Connectivity
The HI 4050 enables operators to use the selectable10/100 Base T Ethernet port and its
embedded web server to link performance, diagnostics and setup data to and from your
Intranet, Extranet, VPN or the Internet. The available communication interface lets you
view and control multiple applications from a display and add third-party I/O to the system.
A single RS-232 serial port is configured as a printer port.
Digital I/O
Digital inputs are used to either signal a change in state or send the commands to tare, zero,
or calibrate the instrument. Two setup options provide alternatives for application-specific
requirements. The standard option uses only the HI 4050’s three built-in external digital
inputs, which are sufficient for many applications.
Mapped I/O
Mapped I/O saves wiring costs by distributing the I/O where you need it, at the process or
in the control room. Available interfaces provide communications to PLC, DCS or
computer controlled systems.
WAVERSAVER
®
Mechanical noise (from other machinery in a plant environment) can be present in forces
larger than the weight forces being measured. The HI 4050 is fitted with WAVERSAVER
technology that eliminates the effects of vibratory forces present in all industrial weight
control and measurement applications. By factoring out almost all of the ambient vibratory
forces, the controller can separate out the actual weight data.
WAVERSAVER can be configured from the front panel to ignore noise with frequencies as
low as 0.25 Hz or as high as 7.0 Hz. One of five higher additional cut off frequencies can
be selected to provide a faster instrument response time. The default factory setting is 1.00
Hz vibration frequency immunity.
WAV
WAV is a superset of WAVERSAVER for the HI 4050+ that uses two
additional parameters,
variation_thd and motion_thd, to configure an adaptive filtering
algorithm, which significantly improves the stability and accuracy of the weight reading.
C2
®
Calibration
C2 Electronic Calibration enables a scale system to be calibrated electronically without
using certified test weights. A C2 weighing system consists of up to eight load sensors, a
junction box, interconnect cable and an instrument with C2 capabilities, such as the HI
4050 Weight Controller. Digital information within every Hardy Process Solutions C2-
certified load sensor details its unique performance characteristics. The HI 4050 Weight
Controller reads the performance characteristics of each load sensor and detects the
