Product overview
The DLCA NET-S1 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
tension is displayed on the DLCA NET-S1 device.
The tension values have at least 14-bit resolution.
The digital tension value is available in the fieldbus data on Modbus
TCP/IP, Ethernet/IP or PROFINET IO. Configuration and calibration is
available through the fieldbus interface.
The DLCA NET-S1 is a two tension zone amplifier which subtracts a
portion of web tension on channel 2 from the roll weight on
channel 1. This is for a special weighing application in which the
roll weight is combined with a portion of web tension on channel 1.
The internal math prevents the web tension from
a
ffecting the roll
weight shown on channel 1.
Each sensor input can have up to two load cells attached.
Tension values are sent from the load cells for each tension zone.
Channel 1 is roll weight and channel 2 is the web tension. The sum
and difference values sent on the communications interface are set
to zero.
