The Rice Lake JB4SS TuffSeal® Signal Trim Junction Box is a heavy-duty industrial junction box designed to combine and balance signals from multiple load cells in demanding weighing environments. Engineered with a rugged stainless steel NEMA Type 4X enclosure, the JB4SS provides superior protection against moisture, dust, corrosion, and washdown conditions, making it ideal for industrial, agricultural, and process weighing applications.
Designed to accommodate two, three, or four single load cells, the JB4SS features individual signal trimming capabilities that allow technicians to precisely balance load cell outputs for improved weighing accuracy and scale performance. Integrated jumpers make it easy to enable or disable individual load cells during troubleshooting, maintenance, or system configuration.
The junction box includes Rice Lake's PreVent™ breather vent technology, which helps equalize pressure and reduce condensation caused by temperature fluctuations. Combined with a conformal-coated circuit board, the internal electronics are protected from moisture and contaminants, ensuring long-term reliability in harsh environments.
An integrated expansion port allows additional junction boxes to be connected when larger multi-load-cell systems are required. This flexibility makes the JB4SS an excellent solution for floor scales, tank weighing systems, hopper scales, vessel weighing applications, and other industrial weighing installations requiring dependable signal summing and trimming.
Built with spring-clamp screwless terminals that accept 12-28 AWG wiring, the JB4SS simplifies installation while providing secure electrical connections. Its proven design, durable construction, and advanced load cell management features make it a trusted choice for industrial weighing professionals worldwide.
