Product Description:
Okuma Corporation of Japan manufactures the E7191-090-007 as a Docking Compact Rack. It belongs to the Okuma OPUS 7000 Series used in industrial automation. Its CNC application design makes this rack serve as a primary structural unit for capturing motion control components. The rack accepts multiple types of processor boards along with input/output communication modules.
The E7191-090-007 docking rack offers multiple communication interface points that include RS-232. It also has encoder feedback ports and axis module connection points. Logic circuits within the unit accept electric power from a 24V DC supply. The power usage quantity depends on the installed combination of boards and their type within the system. The differential signaling of the encoder interface provides exact control of motion operations. This unit is equipped with built-in heat dissipation vents for internal airflow. This PCB arm provides a passive connection of backplane with the inserted PCB boards. Inside cabinet installations are possible using this E7191-090-007 docking rack because its ingress protection level reaches IP20. The rack operates effectively between 0°C and 45°C of ambient temperature conditions. The control system withstands up to 85% relative humidity when the moisture does not condense. The complete rack weighs 6-8 kg, including its boards. The product shows resistance to shock and vibration forces that match industrial-grade mounting criteria. This unit allows users to mount it facing either vertically or horizontally within racks.
The E7191-090-007 docking rack maintains an electrical insulation resistance higher than 10MΩ for standard testing conditions. The compact frame holds multiple PCB slots with easy top-access latching mechanisms. Low-noise data transfer occurs through high-density PCB board connectors. The design adopts high-speed data transmission alongside low-latency improvement. The CNC system depends on this compact rack as its foundation for achieving precision along with operational efficiency and extended reliability.
