JB104SS 4-Channel Stainless Steel Junction Box
4 Channel Summing
Model JB104SS junction box is designed to connect and trim up to four load cells per board. It may also be used in combination with additional junction boxes through the use of the expansion port on the main board to connect multiple junction boxes. This will allow the summing of more than four load cells if needed. In its most basic form, this junction box provides a convenient method for wiring multiple load cells to a single indicator. Junction boxes are commonly used in weighing applications where a tank or scale is supported by more than one load cell. The individual load cell cables are wired into the junction box and then a single cable connects the junction box to the instrumentation.
The JB104SS is a small 4×6.5×1.75 inch stainless steel NEMA 4 rated box suitable for installations where space is limited. Standard configuration is for 2 to 4 load cells and provides a 20% trim range. Spring clips are used for the load cell connections.

Wiring the Junction Box
The JB104SS junction box model has been designed to connect and trim up to four load cells per board. However it is possible to use this box with other combinations. Use the expansion port on the main board (shown below), to connect multiple junction boxes in series to accommodate applications that have more than four load cells.
Expansion Port Location
wires to the terminals, strip the wire insulation back 1/4″ to expose the wire. The spring-loaded terminals will accommodate 12 to 28 gauge wire. To connect the load cell wires to the appropriate connectors, push in the quick-connect lever with a small screwdriver. While holding in the lever, insert the appropriate wire into the exposed wire opening. Release the screwdriver to allow the spring-loaded gate to close and lock the wire in place.
The indicator terminal strip is used to connect the main cable to the indicator. Determine the indicator’s load cell input connections from the operating manual. Run a cable from your indicator terminal into the junction box through the larger cord grip and make the connections on the indicator terminal using the same procedure as inserting load cell cables to the appropriate connectors.
