Overall Dimensions: 172.7mm×114.3mm×60.35mmHousing Material: Flame-retardant engineering plastic (UL94 V-0 grade) with RFI shielding functionWeight: Approximately 0.6kgMounting Method: Standard VMEbus slot mounting, compatible with 6U VME standard chassisWiring Method: Supports terminal wiring and shielded cable access, directly connectable to VMIC signal conditioning circuit boards

Product Performance

Signal acquisition accuracy is high: 16-bit resolution combined with programmable gain control ensures digital error of analog signals in different ranges is controlled within industrial precision levels, adapting to weak signal acquisition needs such as thermocouples and strain gauges.

Channel configuration is flexible: 64 high-density input channels support differentiated scanning grouping, channel block size and buffer capacity can be selected on demand, balancing acquisition efficiency and data storage needs.

Data processing is efficient: Dual-port data buffer enables parallel operation of acquisition and reading; onboard timer and interrupt function reduce host intervention, allowing a single module to independently complete large-scale continuous data acquisition.

System expansion is convenient: Supports synchronous scanning startup of up to 16 modules, enabling the construction of 1000-level channel data acquisition systems; compatible with standard VMEbus master control devices, integrable into existing systems without additional adaptation.

Operation reliability is strong: Wide-temperature design and multiple protection functions adapt to harsh industrial environments; anti-electromagnetic interference characteristics ensure distortion-free signal acquisition in high-power equipment-dense scenarios, with continuous operation without interruption.
