Installation and Wiring

For example, for Belden 8761 two conductor, shielded cable and a 1769-IF4
input module:

Rc = 16

Ω

/1000 ft

Rs = 15

Ω

Ri = 220 K

Ω

As output impedance (Rs) and/or resistance (dc) of the cable (Rc) get larger,
system accuracy decreases. If you determine that the inaccuracy error is
significant, implementing the following equation in the control program can
compensate for the added inaccuracy error due to the impedance of the output
module and cable.

In a current loop system, source and cable impedance do
not impact system accuracy.
