Description:
Inputs on analog controllers employ digital high-frequency filters that significantly reduce the
effects of electrical noise on input signals. However, because of the variety of applications and
environments where analog controllers are installed and operated, it is impossible to ensure
that all environmental noise will be removed by the input filters.
Several specific steps can be taken to help reduce the effects of environmental noise on
analog signals:
• install the MicroLogix 1000 system in a properly rated (i.e., NEMA) enclosure. Make
sure that the MicroLogix 1000 system is properly grounded.
• use Belden cable #8761 for wiring the analog channels, making sure that the drain
wire and foil shield are properly earth grounded.
• route the Belden cable separate from any ac wiring. Additional noise immunity can be
obtained by routing the cables in grounded conduit.
Grounding Your Analog Cable
Use shielded communication
cable (Belden #8761). The Belden
cable has two signal wires (black
and clear), one drain wire, and a
foil shield. The drain wire and foil
shield must be grounded at one
end of the cable. Do not ground
the drain wire and foil shield at
both ends of the cable.
Explosion Hazard:
• Substitution of components may impair suitability for Class I,
Division 2.
• Do not replace components or disconnect equipment unless
power has been switched off and the area is known to be
non-hazardous.
• Do not connect or disconnect connectors while circuit is live
unless area is known to be non-hazardous.
• This product must be installed in an enclosure. All cables
connected to the product must remain in the enclosure or be
protected by conduit or other means.
• The interior of the enclosure must be accessible only by the use
of a tool.
• For applicable equipment (for example, relay modules), exposure
to some chemicals may degrade the sealing properties of the
materials used in these devices:
– Relays, epoxy
It is recommended that you periodically inspect these devices for
any degradation of properties and replace the module if
degradation is found.
