Frequently Asked Questions

What does the A&D HVW-04C Comparator Relay Output/Buzzer do?

The A&D HVW-04C adds comparator relay output, an audible buzzer, and contact input functionality to compatible A&D platform scales. It allows checkweighing results to trigger external equipment or audible alerts, making it useful for production, sorting, filling, packaging, and quality-control applications.

What comparator relay outputs are available on the A&D HVW-04C?

The HVW-04C provides five comparator relay outputs: HIHI, HI, OK, LO, and LOLO, plus a common terminal. These outputs can communicate different checkweighing results to compatible external equipment such as signal lights or control systems. When three-level comparator mode is selected, the interface uses the HIHI, OK, and LOLO outputs.

How does the buzzer function work on the HVW-04C?

The HVW-04C has a buzzer built into its circuit board that can sound according to the scale's comparator results. Users can configure which comparison conditions activate the audible alert. A&D specifies an approximate sound pressure level of 58 dB at 1 meter from the display unit, making the feature useful when operators need an audible indication in addition to the scale's LED comparator lights.

What are the electrical ratings of the HVW-04C relay outputs?

A&D specifies the HVW-04C solid-state relay outputs for a maximum of 50 V DC and 100 mA DC, with a maximum ON resistance of 8 Ω. These ratings should be followed when integrating the interface with external control equipment, indicators, or other compatible devices.

Can the HVW-04C be used with USB or RS-232C interfaces on the same scale?

Yes. A&D's HV/HW-C/CP platform supports separate optional interfaces. The HVW-04C handles comparator relay output, buzzer, and contact input, while the HVW-02CB provides USB communication and the HVW-03C provides RS-232C. A&D documentation shows the HVW-04C can be installed alongside optional data-communication interfaces in supported configurations.
