The 7I76 is a daughtercard/breakout board  for use with MESA's 25 pin I/O FPGA cards like the 5I25 and 5I26.

The 7I76 is designed for interfacing  up to 5 Axes of step & direction stepper motor or servo motor drives and also provides a spindle encoder interface, isolated analog spindle speed control and 48 isolated I/O points for general purpose field I/O use. All step and direction outputs are buffered 5V signals that can drive 24 mA.

All outputs support differential  mode to reduce  susceptibility to noise. An isolated analog spindle voltage with direction and enable outputs is provided for spindle control as is a single spindle encoder channel with TTL or differential inputs. 48 points of isolated field I/O are provided for general control uses such as limit switches, home position switches, control panel inputs, coolant enable and tool changer control outputs.  Isolated I/O includes 32 sinking inputs and 16 sourcing outputs. Inputs can sense 5V to 32V signals and the outputs can switch 5V through 28V signals.  Maximum output load is 300 mA. Outputs are short circuit protected. In addition to the being able to read digital on/off status of each input,  four input pin voltages are readable with 8 bit resolution, and  two MPG encoder inputs are provided as an option on four  field inputs. Field I/O is powered by an isolated 10-32V field power source. One  RS-422 interface is provided for further I/O expansion via a range of serial I/O daughtercards.  All field wiring is terminated in pluggable 3.5 mm screw terminal blocks.
