Industrial Applications

1. Labeling and Packaging Conveyor Synchronization

Utilizes the high-speed execution rate (0.08 µs/step) and built-in RS-485 Modbus RTU interface to synchronize labeling application speeds across multiple motor shafts. The integrated relay outputs can directly trigger packaging/pneumatic pushers.

Problem Solved

Eliminates the need for bulky external communication cards or premium-tier PLCs, reducing total panel size and component budget in machine designs under 100mm wide.

2. HVAC Air Handler and Damper Control

Controls ventilation damper actuators using the 6 relay outputs (2A) while communicating with master building management systems (BMS) over the long-distance RS-485 serial bus up to 1200 meters.

Problem Solved

Solves space limitations in wall-mounted electrical cabinets by providing a dense, narrow (25mm) DIN-rail form factor that includes both relays and serial communication ports natively.

3. Automated Liquid Dispensing and Valve Control

Orchestrates multi-valve dispensing steps in automated liquid filling lines. The PLC monitors up to 8 sensor inputs (e.g., proximity limits or float switches) and switches high-current solenoid valves directly via the 2A relay outputs.

Problem Solved

Saves wiring time and eliminates the physical failure points of intermediate terminal relays by switching 2A loads directly from the PLC terminal block.
