Industrial Applications

1. Compact machine sequencing controller

Suitable for small packaging, assembly, or indexing machines that need 18 inputs and 12 relay outputs with AC mains power and local serial communication.

Problem Solved

Replaces relay logic with a compact PLC that can directly switch moderate field loads and coordinate simple machine states.

2. Retrofit controller for legacy equipment

Works well when modernizing older equipment that already uses AC supply and point-to-point serial devices, while keeping wiring changes minimal.

Problem Solved

Provides PLC control without requiring a full Ethernet-based redesign or 24 VDC control architecture.

3. Small multi-station I/O coordinator

Fits compact systems needing distributed expansion, local I/O growth, and coordination of sensors, counters, and simple actuators within the 150-point local limit.

Problem Solved

Supports scaling beyond the base unit through expansion while maintaining a small controller footprint.
