1 PRODUCT OVERVIEW
1.1 GENERAL DESCRIPTION
The Ultra Series Integrated Signal Conditioning (ISC) Cantilever tension transducer (see Figure 1) outputs
a +/- 10 VDC signal for reporting signals from strain gage-based load cells. Ultra ISC transducers include
an Integrated Signal Conditioner (ISC) that is coupled directly to the “Ultra” type load cell employing
semiconductor strain gages. This local processing reduces the signal degradation due to long wires to the
driving displays or recording devices. Note: Customer must supply Roll shaft and bearings.
Because the output stage is free to float, voltage differences on the output side of th e
tension transducer with respect to protective earth ground.
Figure 1 Ultra Series Integrated Signal Conditioning (ISC) Cantilever Transducer
The Integrated Signal Conditioning (ISC) amplifier has a separate ground reference (common) for the output
signals. The ground used by the output circuits is electrically separate from the ground return for the fixed
24Vdc supply. The 24Vdc supply input is protected against reverse polarity.
The Integrated Signal Conditioning (ISC) Amplifier uses an embedded Instrumentation Amplifier (IA) to
amplify the millivolt level signals generated by the strain gage bridge, while effectively rejecting commonmode noise. Low drift Surface Mount Technology (SMT) components, Multi-layer Printed Circuit Boards
(PCB) and optimum circuit topologies are incorporated to promote load cell signal integrity.
The Amplifier gain is adjustable over a 9.6:1 range to allow span calibration of the analog outputs.
A precision low voltage excitation source is provided for exciting the strain gage elements in the internal
strain-gage bridge.
The use of galvanic isolation can aid in reducing noise pickup caused by ground loops in the field wiring and
accommodates only limited voltage gradients between input and output sections of the application wiring.

1.2 FEATURES
Ultra ISC load cell features are:
Factory Calibration promotes interchangeability
Tension controller observation of individual load cell signals provides increased opportunity for
advanced diagnostics and calibration.
Self contained precision excitation circuit eliminates the need for the expense and complication of
remote sense
24V supply has reverse polarity protection
Analog output buffer designed to accommodate capacitive cable loads.
Floating strain-gage and output stage allows “stacking” ISC outputs for simple summing.
Sealed enclosure and M12 connector provide environmental protection
Industry standard M12 allows use of readily available molded cordsets
1.3 HOW IS THE ULTRA ISC USED
The Ultra ISC load cell has been developed for those customers who desire to send the amplified transducer
signal directly into their Controller, PLC, PAC, Drive, or Local I/O.
The Ultra ISC load cell is shipped preset from CMC with 0 volts representing no load, and 10 volts
representing the 100% full rating of the transducer. (Example: A 100 lb Ultra ISC transducer with no load
outputs 0 volts. With a 100 lb. load the output is 10 VDC when loaded in one direction and -10VDC when
loaded in the opposite direction.)
1.4 CE EMC RESPONSIBILITY
The Integrated Signal Conditioning (ISC) Amplifier Ultra Series ISC module embedded in the load cell can
be considered a component performing a direct function and therefore is subject to the provisions of the
EMC Directive.
To assist manufacturers, suppliers, and installers of relevant apparatus, this amplifier module is compliant
to EN61326:1997 when installed according to these instructions. Manufacturers, suppliers, and installers
of relevant apparatus may use this compliance as a contributing basis for their own justification of overall
compliance with the EMC Directive.
Before installing the Ultra Series ISC Amplifier you must clearly understand who is legally responsible for
conformance with the EMC Directive. Misappropriation of the CE mark is a criminal offense.
