Product Performance
- High – Precision Measurement: With a high – precision A/D converter and SIGMA – DELTA data conversion technology, it can accurately measure thermocouple and millivolt signals, with a measurement accuracy of up to ±0.03% of full scale (±24µV), ensuring accurate data for the control system and meeting the requirements of industrial applications with strict measurement accuracy.
- Strong Anti – interference Ability: Each input channel is electrically isolated, which can effectively resist external electromagnetic interference and ensure the stability and accuracy of signal transmission. It can also operate stably in complex electromagnetic environments, reducing signal distortion and misjudgment and ensuring reliable system operation.
- Reliable Fault Detection: It has a thermocouple burnout detection function, which can monitor the working status of the thermocouple in real – time. Once a thermocouple burnout is detected, it can promptly issue an alarm and take corresponding measures to avoid system out – of – control due to thermocouple failure and ensure the safety and stability of the industrial production process.
- Good Environmental Adaptability: With a protection level of IP65, it can operate stably in dusty, humid and other harsh environments. The operating temperature range is – 40°C to 85°C, adapting to the temperature conditions of different industrial sites and meeting the application requirements in various industrial environments.
- Convenient Integration and Expansion: It supports the Foundation Fieldbus digital bus protocol and can easily communicate and integrate with other devices that follow this protocol. It supports up to 8 input channels and has standardized communication protocols and interfaces, which are easy to integrate with other controllers, PLCs and industrial equipment, facilitating system expansion and upgrade.
