Sense and Control – Industrial

The Matrix Sense and Control for industrial maintenance, along with a PLC LOGO! Module introduces learners to core concepts in industrial automation and programmable control in a compact, self-contained system. Designed around the Siemens LOGO! PLC and the versatile Locktronics platform, the module enables hands-on exploration of PLC programming, control logic, and real-world I/O systems.

The integrated LOGO! controller provides both wired and wireless connectivity, supporting program upload via MicroSD. Students can control logic-driven outputs and view system feedback using a PC, mobile device, or built-in display.

Experiments are built around modular components mounted to a Locktronics pillar board. Each component such as input switches, indicator lamps, sensors, and relays is secured using quick-release connectors for fast configuration and testing.

This curriculum supports exploration of control systems, input/output devices, logic operations, and troubleshooting.

By the end of this course, learners will be able to:

• Distinguish between analogue and digital sensors.
• Understand that simple digital sensors have a two-state output: open (off) or closed (on).
• Recognize that digital sensors exhibit high resistance when open and low resistance when closed.
• Identify that digital sensor outputs are typically either 0V or the full power supply voltage.
• Recognize and understand circuit symbols for a range of switches, bulbs, and sensors.
• Appreciate that some components are polarized and must be connected correctly.
• Program a controller to recognize a high input voltage as an ‘on’ or ‘off’ signal.
• Understand output device requirements in terms of current, and the use of relays for higher current delivery.
• Understand the advantages of transistors over relays for faster switching.
• Connect a control unit to deliver current through transistor and relay outputs.
• Understand systems as comprising three core elements: input, process, and output subsystems.
• Recognize that analogue sensors provide a continuous range of voltages.
• Use a potentiometer to set a reference voltage for parameters such as temperature.
• Differentiate between open-loop and closed-loop control systems.
• Simulate an analogue voltage using a square wave with a varying duty cycle (PWM).
• Understand that analogue sensor signals may require scaling or conversion to be meaningful.
• Program and control PLCs using different programming languages and methods.
