Powering the MASSO Touch

The MASSO Touch power supply connector is located at the top-right corner of the controller as seen in the picture below. MASSO Touch requires a power supply of 24 VDC with a minimum of 1.5 Amps output. MASSO Touch will power on instantly once power is connected.




WARNING: The installation of a 1 amp fuse between your Power Supply and MASSO is required to protect against an accidental short circuit of the auxiliary power connectors on MASSO, such an event can damage the controller beyond repair.


INFORMATION: There are multiple Power (Red-colored) and Ground (Black-colored) provided on the controller and can be used to easily wire drives, sensors and switches.


Some examples:


  • The Power terminals can be used to provide voltage to sensors or switches for machine homing.
  • The Ground terminals can be used to wire common ground signals between stepper or servo motor drives.


CAUTION: Power and Ground terminals provided on the controller are only to be used for very low current signals. Connecting high current loads can damage the controller beyond repair.
