Opto-Isolated Break-out Board.
Includes USB cable for Logic Side power.
Requires 12-24VDC for isolated side and for the PWM to analog signal.
P17 Is used to control the on-board relay.
P1 Can be used to control a PWM output (active low).
P10, P11, P12, P13 and P15 are optically isolated inputs.
P2, P3, P4, P5, P6, P7, P8, P9 generally used for STEP/DIR signals, are available at screw terminals. These are not isolated. They are buffered through HC245 circuits.
P1, P14, P16 and P17 are outputs and available at screw terminals and are also not isolated but are also buffered through HC245 circuits.
