Which one is this? The 4-20 mA add-on for a scale you already own (HSCo or most other makes), fitted and configured to your system. Want a new scale with the 4-20 mA built in? See the 4-20 type Customized Scale.
4-20 mA weighing scale output: questions buyers ask
A 4-20 mA weighing scale output carries the weight as an analog current signal to a compatible PLC input. 4 mA is the low end and 20 mA the high end; HSCo sets which weights those two points represent. The output can be fitted to platform scales, tank weighing systems, hopper scales and custom builds for chemical processing, batching and food manufacturing.
4-20 mA carries the weight as a continuous analog current for a compatible input. RS485 carries digital data and can connect several scales on one line; the protocol decides which readings and status fields are sent. Tell us what your controller accepts. We build an analog output, an RS485 connection or both to match it.
Whichever weights your process needs; there is no fixed HSCo span. Tell us the lowest and highest weights to represent, whether the loop is powered by the PLC or by the scale, and the input resistance. We set the output to match your controller and your weighing range.
Platform scales, tank weighing systems, hopper scales and custom builds, and the 4-20 mA Output Customised Scale built for PLC-controlled lines in chemical processing, batching plants and food manufacturing. HSCo can build a relay output alongside it, so the PLC reads the weight and the scale switches a valve at your set point. Any HSCo scale can be built with it.
