The Rice Lake EL504 Signal Trim Junction Box is a rugged industrial-grade load cell summing and trimming solution designed for truck scales, floor scales, and other weighing systems requiring accurate signal balancing. Built with a durable stainless steel NEMA Type 4X enclosure, the EL504 protects sensitive electronics from moisture, dust, corrosion, and washdown conditions commonly found in industrial environments.
Designed to connect two or four single load cells, the EL504 provides individual signal trimming for each load cell, allowing technicians to precisely balance outputs and improve overall scale accuracy. This signal-trimming capability helps ensure consistent weight readings across the entire weighing platform. The EL504 is intended for systems using an even number of load cells, and any unused channels require modification before use.
Installation and maintenance are simplified through removable two-piece connectors that allow quick wiring and servicing. The junction box also includes five nylon strain-relief cable fittings that help protect wiring connections from movement, vibration, and environmental exposure.
The internal circuit board features an anti-fungal protective coating to enhance reliability in humid or demanding operating conditions. Combined with precision 25-turn cermet potentiometers, the EL504 delivers dependable long-term performance for industrial weighing applications.
Its compact footprint makes the EL504 particularly suitable for installations where space is limited while still providing the performance and durability expected from Rice Lake weighing equipment.
