2–7 RTD Input Wiring
The RTD connections are shown in figure
2.6, with the compensating lead connected to
terminal 12. For two-wire RTD inputs, terminals
12 and 13 should be linked. A three-wire RTD
offers the capability of lead resistance compen-
sation, provided that the three leads are the same
gauge and equal in length.
For the purpose of accuracy, two-wire RTD
should be avoided, if possible. A 0.4 ohm lead
resistance in a two-wire RTD will produce 1°C
temperature error.
2–8 Linear DC Input Wiring
DC linear voltage and linear current connections for input 1 are shown in
figure 2.7 and figure 2.8.
DC linear voltage and linear current connections for input 2 are shown in
figure 2.9 and figure 2.10.
