2.5. Remote batch controller

The device is available in wall-mounted and panel variants.

The device can be associated with Bürkert flowmeters (e.g. Type 8020, 8030, SE30+S077). See chapter “10.3. Combi-

nation of the remote device” on page 34 for more information. Another flow sensor emitting a frequency signal

(pulse signal) can also be connected.

The device needs a voltage supply of 12…36 V DC or 115/230 V AC.

The device is equipped with:

• four digital inputs (DI1 to DI4),

• two transistor outputs (DO1 configured as a pulse output and DO4 configured as state output, by default),

• two relay outputs (DO2 always configured to control the valve and by default parametrise of 100 % of the batch

quantity and DO3 configured as alarm output by default),

• two volume or mass totalizers and two totalizers for the number of batches performed.

The second relay output can be used to activate another valve, to initiate alarms or to generate warnings.

When the batch controller is connected to a flowmeter in series with one or two valves, dosing of one or several

quantities of liquids can be carried out. The device controls the opening of the valves and measures the quantity of the

fluid which flows. The device also closes the valves when the pre-set quantity has been delivered.
