The use of Renishaw or Renishaw-like electronic probes on articulated arm measuring machines calls for some modifications in order to correctly square the signal and avoid the rebounds generated by the electric contact. The "Trigger" board has been designed for the interfacing of such probes.

When the "normally closed" contact of the Renishaw probe is connected at the input, the board will output a perfectly squared and rebound-free "latch" signal, which will then be connected to the axis boards.

The 5V power supply can be provided by the "Master" board.
