Eight-Channel Surge-Protected Weighing Junction Box

Product Showcase Content
Product Name Eight-Channel Surge-Protected Weighing Junction Box
Product Image eight-channel surge-protected load cell junction box

Reference configuration shown. The supplied enclosure and components are subject to the approved specification.

Product Overview This junction box brings multiple analog load cells together and sends their combined signal to a weighing indicator through one homerun cable. An eight-channel layout suits larger livestock scales, vehicle weighing platforms and other multi-point systems. Transient protection helps reduce the risk of electrical surge damage when the box is correctly grounded and installed.
Key Features
  • Connections for up to eight load cells, subject to the selected wiring configuration.
  • Individual load cell and section signal trimming for scale commissioning.
  • Surge-protection components for exposed weighing installations.
  • Organized terminals and cable entries for installation and service access.
  • Protective enclosure options for humid, dusty or washdown-prone farm locations.
Structural Components The typical assembly comprises an enclosure and sealed cover, an eight-channel summing board, load cell terminals, signal-trim controls, transient-protection components, a grounding point, and cable glands for load cell and indicator cables. Final component selection is confirmed against the project wiring diagram.
Working Principle Each load cell feeds its analog signal into the summing board. During calibration, a technician can adjust individual or section outputs to balance the scale. The combined signal then travels to the indicator. The transient-protection circuit provides an additional path for electrical disturbances when the complete weighing system has been grounded correctly.
Technical Specifications
  • Input channels: Up to eight load cells.
  • Trimming: Individual and section signal trim, according to configuration.
  • Protection: Transient-protection arrangement; details available upon request.
  • Enclosure material and environmental rating: Available upon request.
  • Cable entries, dimensions and indicator compatibility: According to project requirements.
Applications Suitable for multi-load-cell cattle and pig weighing platforms, livestock handling scales, farm vehicle scales, and weighing equipment integrated into steel structure livestock buildings. Installation requirements should be reviewed against local climate, cleaning practices and the scale layout.
Customization Options Enclosure material, cable-gland arrangement, terminal layout, grounding arrangement and indicator connection can be specified according to project requirements. Share the load cell model, number of weighing points, cable sizes and installation environment when requesting a configuration.
Installation & Maintenance Mount the box where technicians can reach it and where standing water cannot collect. Route load cell and homerun cables through correctly sized glands, follow the approved wiring diagram, and verify the protective earth connection before commissioning. Keep the cover sealed in service; inspect cable entries, terminals, seals and surge-protection components during scheduled scale maintenance.
Product FAQ

Can it be used for a pig farm scale?
Yes, if the selected box matches the scale's load cells, indicator, cable arrangement and site conditions.

Does surge protection replace grounding?
No. Correct grounding is essential to the operation of the protection circuit.

Is calibration still required?
Yes. Signal trimming and full scale calibration should be completed after installation.
