Industrial Applications

1. Automated Conveyor Sorting System

Utilizes the built-in 100 kHz high-speed counter inputs to read pulse feedback from a rotary encoder, tracking conveyor speed and package position. The 18 digital inputs collect product identification signals from photoelectric eyes, while the 12 relay outputs switch pneumatic diverter solenoids and direct-on-line motor contactors to sort items.

Problem Solved

Provides real-time, high-precision distance tracking on moving sorting lanes and switches high-current actuators directly (up to 2 A) without requiring external signal isolation relays, saving DIN rail space.

2. Alternating Pump Station Controller

Performs duty-standby alternation for multiple industrial water pumps. Level switches monitor wet-well depth through digital inputs. The PLC cycles the pump run times to ensure uniform equipment wear and drives large motor starter contactor coils directly via its robust 12 relay outputs, while communicating station telemetry via the RS-232C interface.

Problem Solved

Eliminates premature wear on single pumps by automating wear-leveling control logic and switches inductive contactor coil loads reliably under a common 24 VDC industrial control environment.

3. Form-Fill-Seal Packaging Machine

Coordinates film feeding, bag sealing, and product dispensing. The CP1E reads registration marks on plastic film via quick-response digital inputs (with a 50 µs response time), measures bag length with encoder feedback, and actuates thermal sealing jaws and product dump gates using its high-capacity relay outputs.

Problem Solved

Maintains packaging alignment at high speeds by responding to photo-eye signals within microseconds, while directly controlling thermal jaw contactors and pneumatic valves from a single, low-cost platform.
