Field digital switching signals enter the module through front terminals. After passing over-voltage protection circuit and optoelectronic isolation, signals are shaped and filtered. The onboard logic circuit encodes valid signals and transmits data to DCS backplane bus. The main controller reads signal status in real time. The fault detection circuit monitors channel state and outputs alarm when open circuit or abnormal voltage occurs.
- Dual power supply compatibility, flexible adaptation to different field power conditions
- High channel isolation voltage, strong anti-interference for complex industrial environment
- High-density 16-channel design, save cabinet installation space
- Fast signal response, meet high-frequency signal collection requirements
- Native compatibility with Emerson Ovation DCS system, zero matching error
Thermal power generation, hydropower, petrochemical industry, chemical process, pulp and paper, municipal energy management
