Product Performance
Output accuracy is excellent: 12-bit resolution combined with ±0.1% nonlinear error ensures analog signal generation accuracy meets industrial precision control requirements; independent D/A converters per channel eliminate cross-talk between channels.
Configuration flexibility is strong: Multiple ranges are switched directly via software programming without hardware adjustment; dual-buffered output supports parallel operation of signal update and output holding, adapting to real-time signal switching needs in dynamic regulation scenarios.
Operation reliability is outstanding: Automatic calibration function ensures long-term operation accuracy stability; comprehensive onboard diagnosis and self-test system can quickly locate faulty channels; offline test mode reduces system maintenance downtime.
System integration is efficient: Standard VMEbus interface seamlessly adapts to GE Fanuc VME series industrial computers and DCS systems; address jumper setting is simple, supporting fast communication with various main control modules.
Environmental adaptability is excellent: -40℃ to +85℃ wide temperature range covers high and low temperature industrial scenarios; IP65 protection rating and anti-electromagnetic interference design ensure stable operation in dusty, humid and high-power equipment-dense environments.
