Filed:
Nov 18, 2010
Appl. No.:
12/949304
Inventors:
Gregory D. Johnson - Urbandale IA, US

Abstract:
A control system for operating a device in a turbo machine system. The system includes a first programmable logic control device producing an analog output signal and a relay circuit electrically connected to the first programmable logic control device to receive the analog output signal. A field device is electrically connected to the relay circuit to receive the analog output signal to operate based on the analog output signal to provide a load. In addition, the relay circuit is electrically connected to a second programmable logic control device to communicate the analog output signal to the second programmable logic control device to monitor the analog output signal.
