Additional signal circuits are required when it comes to expanding capacity in processing facilities with hazardous areas of food and beverage industries, like distilleries. These signal circuits depend on measured variables from the explosion-hazardous area being transferred to the control panel and, conversely, signals from the control system being transferred to actuators in the field. Hardware intervention at interface level can have an impact on plant availability. The task is always to keep this impact at the lowest possible level.
