Munters RJB-4 (RJB-4) enables connecting up to 16 load cells to a single RSW-2 Controller or a Platinum
Controller. This document details the wiring procedures between the scales and the RJB-4, and between
the RJB-4 and the RSW-2.

The RJB-4 comes with:

• AWG 14 (thick) cable used to ground the silo (Figure 5)

• AWG 22 (thin) cable for wiring the RJB-4 to a grounding rod (Figure 6)

1.1 Connecting Silo Load Cells to the RJB-4

Described below are the wiring connections between the load cells to the RJB-4 Junction Box, and from
the junction box to the Silo Weighing Controller (RSW-2).

Load cell part numbers:

• RSLC-04: 911-03-XXXXX

• RSLC-10: 911-04-XXXXX

• RSLC-25: 911-05-XXXXX

NOTE: The RSLC supports RSW-2 boards, version 7.0 and above.

1. Each load cell has a 4-wire shielded cable.

o

Connect each load cell to the RJB-4 double connector with exactly the colors that written

on the RJB-4 PCB board.

2. Repeat for each load cell.

NOTE: The RJB-4 can support more than one load cell on each terminal. To connect more than four

load cells to the RJB-4, place a second set of load cell wires into each terminal load cell block.

Figure 2 illustrates four load cells connected to the RJB-4.

3. The RSW-2 cell has a 4-wire shielded cable. Run these wires from the RSW-2 Silo A
terminal block to the RJB-4 controller terminal block; attach each wire to the input slot with
same color. For example, connect the red wire to the red input slot. Figure 3 illustrates the
wiring.
