The photo below shows the proper connectivity for a 4-20 mA signal. To reduce ambient noise, a
properly shielded cable should be used. A 50 ohm precision resistor must be placed across the +
and – terminals in parallel with the input signal wires. Also, a jumper must be made between the –
and Cterminals (refer to Figure 2-7 in Chapter 2).
