Product overview
The DLCA NET-ECAT is a DIN rail-mounted digital load cell
amplifier that provides excitation voltage for load cells,
measures the returned force signal, and then converts this
signal into a digital value that represents tension and analog
output signals.
The digital tension value is available in the fieldbus data on
EtherCAT. Configuration and calibration is available through
the fieldbus interface.
There are two models of the DLCA NET-ECAT, one senses
tension in one tension zone and the other senses tension in
two tension zones. Each one has two sensor inputs. Each
sensor input can have up to two load cells attached.
DLCA NET1-ECAT reads load cells from one tension zone
Channel 1 reads a single load cell or a tension-sensing
roller.
Channels 1 and 2 read two separate load cells,
respectively, in a single tension zone. This would typically
be the left and right load cells.
Tension values are sent from the load cells for the left and
right inputs. Two additional values are sent on the
communications interface; they are the sum and difference
of the left and right inputs (channels 1 and 2).
DLCA NET2-ECAT reads load cells from two tension zones
Channel 1 reads load cell(s) in one tension zone — one or
two load cells or a single tension-sensing roller per zone.
Channel 2 reads load cell(s) in a second tension zone —
one or two load cells or a single tension-sensing roller per
zone.
Tension values are sent from the load cells for each
tension zone.
The sum and difference values sent on the
communications interface are set to zero.
