Installing the Smart Transmitter
Interface Products
This chapter explains how to install the Smart Transmitter Interface
products. It includes the following information:
an overview of the general installation procedure
how to connect the Communications Controller and Terminal Blocks to
each other so they can communicate
how to connect Terminal Blocks to Analog I/O and HART field devices
system grounding requirements
power supply requirements and connections for the Communications
Controller and Terminal Blocks
how to provide power for HART field devices through the Terminal
Blocks
how to connect the Communications Controller to the host processor
Before installing the Smart Transmitter Interface you should:
determine where the Communications Controller and Terminal Blocks
are to be placed
The Terminal Blocks should be mounted in the same equipment cabinet
as the Analog I/O modules to which they are to be connected. The
distance between a given Terminal block and its HART field devices
must conform to the HART Protocol specifications and meet the
requirements in Appendix C.
review your setup to ensure that the maximum cable length between the
Communications Controller and the Terminal Blocks is not exceeded.
See the section Connecting the Communications Controller to the
Terminal Blocks for details.
calculate the power requirements of the Communications Controller
(1770-HT1), the Terminal Blocks (1770-HT8/16) and the HART field
devices
