FCS3*00 Three-phase (IP55)


The FCR3 devices are slave microprocessor controllers that manage three-phase asynchronous motors. The are mainly used to control condenser fan motors on refrigeration units. The control signal may be analogue 0 to 10 V, PWM, 0 to 20 mA or Modbus RTU over RS485 serial; the devices also feature a digital input and a digital output for alarm management. The serial port is used for remote supervision of all the parameters in the controlled system. Up to 255 addresses can be set on the Modbus network.
