Key Features:
- High-precision signal processing supports multiple analog signal types, including thermocouples, RTDs, 4-20mA current, and 0-10V voltage signals
- Flexible channel configuration with 8 input channels that can be grouped for independent signal type, range, and sampling rate settings; channel-level fault isolation prevents cross-channel interference
- Multi-layer anti-interference design with photoelectric isolation, EMC optimization, and built-in filtering to ensure stable signal transmission in high-electromagnetic environments
- Industrial-grade reliability with wide-temperature components, overvoltage/overcurrent protection, anti-corrosion PCB coating, and real-time fault self-diagnosis with alarm functions
- High sampling and update rates: up to 100ms per input channel, 50ms per output channel for fast-response applications
Applications:
- Power industry: Boiler control, photovoltaic inverter monitoring, hydropower turbine control
- Chemical industry: Reaction kettle parameter control, distillation tower process regulation, waste gas treatment system management
- Metallurgy industry: Converter steelmaking control, non-ferrous metal electrolysis process monitoring, rolling mill thickness adjustment
- Water treatment industry: Municipal water supply parameter collection, sewage treatment process control, industrial wastewater quality monitoring
