Extension cable (W03-2168-000)
W03-2168-000 IS barrier to BW RigRat cable, 100meters, with 3-pin connector.
Total 100m cable IS parameters: (C=80pF/m; L=0.7uH/m; R=23.2mΩ/m)
Ct=8nF
Lt=0.07mH

BW RigRat IS parameters in hazardous area:
Ui=24V
Ii= 150 mA
Pi=1.15W
Ci=0.36nF.
Li=0uH

For hazardous applications, these conditions must be met:
Uo ≤ Ui
Io ≤ Ii
Po ≤ Pi
Co ≥ Ci + Ct
Lo ≥ Li + Lt
Uo/Io/Po/Co/Lo are IS barrier output parameters
Ui/Ii/Pi/Ci/Li are RigRat input parameters
Ct/Lt are extension cable additional parameters
