2.2. Compact batch controller

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 mounted in a pipe in series with one or two valves, the batch controller makes it possible to carry out a dosing of

one or several quantities of liquids. The unit controls the opening of the valves and measures the quantity of the fluid

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

2.3. Universal flow transmitter

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

The transmitter can be associated with Bürkert flowmeter (e.g. Type 8020, 8030, SE30+S077). See chapter “10.3.

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

signal (pulse signal) can also be connected.

The transmitter operates on a 3 wire system and needs a 12…36 V DC or a 115/230 V AC power supply.

The transmitter is equipped with:

• an analogue output (4…20 mA current output, called AO1)

• a digital output (configured as a pulse output by default, called DO1)

• two totalizers.

Some variants are also fitted with two fully configurable relay outputs (called DO2 and DO3).

When connected to a flowmeter, the transmitter allows:

• through the digital or relay outputs

– to switch a solenoid valve

– to activate an alarm

– to generate a flow rate proportional frequency

• through the analogue output to establish a control loop.

2.4. Flow transmitter for “Low Power” flowmeters

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

The transmitter variant can only be associated with Bürkert flowmeter (e.g. Type 8020, 8030, SE30+S077) with sinus or

pulse output signal in a “Low Power” variant. See chapter “10.3. Combination of the remote device” on page 34

for more information.

The transmitter operates on a 2- or 3-wire system and needs a 12…36 V DC or a 115/230 V AC power supply.

The device is equipped with:

• an analogue output (4…20 mA current output)

• a digital output (pulse output)

• two totalizers.

Some variants are also fitted with two fully configurable relay outputs.

When connected to a flowmeter, the transmitter allows:

• through the digital or relay outputs

– to switch a solenoid valve

– to activate an alarm

– to generate a flow rate proportional frequency

• through the analogue output to establish a control loop.
