Abstract: A oil and gas compression system is generally presented. The compression system includes a driver, a driver starter, and an input expansion unit. The expansion unit may include a plurality of inputs configured to receive feedback from the compression system, a processor configured to receive the plurality of inputs and send an output signal to the driver starter to start or stop the driver, and an indication panel configured to indicate the presence of an input condition. The input expansion unit may be configured to store a history of received input conditions and display the history on the indication panel upon request.
