Connection Guidelines
•
Always connect analog signals using shielded, twisted pair cables. Unshielded cables
may lead to values outside the specified tolerance limits in environments subject to heavy
noise.
•
Connect the cable shield to functional earth ground immediately after the cables enter the
control cabinet.
•
Connect the cable shield to a shield bus if you are not using a closed control cabinet.
•
NI recommends using the NI Remote I/O Shield Set for optimal shield connection.
•
Make sure that devices you connect to the REM-11102 are compatible with the module
specifications.
•
Push the wire into the terminal when using a solid wire or a stranded wire with a ferrule.
•
Open the terminal by pressing a screwdriver into the spring lever when using a stranded
wire without a ferrule.
