Description

3.1

The SIWAREX JB junction box is used in weighing systems with extra-low voltages ≤ 30 V. The

SIWAREX JB junction box is used to connect load cells to the electronic weighing system.

You can connect up to four load cells in parallel in a junction box.

Figure 3-1

If you have more than four load cells, connect an additional SIWAREX JB junction box in parallel

using a cross-connection. The extension set is required for this, see Accessories (Page 39). The

cross-connection allows you to connect up to three load cells in the first junction box. Up to four

load cells can be connected in the second junction box.

Load cells with 4-wire and 6-wire strain gauges can be connected.

The cable connection from the junction box to the electronic weighing system and between two

junction boxes is implemented with a six-wire system.
