2、 Core functional characteristics
Source of Function Description
Analog output conversion converts digital control signals into analog signals and outputs them to the actuator
High current output supports standard current output (4-20mA) and high current output (20-320mA)
The TMR redundant architecture adopts triple modular redundancy (TMR) technology to ensure high reliability
The self diagnostic function module monitors its own current output, provides self calibration and module health information
The output data of the three channels in the channel voting mechanism is selected through voting to drive the output of the healthy channel
Loop feedback verification: Each channel has a current loop feedback circuit to verify the accuracy of the analog signal
Prevent non selected channel driving design to ensure that non selected channels do not drive analog signals to the field
Hot swappable support supports hot standby function, allowing for online replacement of faulty modules
Optimization of Turbine Control for Turbomechanical Control (such as Turbine Control) Optimization Design
