iQUBE²® Digital Diagnostic Junction Box
As of: Thursday, September 17, 2026
Standard Features
iQUBE2 board has four A/D channels
Supports networking up to four boards with a total of 16 A/D channels; connection can be up to four separate platforms with a system total or four separate scale systems
Diagnostic routines for weighing errors and system health
Tests for overloaded, underloaded, zero reference, drift, noise and unbalanced conditions
Onboard status LEDs for communication and visual bi-color indication of cell health
Load cell emulation compensates for load cell failure until a repair can be made
Cal-Match® algorithm automatically trims and calibrates the scale in one pass of test weights (stopping over each mount)
Standard communications
Option card slot for fiber-optic, Ethernet TCP/IP, wireless Ethernet TCP/IP, USB or RS-232/RS-485
Communicates to 920i® Series, 1280 Enterprise™ Series and VIRTUi2® using ASCII (EDP) serial commands
Applications
Truck, railroad, tank and hopper scales
Multi-channel scales
Identify Problems Before They Happen
Rice Lake Weighing Systems’ iQUBE2® digital diagnostic junction box compares the output of each load cell to adjacent load cells, ensuring optimal performance and warning operators of weight irregularities. iQUBE2 converts any analog load cell system into a modern digital system, without replacing individual load cells.
Enhance the Performance of Any Scale System
iQUBE2 is ideal for systems using single or multiple scales with two or more load cells. Floor scales, hopper scales, tank scales, vehicle scales and dosing systems can all benefit from an upgrade to the iQUBE2 digital diagnostic junction box system.
With accelerated data transfer, batching and dosing applications can efficiently achieve target weights when speed and accuracy are critical.
Instant Alerts and Cell Emulation
Diagnostics can be viewed on the user interface and an email alert is sent in the event of a component error. If a load cell fails, the cell emulation feature calculates weight based on known comparisons to functional load cells, keeping your scale functional until the load cell can be replaced.
