E3EFA HENF452750R1

Real time acquisition of three-phase motor current
Onboard multi-channel current transformer, synchronously collects the three-phase working current of the motor, converts the load rate and imbalance, and uploads it in real time to the E3EB main control and DCS upper system;
Multi level motor hardware protection logic
Built in overload, phase loss, current imbalance, and motor stalling four fold self-locking protection, instantly blocking the driving pulse in case of a fault to prevent high-power motors from burning out; Supports manual/automatic reset modes;
Local fault indication and remote upload
The panel integrates a RUN running green light and a FAILT fault red light. The fault code is synchronously uploaded to the HMI through the MasterBus300 backplane bus, and the current and duration of the fault are recorded;
Full channel electrical isolation and anti-interference
Triple optoelectronic isolation of current collection circuit, backplane communication, and on-site interlocking signals to resist strong electromagnetic interference from rolling mills and high-power frequency converters in power plants;
Rack hot swappable maintenance
Standard Advant card size, cabinet replacement without stopping, matched with Control Builder software for online setting of motor rated current protection threshold;
PCB standard three proof conformal coating
Moisture proof, dust-proof, and slightly corrosion-resistant, suitable for high dust and high humidity control cabinet working conditions in thermal power, metallurgy, and chemical industries.
