Working Principle
Amplifies and filters weak analog signals from field sensors, converts them into digital signals via high-precision A/D converters, and then performs linearization processing and engineering unit conversion through a microprocessor before transmitting to the controller via the internal bus.
Installation Requirements
Analog signal lines must use shielded twisted pairs, and the shield layer must be grounded at a single point on the control cabinet side to prevent ground loop interference.
Precautions for Use
Pay attention to signal polarity when wiring. For thermocouple or RTD inputs, ensure the compensation wire type matches the system configuration.
