This chapter gives 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 1761H module draws 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 1761H
Maximum Current Draw 350 mA
Table 2.1 Backplane Current Draw
Module Configuration
Figure 2.1 shows the location of the configuration jumpers on the 1761H module .When
shipped from the factory, all jumpers are installed. In order to access the J3-1 and J3-2 jumpers,
you must remove the left side panel. Jumper J3-3 is not used in this module. It is strongly
recommended that any modification to the J3 jumpers be made in a ESD safe environment. The
default configuration is: 180/1,800 Turn Transducer, Binary Position Data, Block Transfer.
