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 architectures.
The heart of the Field Control system is the Bus Interface Unit. The Bus Interface Unit provides
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 sturdy, compact aluminum housings. 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.
