M41K I/O Interface Board

The M41K is ExtraTech's main interface board. It comes in 3 flavors, T2, T3 and T4, to fit your mounting and operating needs. All the flavors have some common components and features. . .

  • 8 Optically Isolated Solid State Relays
  • 8 Optically Isolated Limit Inputs
  • Ribbon cable for interfacing into the M60.
  • Identical Board Shape, size and software interface.

The T2 is the more generic flavor that is intended to be and easy upgrade from the M40. On the T2, all terminal connectors are vertical and Step and Dir are supported through 2 terminal blocks and the M60 ribbon cable. The T2 can be sandwiched between the M60 and the controller board, however, due to the fact that some of the connectors are vertical, the over all board stack height will be taller than a T3. Power input is handled via the terminal connector P1 or the M60 ribbon cable.

The T3 is a higher end board designed to minimize overall stack height when used with the M60. The T3 is a fully populated and more expensive version of the M41K. All connectors on the edge of the board are horizontal and all connectors towards the center are vertical. Terminal blocks are supplied for step and dir signals if the application doesn't use an M60, or if the application calls for more than 4 motors. The analog portion of the circuit is populated, which supplies an isolated 0 to 5 volts, or 0 to a variable voltage up to 10 Volts.  This output can be controlled by the DAC software port, or by the laser control circuitry (for analog lasers.)

The T4 is a fully populated board like the T3, with all connectors vertical (like a T2).

The M41K supports two X's, two Y's, three Z's and 1 theta / Q axis  (T2 and T3). In order to provide laser raster tracking information to the controller board, an encoder channel is also provided. These Step and Dir signals have many configurable options, contact us for details.

Limits can be set for latched or real-time input and are filtered for some noise.
