I/O Interface Board ICB1H-S – OKUMA 1006-2121
The 1006-2121 is an I/O interface control board (“I/O Interface Control Board”), model ICB1H-S, manufactured by OKUMA for use in the OSP (Open System Platform) CNC control systems. The board manages the exchange of digital and analogue signals between the CNC control unit and machine peripherals (axes, spindle, field I/O), performing logical interfacing and signal level adaptation functions. It is documented as a component of the OKUMA control system across various CNC machine tool families (vertical and horizontal machining centres, CNC lathes, NC grinding machines).
The ICB1H-S board is the interface node that enables the OKUMA CNC to communicate with the power circuits and the machine’s sensors and actuators: without it, the control system cannot read machine states or issue commands to axes or spindle. A failure of this board causes an immediate machine shutdown, triggering I/O communication alarms and preventing any machining cycle from being started.
OKUMA Corporation is a Japanese machine tool and CNC system manufacturer founded in 1898, headquartered in Nagoya. It is one of the very few manufacturers worldwide to produce both machine tools and its own proprietary CNC control system (OSP – Open System Platform). Components from the older CNC series (OSP3000, OSP5000, OSP7000) are legacy / discontinued: available exclusively as used, surplus or through specialist repair.
