Acrossser ARD 063B (k) CNC Relay Module

The Acrossser ARD 063B (k) CNC Relay Module is a compact interface that provides relay outputs to switch external devices from a CNC controller. It is intended for use with Acrossser’s ARD control family and serves as a centralized, plug‑in accessory to connect auxiliary equipment—such as coolant pumps, tool changers, air blasts, mist collectors, or spindle control circuits—to the CNC system. By relocating load switching to discrete relays rather than attempting to drive everything directly from the controller, the ARD 063B (k) helps organize wiring and simplifies integration in both retrofit projects and new CNC builds. The module is designed for easy mounting in standard control panels and offers straightforward wiring to common control signals and power rails, enabling reliable on/off control of connected devices in sync with the machine’s operations. For users planning expandability, this ARD relay board supports additional channels within the ARD ecosystem, allowing you to scale your automation without overloading the primary controller. As with all ARD accessories, verify coil voltages, contact ratings, and compatibility with your specific controller and power supply on the official ARD documentation before integrating into a live manufacturing workflow.
