Product Details

The XYCOM 81600EA1804 is a discontinued embedded CPU control board developed for XYCOM CNC and industrial automation control racks. It acts as the main processing unit to execute motion control logic, process axis position data, run system firmware and communicate with all peripheral I/O and servo interface boards inside the control chassis. This embedded controller integrates onboard memory, non-volatile storage for system parameters and boot firmware, and multiple serial communication interfaces including RS232 and RS485 to connect operator panels, servo drives and external debugging terminals. It uses the dedicated backplane bus to exchange high-speed data with signal interface boards, encoder feedback boards and analog control modules, supporting multi-axis coordinated motion control for machine tools. The board is equipped with configurable DIP switches and jumpers for setting station address, baud rate, boot mode and interrupt allocation to avoid resource conflicts in the whole control system. The front panel has LED indicators for power status, CPU running heartbeat and fault alarm, which help maintenance technicians quickly locate boot errors, communication failures and program exceptions during commissioning and daily maintenance. The PCB adopts industrial-grade electronic components and complete EMC filtering and surge suppression circuits, which can effectively resist electromagnetic noise, vibration and dust generated by spindle motors and inverters in machining workshops, and maintain stable long-term continuous operation. This legacy embedded CPU board is mainly supplied as spare replacement parts for existing XYCOM CNC equipment. Users need to verify firmware version, backplane pin definition and peripheral board compatibility before installation. A conformal coated version is optional for high humidity and dusty industrial machining sites. This model is widely used in CNC lathes, milling machines, machining centers and old CNC control system renovation projects.

This embedded CPU board adopts standard rack-mounted single-slot board structure. It obtains power supply from the control system backplane. LED indicators display power status, CPU activity and fault alarm for convenient on-site inspection. The operating temperature range is 0°C to 50°C, storage temperature ranges from -40°C to 85°C, relative humidity 5% to 95% non-condensing. It complies with industrial shock, vibration and EMC standards and has CE certifications. It supports system parameter and communication configuration backup for fast recovery after hardware replacement.

This XYCOM 81600EA1804 embedded CPU control board is widely applied in legacy CNC control racks and industrial equipment upgrade projects. It undertakes core calculation and scheduling tasks for the CNC control system. As a reliable discontinued spare part, the XYCOM 81600EA1804 retains original bus timing and firmware compatibility, and effectively reduces the renovation cost of legacy CNC control system maintenance.
