ATEXIECExFMCSATR-CUSIL3

AC motor technology with single- or three-phase TENV motor, completely enclosed, non-ventilated squirrel cage construction and integral thermal overload protection.
Manual override available with sophisticated clutch/de-clutch mechanism.
Built-in phase reversal and failure detection in the power circuit.
Modern LCD display and configurable local selectors support local setup and operation.
Position and torque sensing use encoder position sensing and a torque sensor connected to the controller for feedback and logic.
Analogue control supports isolated setpoint and feedback signals.
Monitor and fault relays can be configured for multiple actuator conditions and status points.
Non-volatile EEPROM memory stores actuator settings and parameters; password protection is provided.
Optional Profibus DPV1, Modbus RTU, Foundation Fieldbus and Wireless HART communication are available.
Double-seal compartment protects electronic components from the terminal compartment.
