Industrial Applications

1. Compact machine control panel integration

Used in small machine panels where 24 VDC control power, 24 inputs, 16 outputs, and a compact 150 × 80 × 90 mm footprint are needed.

Problem Solved

Reduces panel space while providing enough onboard I/O for discrete machine control without an external remote I/O system.

2. Serial-connected production equipment control

Fits equipment that must communicate through RS-232C or RS-485 to drives, HMIs, printers, or legacy devices while maintaining local control logic.

Problem Solved

Eliminates the need for a separate gateway or serial interface module for basic serial integration.

3. Indexing or pulse-based small motion applications

Suitable for small motion or indexing machines that require pulse outputs up to 100 kHz, encoder feedback channels, and up to 2 PTP axes.

Problem Solved

Provides integrated motion-adjacent control for simple positioning without a larger motion controller.
