Product Details

The XYCOM 8100-0272A is a discontinued brown out sensor and PROM memory board, designed for XYCOM CNC and legacy industrial control systems. This board integrates power-fail detection circuit and PROM storage components, it continuously monitors the input power supply voltage of the control rack, and triggers protection signals immediately once voltage drops below the preset threshold, to prevent program corruption, data loss and hardware damage caused by sudden power dips or brownout events. The onboard PROM chip stores fixed system firmware, parameter tables and boot configuration data, which retains critical system settings without power supply, supporting reliable cold start and system recovery for the CNC host. It adopts standard rack-mounted form factor and matched edge connectors, and can be directly inserted into the designated slot of XYCOM 8100 series control chassis. The sensor circuit has built-in voltage hysteresis filtering to avoid false triggering caused by instantaneous power fluctuation. The board supports stable coordination with the main CPU board and I/O modules inside the control rack, sending power alarm interrupt signals to the processor for timely fault handling. Technicians can verify the power detection threshold and read stored firmware data via on-board test points. The PCB is built with industrial-grade components and EMC suppression circuit, resisting electromagnetic interference and mechanical vibration in machine workshop environments for long-term stable operation. This legacy sensor PROM board is mainly supplied as spare replacement parts for existing XYCOM CNC equipment. Users need to confirm chassis compatibility, firmware version and connector pin definition before installation. A conformal coated version is optional for high humidity, dusty industrial sites. This model is widely used in CNC machine tool control systems, automated production equipment and old industrial control retrofit projects.

This brown out sensor PROM board adopts standard single-slot rack board structure. It draws power from the system backplane. LED indicators display power status 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 firmware and detection threshold configuration backup for fast recovery after hardware replacement.

This XYCOM 8100-0272A sensor PROM board is widely applied in legacy CNC control racks and industrial equipment upgrade projects. It provides power failure monitoring and non-volatile firmware storage for the host control system. As a reliable discontinued spare part, the XYCOM 8100-0272A retains original signal timing and firmware compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
