FEATURES

Isolated Frequency Input.

Amplifies, Protects, Filters, and Isolates Analog Input.

Generates an output of 0 to +5V proportional to input

frequency.

Model 5B45 accepts full-scale inputs from 500 Hz to 20 kHz.

Model 5B46 accepts full-scale input from20 Khz to 275 kHz.

Module circuitry can withstand 240v rms at the input screw-

terminals.

All 5B45 & 5B46 series modules are mix-and-match and Hot

Swappable.

APPLICATIONS

Industrial signal conditioning

Industrial signal isolation

Industrial signal filtering

PRODUCT OVERVIEW

The 5B Series represents an innovative generation of low cost,

high performance plug-in signal conditioners. Designed for

industrial applications, these modules incorporate highly

reliable transformer-based isolation and automated surface-

mount manufacturing technology. They are compact,

economical components whose performance exceeds that

available from more expensive devices. Combining 1500 V rms

continuous isolation, +0.05% calibrated accuracy, small size and

low cost, the 5B Series is an attractive alternative to expensive

signal conditioners and in-house designs

All modules are potted and identical in pin-out and size (2.27” x

2.32” x 0.595”). They can be mixed and matched, permitting

users to address their exact needs, and may be “hot swapped

without disturbing field wiring or power. The isolated input

modules provide 0 to +5V or +5V outputs and accept J, K, T, E,

R, S, N, or B type thermocouples.

These modules feature complete signal conditioning functions

including 240 V rms input protection, filtering, chopper

stabilized low drift +1 uV/oC amplification, 1500 V rms

isolation, and sensor excitation when required.

All modules feature excellent common mode rejection and

meet industrial transient surge withstand specifications.

Information furnished by Analog Devices is believed to be accurate and reliable.

However, no responsibility is assumed by Analog Devices for its use, nor for any

infringements of patents or other rights of third parties that may result from its use.

Specifications subject to change without notice. No license is granted by implication

or otherwise under any patent or patent rights of Analog Devices. Trademarks and

registered trademarks are the property of their respective companies.

There are also a number of backplanes and mounting sockets

which provide a complete signal conditioning solution for end

users. Each backplane incorporates screw terminals for field

wiring inputs and outputs and cold junction sensors for

thermocouple applications.

These signal conditioners are designed to provide an easy and

convenient solution to signal conditioning problems of both

designers and end users in measurement and control

applications. Typical uses include microcomputer-based

measurement systems, standard data acquisition systems,

programmable controllers, analog recorders and dedicated

control systems. The 5 B series modules are ideally suited to

applications where monitoring and control of temperature,

pressure, flow, rotation and other analog signals are required.

The 5B Series modules and backplanes are approved by Factory

Mutual (FM) and the 5B Series modules are approved by the

Canadian Standards Association (CSA) for use in Class 1,

Division 2, Groups A, B, C, and D locations. These approvals

certify that the 5B Series is suitable for use in locations where a

hazardous concentration of flammable gas may exist only under

fault conditions of operation. Equipment of this category is

called “nonincendive” and they need no special enclosures or

other physical safeguards.

The 5B series modules and backplanes have been tested and

passed the stringent heavy industrial requirements of the

European Union’s electromagnetic compatibility (ENC)

directive – EN50082-1 and EN50081-2. When used according

to installation directions (refer to 5B series User Manual), any

errors caused by EMI/RFI interference will be less than 0.1% of

the full scale 5B measurement range for field strengths up to 10

V/M and frequencies up to 1 GHz.
