Introduction
This chapter introduces Field Control modules, the Genius Bus Interface Unit , and other
equipment that may be used with the Bus Interface Unit. It will help you locate more information
in other Field Control and Genius documents.
Overview
Field Control is a family of highly modular distributed I/O and control products. They are suitable
for use in a wide range of host ar ch i tectures.
The heart of the Field Contr ol system is the Bus Interfa ce Un it. The Bus Interface Unit pr ovid es
intelligent processing, I/O scanning, and feature configuration for a group of up to eight I/O
modules. Together, the Bus Interface Unit and its modules make up a Field Control station (see the
illustration, left).
The Bus Interface Unit and I/ O modules are enclosed in stur dy, compact aluminum housin g s. Bus
Interface Unit and I/O modules bolt securely to separate Terminal Blocks, which provide all field
wiring terminals. The I/O Terminal blocks are generic and allow different I/O module types to be
mounted on the same base. I/O Terminal Blocks are available with box-type terminals, barrier-type
terminals, or wire-to-board connectors. All Terminal Blocks must be mounted on a DIN rail. The
DIN rail, which serves as an integral part of the grounding system, can also be mounted on a panel.
