Rate of Change Option
The ROC option measures and displays the rate at which a material enters or is dispensed
from the scale over a period of time. ROC data uses a 110-entry register. New weight values
are written to the register at the rate of 1/110th of the time base. The first register is
subtracted from the 111th Register, which is one time base older than the first register. The
time frame can be set to units per second, minute, or hour. A time base of discrete values is
selectable from 1 to 1800.
Analog Output Option
Each of four independent analog outputs per option card is configured from the front panel
or the embedded web server. Two outputs are voltage and two are current. This option
allows the transmission of gross, net, available Rate-of-Change (ROC) or “mapped”
weight. Mapped weights can be 0-5V or 0-10V on the voltage outputs and 0-20 mA or 4-
20 mA on the current outputs. It also is possible to span these ranges over a portion of the
weight data with a resolution of 16,000 counts for each channel. All parameters can be
mapped to these Analog Outputs.
NOTE The analog output is not isolated. An external 4-20 ma isolator may be required for stable
readings.
Digital I/O Option
While the standard HI 4050 includes three built-in external digital inputs, the digital I/O
card option adds three more digital inputs (isolated) and four digital outputs (non-isolated).
