Product Features

• High - precision Output: With a resolution of 16 bits and an accuracy of ±0.1% of span, it can provide accurate analog output signals, which is suitable for applications requiring high - precision control.
• Redundancy Design: It can be used in single or redundant applications. The redundant design can improve the reliability and availability of the system, ensuring that the system can still operate normally when a module fails.
• Self - diagnosis Function: The module performs self - diagnosis cyclically, which can detect faults in a timely manner, such as output circuit faults, power supply faults, etc., and provide corresponding diagnostic information for maintenance and troubleshooting.
• HART Communication Support: Supports HART pass - through communication, which can realize two - way communication between the field device and the control system, and facilitate the configuration, monitoring and diagnosis of the field device.
• Electrical Isolation: The electrical isolation between channels and ground can effectively prevent the interference of external electromagnetic fields and ground loops, ensuring the stability and accuracy of signal transmission.
