PRODUCT OVERVIEW

The 3B Series of Signal Conditioning I/o Subsystems provide a

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

modules.

Eight and four channel backplanes are also available. Each

backplane incorporates screw terminals for sensor inputs and

current outputs and a 26-pin connector for high-level single-

ended voltage outputs to the user’s equipment.

The input modules feature complete signal conditioning

circuitry optimized for specific sensors or analog signals and

provide two simultaneous high-level analog outputs: 0 to +10V

(or +10V) and 4-20 mA (or 0-20 mA).

Output modules accept 0 to +10V (or +10V) single-ended

signals and provide an isolated 4-20 mA (or 0-20 mA) process

signal. All modules feature a universal pin-out and may be

readily hot-swapped under full power and interchanged without

disrupting field wiring.

The Analog Devices 3B Series Signal Conditioning Subsystem is

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

backup system.

Each input module is a single-channel signal conditioner which

plugs into a socket on the backplane and accepts its signal from

the input screw terminals. All input modules provide input

protection, amplification and filtering of the input signal,

accuracy of +0.1%, low drift of +1 uV/

C (low-level input

modules), and feature two high-level analog outputs that are

compatible with most process instrumentation. The isolated

input modules also provide +1500 V peak isolation.

The choice of a specific 3B module depends upon the type of

input signal. Input modules are available to accept millivolt, volt,

process current, thermocouple, RTD, AC and DC strain gage,

frequency and LVDT inputs. The voltage output of each module

is available from the system I/O connector while the current

output is available on the output screw terminals.

3B40 / 3B41

GENERAL DESCRIPTION

The 3B40 and 3B41 are wide-bandwidth (10kHz) single-

channel signal conditioning modules which amplify, isolate,

filter and protect analog input voltages and provide

simultaneous precision voltage and current outputs. Each

module performs complete signal conditioning, including

isolating (+1500 V peak input-to-output and power) and

protecting their computer side outputs from damage and loss of

signal integrity, and shielding their inputs from damage from

field-side over-voltage faults up to 220 V rms. The current

output withstands 130V rms without damage and interfaces

user equipment through screw terminals located on the 3B

Series backplane. Each plug-in, mix-and-match, hot-swappable

module is easily field calibrated via front-panel zero and span

adjustments for both voltage and current outputs.

3B Series Custom-Ranging Program – Externally-

programmable versions, Models 3B40-00 and 3B41-00, enable

the user to configure a special input range by using the optional

plug-on AC1310 ranging card, which houses user-supplied

resistors to determine zero and span. To facilitate selecting

resistors, a Windows program, 3B-CUSTOM, calculates resistor

values based on the user-desired input/output ranges.

A chopper-stabilized low-drift (+1uV/

C) input amplifier

assures long-term stability. At the amplifier input, a stable, zero-

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 (Models 3B40-

CUSTOM and 3B41-CUSTOM) or can be externally

programmed (Models 3B40-00 and 3B41-00) via user supplied

resistors inserted in the optional AC1310 plug-on ranging card.

Internal low-pass filtering with a 10 kHz cutoff (-3dB) is

determined by a two-pole Butterworth filter.

Signal isolation is accomplished by transformer coupling with a

proprietary modulation technique for linear, stable and reliable

performance. The differential input circuit on the field side is

fully floating, eliminating the need for any input grounding. A

demodulator on the computer side of the signal transformer

recovers the original signal, which is then filtered and buffered

to provide a low-noise, low-impedance output voltage: this

output also drives a voltage-to-current (V/I) converter to

provide a simultaneous current output for interfacing versatility.

With respect to the voltage output.

A wide range of custom zero suppression and span is available with the 3B40-00 and 3B41-00 models, using the AC1310 ranging card.

+24 V dc loop power is required for driving the current output at loads up to 850

Ω

. If a current output load of 400

Ω

or less is applied, +15 V dc is sufficient for loop power. If only

voltage output is used, loop power is not required.

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human

body and test equipment and can discharge without detection. Although this product features proprietary ESD

protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges.

Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
