What is a LLC-BA Batch Controller?

The LLC-BA is a compact, easy to use batch controller designed as a central controller
for small to medium sized fluid batching systems. Nine different batch amounts can be
pre-programmed into long term memory and selected by the operator. Two relays provide
control for either single or dual stage valve operation. Two totalizers are available, one
acts as a batch totalizer and the other totals continuously with reset protection. The batch
counter has a user selectable option to either count up from zero or count down to the
batch amount. The unit’s smart programming automatically compensates for variations
from the selected batch amount. Inputs provide operator remote control for batch
selection, start, stop and reset.
