1. INTRODUCTION
The ABUS USI Series Universal Smart Isolator being programmable through
Handheld Configurator USI-C can be fit into major of industrial applications operating
with different signals. It can be ordered to accept up to 2 inputs and provide up to 3
outputs. The input signals can be non-linear input such as resistance temperature
detector, thermocouple or linear current or voltage. Signal of one-way, two-way or
three-way current or voltage, isolated by transmitting output provides good electric
isolation between input, output and power. It can be used as a temperature
transmitter, convertor, signal isolator or signal conditioner according to the application.
2. PRESENTATION
2.1 Features
This product uses a special chip. It has many advanced performances which traditional
USI
analogue isolator and many digital isolators don’t possess. This chip provides restrict and process from
software to high/ low-frequency interference signal in input signals. Even in high-power frequency
conversion system it can keep reliable performance. With the help of strong function of this chip
instrument can carry on digitalized automatic/ manual regulation to signal without the help of outside
zero and full-scale potentiometer. Meanwhile it can go on automatic compensation to input signals.
This series of products can also use integrated communication protocol, with the help of the
connection of communicational methods, observing input and output values on line. The integrated
smart isolator using a special chip, besides universal functions, can support the logical process to signal
and set alarm output to condition.
Unique and strong functions of software of the chip and excellent electric performance of
hardware of isolator itself provide firm assurance for stability and reliability of products. And it makes
overall performances of products lead of international advanced standard.
Series of instruments can be used with unit group instruments and DCS, PLC, etc. They are
widely used in all kinds of industries such as oil, chemical, petro-chemical, power, food, steel,
pharmaceutical industries etc...

5. CONNECTIONS
USI
1. For thermocouple input, use the specified comenssation wire.
2. For RTD input, use leads with low resistance and having no resistance differences among the 3
leads.
3. Conduct input signal wiring away from instrument power, electric equipment power and loads lines
to avoid noise induction.
4. Conduct instrument power wiring so as not to be influenced by noise from the electric equipment
power. If the instrument is affected by external noise, a noise filter should be used.
a. Shorten the distance between twisted power supply wire pitches. The shorter the distance
between the pitches, more effective is the noise reduction.
b. Install the noise filter on the panel which is always grounded and minimize the wiring distance
between the noise filter output side and the instrument power terminals.
c. Do not install fuses and/or switches on the filter output signal since this may looses filter effect.
5. For wiring, use wires conforming to the domestic standards of the countries.
6. This instruments has no power supply switch for fuses. Therefore, install the fuse close to the
instrument and theswitch, if required.
7. Do not excessively tighten the terminal screws. In addition, use the solderless terminal with respect
to the screw size.
6. INSTALLATION
Recommendation
1. This instrument is intended to be used under the following OVERVOLTAGE CATEGORY II, and
POLLUTION DEGREE 2,
2. Use this instrument within the following ambient temperature and humidity.
a. Temperature: 0~50°C
b. Humidity: 45~85% RH
3. Avoid the following when selecting the mounting location:
a. Rapid changes in ambient temperature which may cause condensation.
b. Corrosive or inflammable gases.
c. Direct vibration or shock to the mainframe,
d. Water, oil, chemicals, vapor or steam splashes.
e. Excessive induction noise, static electricity, magnectic fields or noise
f. Exposure to direct sunlight,
g. Excessive heat accumulation.

9. MAINTENANCE
9.1 Calibration of Instruments
The operation can be realized through ABUS-1001 Operator. The set parameters use the same
USI
calibration way as that of 585 and support automatic calibration.
9.2 Operation Environment
At mounting position strong vibration or strong electromagnetic impact from signal terminal,
power terminal, power terminal and room is not allowed. In operation environment, poisonous or harmful
matters which will corrode metals and plastics are not allowed to exist. Please keep the operation
environment dry for the precise output.
9.3 Troubleshooting
There are two kinds of trouble in input signals: input trouble (open circuit, short circuit) and
beyond span trouble.
Output ways at input trouble: Instruments can select beyond-span gain output and general output.
Gain Output
At the condition of beyond upper limit, output signal has a gain exceeding 5% of normal output
value;
At the condition of beyond lower limit, output signal has an output lower than 5% of lower limit; if
lower limit is zero (i.e.0 ~ 5 V) then output is 0 V.
General Output
At the condition of beyond upper limit, output maximum value or setting value;
At the condition of beyond lower limit, output minimum value or setting value;
At the condition of trouble, keep output value or setting value before output trouble;
Under trouble of input signal, trouble light of instrument flickers to indicate signal trouble.

10. SAFETY PRECAUTIONS
1. The unit should be powered for 15 minutes before use.
2. Use in ambient temperature of 0-60˚C.
3. Avoid vibrations, shock, excessive dust, corrosive chemical materials or gaseous
environment.
4. Input wire should not be too long. If measured signal have to be far away from the
unit, please use 2-core shielded cable.
5. Use this instrument in the scope of its specifications, otherwise fire or malfunctions
may result.
6. Contact of the instrument, with organic solvents or oils should be avoided.
