MPN #: MRCU4AK
When a factory needs to run several robot arms at the same time, the control system often becomes a bottleneck. Slow or unreliable controllers cause production delays, higher scrap rates, and lost profit. You cannot afford downtime in a competitive market. The Oriental Motor MRCU4AK solves this by giving you a compact, four-axis controller that talks quickly with your robots and keeps every motion smooth and exact.
Take control of your automation line with a single device that can manage up to four robot axes. This controller is built for SCARA, palletizers, gantry carts and many other robot types. If you have struggled with mismatched wiring, slow response, or limited networking, this unit removes those obstacles. It uses Ethernet/IP, offers clear graphic monitoring, and fits into existing 24 V or 48 V power setups, so you can upgrade without a major overhaul.

We are retiring PICOPC Products MNHO-073, MNHO-048 and MNHO-043 and they have reached EOL (End Of Life) as we are introducing new products with better technology. We would recommend you to look into MNHO-095. For Untangle, pfSense, OPNsense, Windows 11, Proxmox VE etc. we recommend MNHO-095 whereas for Sophos, Kerio Control and Endian, we would recommend MNHO-069. (A complete list of supported OS can be found in each product's listing)
