Rice Lake JB8SPT TuffSeal Signal Trim Junction Box - Manual (Page 5)

Introduction 1
1.0 Introduction
Figure 1-1. TuffSeal Truck Scale Version Junction Box
The TuffSeal ® eight-channel junction box is a signal trim junction box that can accommodate up to eight load
cells and is used in truck scale installations. Additional load cells can be connected to the junction box by wiring
additional junction boxes to the expansion terminal located on the main board. Both models have a new Prevent
®
breather vent. The breather vent inhibits the buildup of pressure caused by sudden temperature or environmental
changes and should be changed every six months to one year as it will become dirty over time. When correctly
installed, both models can withstand 900 PSI water pressure.
Both models will function properly without modification. However, load cell output can be individually trimmed
with potentiometers which is further explained in Section 5.0 on page 7 of this manual.
Transient protection comes standard with the JB8SPT model junction box.
