*2.2. Equipment Monitored*/*Controlled by the Automation System*

The signals entering the automation system are given by temperature, pressure, and frequency sensors and the controlled equipment is represented by solenoid valves, fan, pump motors, electromagnets, an actuator motor, and a start motor impulse. Hardware components include connectors, input/output modules, PLCs with a processing unit, a multi-rack motherboard, and analog processing modules. Table 1 presents the main equipment to be monitored/controlled:
