I/O linkage control is required for equipment start/stop, safety interlocks, and mutual exclusion logic. With the IOy I/O modules, these functions can be achieved without a PLC.
Case Details
Application Scenario
In factory automation, simple yet reliable I/O linkage control is often required for equipment start/stop, safety interlocks, and mutual exclusion logic. With the IOy Series Edge I/O modules, these functions can be achieved directly without an external PLC, ensuring quick configuration and fast response.
Typical Case:
On a production line, the following control logic is implemented using the IOy Series:
- Conveyor Start/Stop by Push Buttons
- When the operator presses the start button (DI1 closed), the conveyor motor (DO1) starts.
- When the stop button is pressed (DI2 closed), the conveyor motor (DO1) stops immediately.
When the safety door sensor (DI3) is open, the conveyor motor (DO1) is automatically shut down to ensure operator safety.
- Equipment Mutual Interlock
When Pump A (DO1) is running, Pump B (DO2) is prevented from starting, avoiding simultaneous operation that could cause pipeline shocks or energy waste.
Benefits
- No PLC Required: Built-in logic handles I/O linkage directly, reducing system cost.
- Fast Response: Hardware-level control with millisecond execution.
- Easy Deployment: Logic can be set through configuration software, no programming needed.
- Safe and Reliable: Ideal for on-site safety protection and interlock control applications.
