Micro Series batch controller is a powerful and highly accurate production
workhorse in the form of a compact 1/8 DIN panel meter. It can display the current batch
total (Item #1), grand total or number of batches (Item #2), and flow rate (Item #3). All
displayed values are scaled to engineering units of volume or flow.
The batch controller utilizes the Extended
counter main board and FR dual channel signal conditioner board to accept a wide range of
pulse signals, in particular those from turbine flowmeters. The same signal is applied in
parallel to the A and B channels.
A 8A contact relay serves as the batch relay to control repetitive fill operations.
It repeats the batch cycles continually with a programmable delay from 10 ms to 199.99
sec, or based on an external control input. The batch total (Item #1) can be set up to
count up from zero to a preset limit, or down from a preset limit to zero. The
single-relay board fits in the slot which would otherwise be available for the analog
An optional dual relay board (8A contact or 0.12 A AC/DC solid state
relays) is normally used. Either relay can be assigned to the batch total (Item #1) to
serve as a pre-warn to slow down filling near the setpoint, to the grand total or number
of batches (Item #2), or to flow rate (Item #3).
An optional RS232 or RS485 board allows the batch controller to transmit
Items #1, #2 and #3, as well as peak for #3 (rate). If required, all four items can be
displayed simultaneously by augmenting the batch controller with up to three
Micro 1/8 DIN
remote displays. Each of these can have its own analog output and dual relays for alarm or
Fast, High Accuracy
The A and B channels of the FR
dual-channel signal conditioner are used independently. Either channel can accept pulse
rates from 0.005 Hz to 250 kHz, which exceeds the working range of turbine
Channel A is used for
totalizing. The measured total is scaled mathematically for control and display in
engineering units, such as liters.
Channel B is used for rate.
The pulse frequency is determined by timing an integral number of periods over a specified
gate time (plus 30 ms and 0-2 periods), and then taking the inverse of period. The inverse
period approach allows much greater accuracy and faster update times than conventional
rate meters which count signal pulses over a specified time interval. Update times can be
as high as 25/sec. Rate in engineering units, such as liters per second, is obtained by
multiplying the input by a scale factor.
For either total or rate, displayed values can
be up to six digits (999,999) with a selectable decimal point.
Flowmeter Signal Conditioner
The FR dual-channel signal
conditioner accepts pulses from all types of turbine flowmeters and most industrial
transducers with a pulse output such as proximity switches with PNP or NPN output, TTL or
CMOS logic, magnetic pickup pulses down to 12 mV, as well as AC inputs up to 250 Vac. Jumper
selections provide optimum operation for different sensor types and noise
A built-in isolated 5, 10, or 24 Vdc
excitation supply can power proximity switches and other sensors, and eliminate the need
for an external power supply.
batch controller can be powered from
95-240 Vac ±10% and 95-370 Vdc, or
optionally from 12-34 Vac and 10-48 Vdc.
Any setup functions and front panel keys may be locked out for
simplified usage and security. The ability of the Micro batch controller
to drive an isolated 4-20 mA or 0-10 V output signal which tracks a
total may be unique among batch controllers.
DIN version with 0.56" high digits is environmentally sealed to
NEMA-4X (IP65) from the front when panel mounted, and is
available with red or green LEDs. All power and signal
connections are via UL / VDE / CSA rated screw clamp plugs,
which are standard.

Drum Filling Application Utilizing Three Relay Outputs
||In this drum filling application, the Micro
batch controller utilizes
its maximum of three relays to control the pump.
Prewarn relay slows down the pump near the preset to avoid overshoot. The Batch relay
stops the pump at the preset. The Grand Total relay stops the filling operation once a
predetermined number of drums have been filled.
Controlling the Mixing of Materials
||Multiple Micro batch controllers can be used in
combination to control the mixing of materials in the proper ratio. Each feed line is
equipped with its own pump, flowmeter, and Micro batch controller.
setup and monitoring of the mixing operation are facilitated by optional serial
communications. RS485 allows a single data line to handle multiple controllers.
Up-Counting Batch Control
||In up-counting batch control, the Micro
batch controller counts up from
zero to a preset maximum. A prewarn level is available to slow down filling near the
preset to avoid overshoot. A time delay can be programmed from the end of each batch to
the start of the next batch.
Down-Counting Batch Control
||In down-counting batch control, the Micro
batch controller counts down
from the preset maximum to zero. A prewarn level is available to slow down filling or
emptying near zero. Again, a time delay can be programmed from the end of each batch to
the start of the next batch.
Discrete Filling and Batch Counting
||The Micro batch controller is ideal for discrete
manufacturing as well as repetitive fill operations. In this example, the
bottles which it then groups into sixpacks. Its Grand Total capability can be used to
track bottles or sixpacks.
