Each channel can independently configure the output range,bias value and rate limit,and supports user-defined control logic,such as cascade control or characteristic compensation through SP selector(SPSELECTOR).
Anti-interference ability:
An isolation circuit is designed for power grid interference(such as common mode voltage)and space electromagnetic radiation,which effectively reduces noise during signal transmission and reduces the risk of system failure.
Status monitoring and diagnosis:
Integrated status indicator light,real-time feedback on the operating status of each channel,combined with fault alarm function,simplifies the maintenance process.
3.Typical application scenarios
Industrial automation:
In process industries such as pulp and paper,chemical industry,and power,it is used to control analog parameters such as inverter frequency and valve opening to achieve precise adjustment of the process.
