This chapter describes how to install the Series 1700 module into the I/O chassis.
It also give information on installing AMCI transducers. This includes information
on transducer mounting, shaft loading, and cable installation. Information on
interfacing Autotech transducers is also included.
Power Requirements
The 1700 modules draw power from the I/O chassis +5Vdc supply. The maximum current
draw is dependent on the number of transducer channels and is given in the table below. Add this
to the power requirements of all other modules in the chassis when sizing the chassis power supply.
Model Number 1731/1741 1732/1742 1733/1743 1734/1744
Maximum Current Draw
675 mA 700 mA 725 mA 750 mA

Installing the Module
Remove system power before removing or installing any module in an
I/O chassis. Failure to observe this warning may result in damage to the
module's circuitry and/or undesired operation with possible injury to
personal.
Install the module in a single slot
pair within the chassis. A slot
pair is two adjacent backplane
slots, the left of which is even
numbered. Most A-B chassis
have the slots numbered on the
backplane silkscreen. Figure 3.1
shows two modules. The module
on the left is installed correctly in
a single slot pair while the
module on the right is incorrectly
installed in two slot pairs.
All addressing and programming examples in this manual assume that the
module is installed in a single slot pair.
Keying Bands
Plastic keying bands can be inserted into the top backplane connector to prevent the
insertion of other modules. Insert the bands between the following pins:
hý
Pins 28 and 30
hý
Pins 32 and 34.
