Functional
Ground
The sensor cable must be shielded. The shield must:
• extend the length of the cable, but be connected only at the 1771 I/O chassis
• extend up to the point of termination
Important: The shield should extend to the termination point, exposing just enough cable to
adequately terminate the inner conductors. Use heat shrink or another suitable
insulation where the wire exits the cable jacket.
RTD Input Module 5
Publication 1771Ć5.63 - November 1998
Connect your I/O devices to the field wiring arm (cat. no. 1771-WF)
shipped with the module.
!
ATTENTION: Remove power from the 1771 I/O
chassis backplane and field wiring arm before
removing or installing an I/O module.
•
Failure to remove power from the backplane or
wiring arm could cause module damage, degradation
of performance, or injury.
•
Failure to remove power from the backplane could
cause injury or equipment damage due to possible
unexpected operation.
