External analog signals from field sensors enter AI channels, pass through isolation, filtering and amplification, then complete AD conversion and transmit digital data to the control system. The control system sends control data to AO channels, which complete DA conversion and signal conditioning, and output standard analog signals to drive field regulating equipment.
- Integrated 4AI+4AO design, high integration to save cabinet space
- Two universal signal types configurable for each channel
- High conversion resolution and high signal accuracy
- Full channel isolation, strong anti-interference ability
- Wide temperature range, suitable for general industrial sites
Chemical industry, energy and power, heating ventilation, environmental protection, hydraulic control, industrial furnace equipment, process automation
- Mount on standard 35 mm DIN rail inside control cabinet
