Multipump Control
The CFW08 version with multipump control board (A5 in the control board option in item 9 of the smart code) can control up to 4 pumps at the same time, keeping the output pressure constant, regardless of the flow demand. The CFW08 with multipump control board can also monitor the suction pressure and the source reservoir level, in addition to enabling the smart drive of the auxiliary pumps based on the running time.
Connectivity
Especially designed to integrate large industrial automation plants, the Fieldbus industrial communication networks provide advantages in the supervision, monitoring and control, generating high performance and great operating flexibility - ideal for applications on complex or integrated systems. The CFW08 can be interconnected to the industrial networks with worldwide used protocols: CANopen, DeviceNet, Modbus-RTU and Profibus-DP.
