Control Unit type CCU with relay output

• The control unit is a Clean Control unit designed to control and regulate an automatic filtration process using filter units supplied by GEFA Processtechnik GmbH.
• When the supply voltage is applied (230 V / 110 V), the control unit is ready for operation.
• The power supply should be disconnectable by means of an upstream protective fuse or suitable circuit protection device.
• The standard enclosure protection rating is IP44. IP67 is available as an option.
• A contactor must not be switched directly. A contactor may only be operated in conjunction with an interposing relay.
• The filter control unit is suitable for continuous operation.
• The filter control unit has been developed specifically for use with filter units supplied by GEFA Processtechnik GmbH. GEFA Processtechnik GmbH assumes no warranty or liability for the operation of third-party filter products in combination with this control unit.
• As standard, the filter control unit is equipped with integrated pressure sensors for differential pressure measurement. The sensors are designed for a maximum pressure of 10.00 bar.
• The power supply is 230 V / 110 V, 50 / 60 Hz, with an integrated 24 V AC transformer.
• The control unit has a modular design and can control between 1 and 10 filters, depending on the configuration. As standard, one plug-in module with 2 outputs is supplied. Up to 4 additional plug-in modules can be installed as an option.
• Only 24 V AC solenoid coils may be connected.

Alarm Relay

• The alarm relay provides a volt-free (potential-free) signal.
• The alarm relay is activated if an error or fault occurs. The corresponding error message is shown on the display.
