iQUBE³ Digital Diagnostic Junction Box
- Designed for weighing systems using the 1280 Enterprise™ Series indicator
- iQUBE³ CPU board: Four A/D channels, SD Slot, RS232/485, four DIOs, Ethernet TCP/IP (wired), USB-C
- iQUBE³ CPU board supports networking up to five iQUBE³ four-channel boards (four A/D channels each), for a total of 24 A/D channels; connection can be up to four separate scales and a system total
- Diagnostic routines for weighing errors and system health
- Additional diagnostics for overloaded, underloaded, zero reference, drift, noise and unbalanced conditions
- Onboard status LEDs for communication and visual bi-color indication of load cell health
- Load cell emulator compensates for a failed load cell
- Cal-Match® algorithm automatically trims and calibrates the scale in one pass of test weights (stopping over each load cell)
- Two option slots available

Improve Your System with a Digital Diagnostic Junction Box
The iQUBE³ junction box provides stable weight readings for any analog load cell through its reliable digital signal. Built-in reporting for load cell status, voltages and error conditions can expedite troubleshooting to maximize system uptime.
Simplified Installation and Use
The iQUBE³ digital diagnostic junction box has an easier and faster setup compared to a traditional analog junction box. Because each load cell is individually monitored, there is immediate visibility for issues including drift, instability or a failing load cell, limiting troubleshooting time. You also gain cleaner digital signal transmission, better noise immunity and simple plug-and-play configuration, making routine scale maintenance quicker and more accurate.
