🔌 MASSO 6-Relay Module

Reliable Signal Control • Optical Isolation • Built-In Diagnostics

Take full control of your machine’s accessories with the MASSO 6-Relay Module, engineered for safe and efficient switching of high-voltage/current components. Designed specifically for use with the MASSO controller family, this compact and intelligent relay board features optical isolation for safety, multi-color LED status indicators, and support for both DC and AC loads—making it the ideal accessory interface.


✅ Key Features:

  • Optically Isolated
    Protects your MASSO controller and other low-voltage components by safely isolating high-voltage signals.

MASSO Relay module

Great product. PWN has the best price I found plus it shipped immediately. Great little relay module that integrated nicely. I mounted mine to a din rail PCB holder. ATC spindle control box almost done. Can’t wait.
