2Micro800™ Non-isolated Thermocouple Plug-in Module
Publication 2080-WD006A-EN-P - September 2011
Environment and Enclosure
Preventing Electrostatic Discharge
ATTENTION
This equipment is intended for use in a Pollution Degree 2 industrial
environment, in overvoltage Category II applications (as defined in IEC
60664-1), at altitudes up to 2000 m (6562 ft) without derating. This equipment
is considered Group 1, Class A industrial equipment according to IEC/CISPR
11. Without appropriate precautions, there may be difficulties with
electromagnetic compatibility in residential and other environments due to
conducted and radiated disturbances.
This equipment is supplied as open-type equipment. It must be mounted
within an enclosure that is suitably designed for those specific environmental
conditions that will be present and appropriately designed to prevent personal
injury resulting from accessibility to live parts. The enclosure must have
suitable flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5V A, V2, V1, V0 (or equivalent) if
non-metallic. The interior of the enclosure must be accessible only by the use
of a tool. Subsequent sections of this publication may contain additional
information regarding specific enclosure type ratings that are required to
comply with certain product safety certifications.
In addition to this publication, see:
• Industrial Automation Wiring and Grounding Guidelines, Rockwell
Automation publication 1770-4.1, for additional installation
requirements.
• NEMA Standard 250 and IEC 60529, as applicable, for explanations of
the degrees of protection provided by different types of enclosure.
ATTENTION
This equipment is sensitive to electrostatic discharge, which can cause
internal damage and affect normal operation. Follow these guidelines when
you handle this equipment:
• Touch a grounded object to discharge potential static.
• Wear an approved grounding wriststrap.
• Do not touch connectors or pins on component boards.
• Do not touch circuit components inside the equipment.
• Use a static-safe workstation, if available.
• Store the equipment in appropriate static-safe packaging when not in
use.

North American Hazardous Location Approval
The following modules are North American Hazardous Location approved:
2080-TC2
The following information applies
when operating this equipment in
hazardous locations:
Informations sur l’utilisation de cet
équipement en environnements dangereux:
Products marked "CL I, DIV 2, GP A, B, C, D" are
suitable for use in Class I Division 2 Groups A,
B, C, D, Hazardous Locations and nonhazardous
locations only. Each product is supplied with
markings on the rating nameplate indicating the
hazardous location temperature code. When
combining products within a system, the most
adverse temperature code (lowest "T" number)
may be used to help determine the overall
temperature code of the system. Combinations
of equipment in your system are subject to
investigation by the local Authority Having
Jurisdiction at the time of installation.
Les produits marqués "CL I, DIV 2, GP A, B, C, D" ne
conviennent qu'à une utilisation en environnements de
Classe I Division 2 Groupes A, B, C, D dangereux et non
dangereux. Chaque produit est livré avec des marquages
sur sa plaque d'identification qui indiquent le code de
température pour les environnements dangereux.
Lorsque plusieurs produits sont combinés dans un
système, le code de température le plus défavorable
(code de température le plus faible) peut être utilisé
pour déterminer le code de température global du
système. Les combinaisons d'équipements dans le
système sont sujettes à inspection par les autorités
locales qualifiées au moment de l'installation.

Publication 2080-WD006A-EN-P - September 2011
Parts List
Your package contains one Micro800 Non-isolated Thermocouple plug-in
module, two module fastening screws, one trimmed/formed bendable lead
NTC thermistor and these pin out guide wiring instructions.
You can choose to wire the plug-in before inserting it onto the controller, or
wire it once the module is secured in place.
ATTENTION
• This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR 11. Without appropriate precautions, there may be
difficulties with electromagnetic compatibility in residential and other
environments due to conducted and radiated disturbance.
• Be careful when stripping wires. Wire fragments that fall into the controller
could cause damage. Once wiring is complete, make sure the controller is
free of all metal fragments.
• Do not wire more than 2 conductors on any single terminal.
• If you insert or remove the plug-in module while power is on, an electrical
arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous
before proceeding.
• Use shielded twisted core cables to connect the sensor.
• The shield should be grounded only at controller end.
• Connect the thermocouples directly to the module.
• Do not insert or remove the plug-in module while power is applied,
otherwise, permanent damage to equipment may occur.

Wire the CJC Thermistor
2080-TC2 CJC Thermistor Wiring and Mounting Guide
The position for the thermistor, as illustrated, helps to compensate for
thermoelectric voltages developed at screw junction equally for
thermocouples connected to channels 0 and 1. If the bead is not in proper
contact with the screw, there will be deviation in readings due to inadequate
isothermal compensation.
This sensor is passive, non-polarized and readily available in the market.
Wire the Module in the Field
Connect the thermocouple sensors directly to the module terminals. If a
separate cable is used to connect the thermocouple to the module, the CJC
thermistor has to be mounted to the cable at thermocouple junction only.
