Product Performance

Excellent signal acquisition accuracy: 16-bit AD conversion and high-precision calibration technology ensure that the measurement error of thermocouple, RTD and other signals is controlled within ±0.02% FS, meeting the high-precision monitoring needs of temperature, pressure and other parameters in industrial processes.

Outstanding anti-interference capability: 2.5kVrms high isolation design and electromagnetic shielding structure, with common-mode interference immunity up to 120dB, which can avoid signal distortion in industrial sites with dense high-power equipment and ensure stable data acquisition.

Efficient fault diagnosis: Real-time monitoring of abnormal states such as sensor open circuit and short circuit; triggers alarm and uploads diagnostic information within 100ms after fault occurrence; cooperates with LED indicators to quickly locate fault channels and reduce troubleshooting time.

Flexible system adaptation: Compatible with multiple sensor signal types, allowing access to different measurement equipment without replacing modules; supports redundant power supply and hot-swapping, enabling maintenance without system shutdown and improving equipment availability.

Convenient software integration: Seamlessly connects to ABB Control Builder M programming environment, provides pre-configured signal processing function library, enabling quick completion of channel parameter setting and data mapping, and reducing development cycle.
