KUC321AE HIEE300698R0001 electric actuators generally provide five signal points: one analogue signal to feed back the position signal of the electric actuator; two switching contact input signals to feed back the two limit alarm signals of the electric actuator; in addition, there are two forward and reverse coils drive interfaces for connecting the power devices, such as solid-state relays, thyristors, etc. The waiter or PAT module can then drive the solid-state relays or thyristors through the switching output signals to drive forward or reverse. In addition, there are two forward and reverse coil drive interfaces for connecting power devices, such as solid state relays and thyristors, so that the waiter or PAT module can drive the solid state relays or thyristors through the switching output signals to drive the electric actuators in forward or reverse rotation.

KUC321AE HIEE300698R0001 electric actuator applications are generally worse, and in the industrial field for the convenience of engineering implementation, the valve position feedback signal line, power supply line and the switching output signal line is concentrated in the same cable, the signal line crosstalk is serious, and thus the hardware of the PAT module must be in the isolation, anti-jamming, and electromagnetic compatibility to do strict design. Therefore, the hardware of PAT module must be strictly designed in isolation, anti-interference and electromagnetic compatibility.

KUC321AE HIEE300698R0001 module design adopts photoelectric isolation technology and electromagnetic isolation technology, analogue processing circuit is isolated separately, the switching part of the unified isolation. Switching output part and then through the solid state relay to achieve the isolation of weak and strong power, effectively overcoming the interference between different signals; at the same time and then in the analogue processing circuits, switching circuits to do further signal conditioning and protection measures, at this time, the PAT module has a very strong anti-jamming ability and good electromagnetic compatibility, stability and reliability has been significantly improved.
