520DuN, IP66 NEMA 4X model

This pump can be controlled from the keypad or remotely. It features:

Manual control

Speed adjustment; run and stop; direction control; keypad scaling; “max” key for rapid priming.

Remote control

The pump can be digitally controlled with a contact closure or logic input signal to operate the pump.

Analogue control

The pump speed can be controlled through an analogue signal input in the ranges 0-10V or 4-20mA. Scaling can be controlled similarly using Analogue signal input 2.

RS485 serial communication

Full pump control from a PC or other controller with the ability to network up to

32pumps.

Outputs

A 0-10V, 4-20mA or 0-1258Hz output signal provides feedback of the pump speed. There are four relay status outputs which can be configured in software for a variety of pump parameters.

MemoDose

Allows precise repeat dosing. Stores in memory a pulse count from the motor. This count is repeated each time START is pressed to provide a single-shot dose.

Calibration

Full calibration with default figures for a range of pumpheads and tubes. Calibration dose facility.
