Heavy-Duty Signal Trimming with Built-In Surge Protection

Built for the most demanding outdoor environments, the JB8SPT TuffSeal® junction box offers advanced signal trimming and surge protection for truck, livestock, and railroad scale systems. It features a durable NEMA Type 4X-rated enclosure, removable connectors for easy field maintenance, and a conformal coated circuit board to prevent moisture and debris damage.

Designed for even-numbered load cell configurations (2, 4, 6, or 8 cells), this rugged junction box provides both individual and section trimming. Integrated transient protection safeguards your load cell system against unexpected power surges, while the PreVent™ breather vent equalizes internal pressure to avoid condensation buildup.

Key Features

  • Transient Surge Protection
    Built-in board protects internal electronics from damaging voltage spikes.

  • PreVent™ Breather Vent
    Minimizes internal condensation, ideal for outdoor applications.

  • Individual and Section Trimming
    Fine-tune load cell output easily with precision potentiometers.

  • Removable Connectors
    Pluggable screw-type terminals make installation and replacement quick and clean.

  • Expansion-Ready Design
    Features an integrated expansion port for system growth or integration.

Applications

  • Truck Scales

  • Livestock Scales

  • Railroad Track Scales
