Industrial Applications

1. Compact Conveyor Belt Sorting System

Automating material routing and speed monitoring on a short logistics conveyor line. The PLC reads inputs from photo-eyes and inductive proximity sensors to detect package size and presence.

Problem Solved

The 18 built-in digital inputs easily accommodate sensor signals, while the integrated high-speed counter inputs (up to 100kHz) read encoder feedback to synchronize pusher arms powered by the 12 relay outputs.

2. Small-Scale Packaging and Bagging Machine

Managing cycle timing, heat-sealing jaws, and filling processes on a vertical form-fill-seal (VFFS) machine.

Problem Solved

The 12 relay outputs (2 A switching capacity) directly switch the solenoids and contactors for heating elements and filling valves, operating on 100-240 VAC mains power without requiring external interposing relays.

3. Pump Alternation and Water Level Control Panel

Monitoring municipal or industrial tank levels and alternating dual-pump operations to distribute run-time wear.

Problem Solved

Leverages the 24 VDC auxiliary output (300 mA) to power multiple ultrasonic level transmitters. The 18 inputs handle float switches and pump run/trip signals, while the rugged IP20 DIN-rail design fits perfectly in standard motor control center (MCC) panels.
