Flexible input levels support 5V drivers for broad hardware compatibility. For engineers maintaining legacy systems, the v1

For engineers maintaining legacy systems, the v1.1 is a drop-in replacement for the D302 pin-out, meaning no rewiring of the backplane is required. This isolation is critical, as it protects your

The "D302" or "D402" moniker typically refers to specific hardware revisions or models sold by different vendors (such as Sainsmart) but shares the same fundamental design and function as the BL-MACH-V1.1. It is an opto-isolated board, meaning it uses electronic components called optocouplers to electrically separate the computer's circuitry from the machine's power components. This isolation is critical, as it protects your computer's sensitive motherboard from dangerous voltage spikes or electrical noise generated by the CNC's motors and power supply.

Five input interfaces allow for the connection of limit switches , emergency stops (E-Stop), or tool setting probes.
