Rice Lake 680 Synergy Series Digital Weight Indicator IP69K Stainless Steel

The Rice Lake 680 Synergy Series Digital Weight Indicator is a versatile industrial weighing indicator designed to deliver reliable performance, advanced communication capabilities, and straightforward automation for a wide range of weighing applications. Combining the power of sophisticated instrumentation with the ease of operation of a traditional weight indicator, the 680 Synergy Series is ideal for manufacturing facilities, food processing plants, warehouses, agricultural operations, shipping departments, and industrial process control environments.

Built for real-world industrial conditions, the 680 features a rugged AISI 304 stainless steel enclosure with an IP69K environmental rating, providing outstanding protection against dust, moisture, and high-pressure washdowns. This makes it particularly well-suited for harsh industrial and sanitary environments where equipment durability and reliability are critical. When equipped with the optional RJ45 Ethernet connector, the enclosure maintains an IP66 rating when the protective cover is in place.

The indicator utilizes a bright LED display with seven large 0.8-inch digits and eight annunciators, providing excellent visibility in industrial environments. A full numeric keypad allows operators to quickly enter tare values, setpoints, and operational parameters while simplifying weighing tasks and system configuration. The battery-backed clock and calendar ensure that time and date information are maintained even during power interruptions.

Designed for general-purpose weighing and basic automation, the 680 includes a configurable batch engine capable of performing batching and filling operations. With up to 20 configurable setpoints and four onboard digital I/O points, users can automate multi-step weighing processes, material dispensing, filling operations, and production workflows. The indicator also supports customizable ticket printing with formattable gross, net, setpoint, and auxiliary print formats, making it ideal for production reporting and transaction documentation.

The 680 Synergy Series offers extensive communication capabilities, including dual RS-232 ports, RS-485/422 communication, Micro USB connectivity, and Ethernet TCP/IP networking. These interfaces allow seamless integration with printers, PCs, PLCs, data collection systems, and industrial automation equipment. Optional analog output cards provide 0–10 VDC, 0–20 mA, or 4–20 mA signals for process control and monitoring applications.

With an internal resolution of up to 8,000,000 counts and display resolution up to 1,000,000 divisions, the 680 delivers precise and repeatable weighing performance. The indicator supports up to eight 350-ohm load cells or sixteen 700-ohm load cells, making it suitable for floor scales, tank scales, hopper scales, platform scales, batching systems, and other industrial weighing applications.

Certified for legal-for-trade applications, the 680 Synergy Series carries NTEP, Measurement Canada, OIML, CE, UKCA, cULus, IEC, and NMI approvals, ensuring compliance with international weighing standards and regulations.

Whether used for production weighing, batching, filling, inventory management, shipping operations, or industrial process control, the Rice Lake 680 Synergy Series provides dependable weighing performance, modern connectivity, and durable construction for demanding industrial environments.
