruction labels on the product itself.

•To protect the Universal Input Module from overheating, make sure all openings on
the unit are not blocked. Do not place on or near a heat source, such as a radiator or
heat register.

•Do not use your Universal Input Module near water, or spill liquid of any kind into
it.

•Be certain that your power source matches the rating listed in the specification
section of this manual. If you’re not sure of the type of power supply to your facility,
consult your dealer or local power company.

•Do not allow anything to rest on the power cord. Do not locate this product where
the cord will be abused by persons walking on it.

•Do not overload wall outlets and extension cords, as this can result in the risk of fire
or electric shock.

•Never push objects of any kind into this product through ventilation holes as they
may touch dangerous voltage points or short out parts that could result in a risk of
fire or electric shock.

•To reduce the risk of electric shock, do not disassemble this product, but return it to
Phonetics’ Customer Service, or another approved repair facility, when any service or
repair work is required. Opening or removing covers may expose you to dangerous
voltages or other risks. Incorrect reassembly can cause electric shock when the unit is
subsequently used.

•If anything happens that indicates that your Universal Input Module is not working
properly or has been damaged, disconnect it immediately and follow the procedures
in the manual for having it serviced. Return the unit for servicing under the follow­ing conditions:

1. Liquid has been spilled into the product or it has been exposed to water.

2. The unit has been dropped, or the enclosure is damaged.

3. The unit doesn’t function normally when you’re following the operating
instructions.

FCC Requirements

Part 15: This equipment has been tested and found to comply with the limits for a Class A
digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when the equipment is operated in a com­mercial environment. This 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. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at his
own expense.

Introduction

The SCADA 3000 Universal Input Module is an optional component for use with the SCADA
3000 system. The input channels are identical to those included on the SCADA 3000 main unit.
The Universal Input Module features eight channels that can be configured to interface with
several different types of sensors and transducers, including: Normally Open/Normally Closed
dry contacts, digital logic, Run time Accumulation, 0-5V analog, 4-20mA analog and 10K
thermistor (ºC & ºF). The module features 12-bit resolution, differential inputs, 24V supply for
powering 4-20mA loops and low-power operation. Each input is protected by a 1500 Watt
transient suppressor. In addition, a microprocessor watchdog circuit is integrated to maintain
system reliability. LED indicators are provided to show system power and module operation via
a blinking pulse LED.

I. Installation

This chapter provides information necessary to install the Universal Input Module. Correctly
installing the unit will ensure proper functioning and maximum service life. Please read the
entire chapter before attempting installation.

OPERATING ENVIRONMENT

The Universal Input Module should be mounted and operated in a clean, dry and safe environ­ment. Do not mount the unit where it will be subject to shock and vibration. Do not mount
the unit where it will be subject to dirt, dust or moisture. Ideally the unit would be mounted in a
steel or a fiberglass NEMA-4 enclosure. Do not mount the unit or the expansion modules close
to motor starters, contactors or relays that switch inductive loads. These devices generate large
electromagnetic fields that can cause the Universal Input Module to malfunction. Where this is
unavoidable, mount the module(s) and main unit in a separate, grounded, steel enclosure. This
will shield them from harmful electrical interference.

The temperature range the Universal Input Module can operate in is 32°F to 158°F (0°C to
70°C). If you require Universal Input Module to operate in a below freezing environment, you
must take safe and practical measures to keep the module’s temperature above 32°F or it will not
operate reliably.

CAUTION: The Universal Input Module is a sensitive electronic device. Person­nel and work area should be grounded before handling this device. Do not install a
SCADA 3000 system near any strong electrostatic, electromagnetic, magnetic or
radioactive fields. Do not expose it to fumes or corrosive vapors.

MOUNTING THE UNIVERSAL INPUT MODULE

When you receive the Universal Input Module, carefully remove it from the box. On the top
and bottom of the enclosure are mounting holes to attach the unit to either a panel or wall. The
mounting surface should be sturdy enough to support 2 lbs. The unit should be mounted using
four #10-32 bolts where appropriate, or four #10 tapping screws. (The screw kit for the Uni­versal Input Module includes 4 #10-32 screws, 4 #10-32 nuts, 4 #10 lockwashers, and 2 #6-32
screws, 2 #6-32 nuts, and 2 #6 lockwashers. The #6 hardware is for the power supply, if neces­sary.) When mounting the unit to a wall make sure the mounting screws fully engage a solid
member (for example, a stud) of the support structure. Mount the Universal Input Module in an
upright position so that you can easily connect wires to the terminal strips. The dimensions of
the full enclosure are: 6.1" x 6.3" x 1.2". See Figure 1.
