Relay Output Weighing Scale – Switch Machines On or Off at a Set Weight
Price on Request
HSCo weighing scale with relay outputs built in: stops filling, starts sealers, opens valves or sounds alarms at set weights. Table-top or MS / SS platform.
A relay output scale is an HSCo weighing scale with relay outputs built in at the factory, so it can switch other equipment on or off at a set weight. It can stop a filling pump at the target weight, start a sealing machine, open a valve or sound an alarm, cutting manual work and giving the same result every time. We build it on a table-top scale or an MS or SS platform scale.
What it can control
- Filling and dispensing: cut off filling automatically when the target weight is reached.
- Packaging lines: trigger sealing or labelling machines at a weight threshold.
- Check weighing: sound a buzzer or work a reject mechanism for wrong weights.
- Batch mixing: control material addition or discharge during batching.
- Safety: sound an alarm when weight goes beyond a safe limit.

Scale or add-on?
This product is a complete scale with relay outputs built in. Already have a scale? The relay output for weighing scales is the add-on that fits an existing HSCo scale and most other makes.
Questions buyers ask
It switches an external device on or off when the weight reaches a value you set.
Yes. That is one of its most common uses.
Table-top and MS or SS platform scales.
Yes, with our relay output add-on.
Watch relay output scale weight-limit settings
Is there a video showing how to set weight limits on a relay output scale?
Yes. The relay scale weight-limit programming demo sets a lower and an upper weight limit, then shows how the outputs and the buzzer respond when the weight is below, within or above that range.
