Product Details

The XYCOM VME-70661-714 is a discontinued 6U VME bus analog input board, developed for XYCOM VME chassis and legacy process control systems. This module is built for high-precision analog signal collection, converting analog voltage and current signals from field transmitters and sensors into digital data that the VME bus master CPU can read. It integrates multi-channel signal conditioning circuits, programmable gain amplifiers, high resolution ADC, anti-aliasing filters and surge protection circuits. These circuits filter out electromagnetic noise from inverters, pumps and servo equipment on site to guarantee stable and accurate sampling results for closed-loop control and data logging. The board communicates with the host controller following standard VME bus protocol, supporting interrupt triggering and block data transfer for high-speed acquisition. Users can configure channel range, sampling speed and interrupt level through on-board DIP switches and jumpers, avoiding address conflicts with other VME modules installed in the same rack. The front edge is equipped with LED indicators for power supply, bus access and channel fault alarm, allowing maintenance technicians to quickly check power failure, bus timeout and signal wiring errors during commissioning and routine inspection. The PCB uses industrial-grade components and full EMC protection design, which can withstand vibration, dust and temperature fluctuations in chemical plants, power stations and machining workshops. This legacy VME analog input board is mainly provided as spare replacement parts for existing XYCOM distributed control systems. Users need to verify VME chassis compatibility, bus address allocation and signal wiring range before installation. A conformal coated version is optional for high humidity, dusty and corrosive industrial environments. This model is widely used in temperature and pressure monitoring, flow process control and old VME automation system retrofit projects.

This vme analog input board adopts standard 6U VME rack mount structure. It draws power from the VME backplane. LED indicators display power status, bus 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 channel configuration and bus parameter backup for fast recovery after hardware replacement.

This XYCOM VME-70661-714 analog input board is widely applied in legacy VME control racks and industrial process monitoring upgrade projects. It provides reliable analog signal acquisition for the master control system. As a reliable discontinued spare part, the XYCOM VME-70661-714 retains original VME bus timing and signal compatibility, and effectively reduces the renovation cost of legacy industrial control system maintenance.
