Student view
How to understand this product.
Learn how a control panel maps physical switches, sensors and actuators into software signals.
What you can learn
- Digital IO mapping
- Panel documentation
- State-machine logic
- Time-based automation
A simple project flow
- Assign each terminal a named signal.
- Read inputs and evaluate a rule.
- Change outputs and show status on the LCD.
Real-world applications
Example projects showing what this product can read, control and report. Each requires the appropriate sensors, connected equipment and application software.
Packaging-machine signal panel
Example: connect compatible part-present switches and machine-state signals to assigned digital inputs. Program a sequence that reads those states and drives suitable indicators or actuator-interface circuits through the configured outputs.
Building status panel
Example: collect dry-contact or otherwise electrically compatible status signals from rooms and service equipment. Display named states on the LCD and use configured outputs for local indicators or suitable control interfaces.
Automation training bench
Example: wire low-voltage push buttons, switches and indicators to documented IO channels. Students implement a sorting or sequencing exercise, then use the LCD menu to inspect states and practise fault finding.
