7B SERIES BACKPLANES

7B Series Overview

All Series Modules

General Description

To complement the 7B Series signal conditioners, Analog Devices offers a variety of multi-channel backplanes and a single-channel DIN rail mount mounting card,

designed for 7B modules. Backplanes are presently available in 4-, 8- and 16-channel configurations (model numbers 7BP04-1, 7BP08-1 and 7BP16-1, respectively). The

7BP04-1, 7BP08-1 and 7BP16-1 backplanes may be mounted in a 19" x 3.5" panel space via rack-mount hardware kit (Model AC1363) available from Analog Devices. The

backplanes are also designed to mount on a flat surface with standoffs provided with each backplane - mounting screws are provided with the

smaller applications, the single channel mounting card, model AC1387, is provided with DIN rail mounting hardware.

Field and System Connections

Field connections for transducers/signal inputs, 2-wire transmitter loop power inputs and current outputs, are made through a three-screw terminal block - refer to the Field

Connection figures shown in each model section. On all backplanes, the interface to the user's system is accomplished by a standard 25-pin D-type connector. Two

identical 25-pin male connectors located on the backplanes provide a means of optionally having separate input and output connections when input and output modules are

being used on the same backplane. Figure 1 illustrates the functional block diagram for the Model 7BP16-1 backplane, indicating the terminal designations for the power

supply and field connectors. On the AC1387 mounting card, system interface is made with screw terminal connectors.

Application Flexibility

To insure the reliability of the module's electrical connection to the backplane, gold-plated sockets are provided on each channel. To accommodate thermocouple signal

inputs, a miniature cold junction compensation (CJC) thermistor is mounted under the input terminal block of each backplane and mounting card channel. The thermistors

are embedded in the circuitry under the I/O screw terminal blocks and are not visible on the backplane or mounting card. For users constructing their own backplane or

mounting card, the thermistor is commercially available from the manufacturer, Betatherm Corp., part number 100K6A1. Refer to the 7B Series User manual for additional

information. In addition to the CJC temperature sensor for each input channel on the backplanes, a pair of pin sockets permits installation of the

resistor used with the Models

Powering Flexibility

The 7B Series are powered by a single +24 V dc power supply. Linear supplies, whether regulated or unregulated, are recommended. Most modules operate between +14

Vdc and +35 V dc. Four screw terminals are provided on the backplanes to allow several ways of supplying power to the 7B Series backplane. Figure 2 defines the terminals

and illustrates how a redundant power supply scheme can be implemented. As illustrated, three power supply terminals are provided for connecting the high side of the

power supply to the backplane. This allows three different connection schemes.

1. A single power supply can be connected to either V+A or V+B terminals.

2. Redundant supplies are connected to V+A and V+B terminals.

3. A low voltage power supply of +14 V dc or +15 Vdc can be connected to the V+ terminal, thereby avoiding the voltage drop across the diodes that are in series with the V+A

and V+B terminals.

The backplane diodes serve two purposes. One is to provide the means of switching redundant power supplies; the other is to protect 7B Series modules from a reverse

polarity connection. A single LED on each backplane indicates the power ON status.
