Industrial Applications

1. Rail vehicle signal isolation for 12 V control circuits

Use this module to isolate low-voltage control signals from downstream DC loads in railway auxiliary panels where compact spacing is critical.

Problem Solved

Prevents control-side interference and reduces panel footprint in rail-rated installations.

2. Dense PLC output interfacing for small DC loads

Suitable for high-density control cabinets where a PLC or controller needs a compact interface stage to switch DC loads up to the module’s output range and current limit.

Problem Solved

Converts control logic into a protected field-side switching interface without occupying large panel area.

3. Retrofit of legacy control cabinets with space constraints

Ideal for upgrading existing electrical cabinets that require a slim interface module with standardized wiring and visible status indication.

Problem Solved

Adds isolated switching functionality without reworking the cabinet layout or sacrificing terminal space.
