low-cost, versatile method of transferring analog transducer
signals to a data acquisition, monitoring or control system
without the inherent noise, non-linearity, drift and extraneous
voltages. The modules are designed to directly accept analog
signals from Thermocouples, RTD's, AC and DC Strain Gages,
Torque Transducers, Frequency Transducers, LVDTs, millivolt
or process current signals. The modules amplify, isolate,
linearize and convert the transducer output signals to
standardized analog inputs for high-level analog I/O
subsystems. The 3B Series Subsystem consists of a 10" relay
rack with universal mounting backplane and a family of plug-in
(up to 16 per rack) input and output signal conditioning

designed to easily handle signal conditioning problems in
measurement and control applications. Some typical uses are in
microcomputer-based data acquisition systems, programmable
controllers, analog recorders, dedicated control systems, and any
other applications where monitoring of temperature, pressure,
flow and analog signals are required. Since each input module
features two simultaneous outputs, the voltage output can be
used to provide an input to a microprocessor-based data
acquisition or control system while the current output can be
used for analog transmission, operator interface, or an analog

The user-configurable Model 3B16-00 can be applied in
applications involving large tare weights which must be
compensated with zero suppression. The 3B16 protects the
computer side from damage due to field-side over-voltage faults
up to 130V rms. In addition, the current output withstands
130V rms without damage and interfaces user equipment
through screw terminals located on the 3B Series backplane.
The 3B16 is a plug-in, mix-and-match, hot-swappable module
which is easily field calibrated via front-panel zero and span
adjustments for both voltage and current outputs.
programmable Model 3B16-00, enables the user to configure a
special input range, including tare weight suppression, by using
the optional plug-on AC1310 ranging card, which houses user-
supplied resistors to determine zero and span. To facilitate
calculates resistor values based on the user-desired input/output
scale input voltage is subtracted from the input signal to set the
zero-scale value. Zero suppression can exceed 100% of the input
range. This is ideal for expanded-scale applications requiring
high-resolution measurement of a selected portion of an input
signal. For user convenience, the zero and span can be factory
configured to meet custom range needs (Model 3B16-
CUSTOM) or can be externally programmed (Model 3B16-00)
via user supplied resistors inserted in the optional AC1310 plug-

(-3dB) two-pole Butterworth filter enhances a 60 dB normal-
mode rejection at 50/60 Hz, enabling accurate measurement of
