Core Functions

1. Digital‑Intensive Control: 24DI/16DO for conveyor systems, material handling, assembly lines.

2. Larger Memory: 256 KB Flash supports more complex logic than 07KT95.

3. Distributed I/O: CS31 bus expands to remote modules for larger systems.

4. High‑Speed Pulse Input: 20 kHz counter for encoders, flow meters.

5. Modbus RTU: Connect to HMIs, sensors, other PLCs.

6. Harsh‑Environment Ready: Optional conformal coating (like 07KT95C/F) for dust/moisture.

Application Scenarios

• Conveyor & Material Handling: Packaging lines, airport baggage systems.

• Assembly Stations: Automotive, electronics (digital sequencing, interlocks).

• Textile & Plastics: High dust, digital machine control.

• Food & Beverage: Dry processing areas (no analog needed).

• General Machinery: Punching, bending, cutting machines.
