The Harmony Input/Output (I/O) System interfaces field
inputs and outputs for the Symphony Enterprise Management
and Control System to monitor and control a process. The
Harmony I/O system incorporates a variety of input and out-
put devices (blocks) to interface process signals. Blocks for
analog, digital, and control I/O interface along with remote
I/O communication combine to create a complete I/O system.
The Harmony I/O system offers a complete solution in a mod-
ular, easy to use package. In addition to the I/O devices, the
Harmony solution provides many options for ready-to-use I/O
communications, I/O mounting, field wiring management,
power distribution, and cooling.
The Harmony I/O system is intended to be an alternative to
rack I/O modules and terminations. It provides flexibility in
system design, enhanced I/O signal processing, and reduced
installation complexity and installation time.
