Module Overview
This chapter describes the following topics:
•General description
•Input specifications
•Data formats
•Hardware features
•System overview
The Micro800™2085-IR8-SC is an isolated. 8-channel RTD/Resistance module
designed to expand the local I/O capability of Rockwell Automation Micro850
and Micro870 Systems over its Expansion I/O buses. The minimum system
requirement in which an Expansion I/O Module can be installed is a Micro850 or
Micro870 Controller and a controller power supply.
The number of 2085-IR8-SC modules that can be installed with a Micro850/870
PLC is based on the current controller firmware revision and CCW software
revision.
Section 1.1
General
Description

1-2 Chapter 1: Module Overview
User's Manual Pub. 0300321-01 Rev. A
The module provides up to eight, concurrent channels of 2-, 3-, or 4-wire RTD
and resistance measurements. It provides RTD types Pt 385, Pt 3916, Cu 426, Ni
618, Ni 672, Ni-Fe 518, and direct ohm (0-150, 0-500, 0-1000, 0-3000)
measurements.
The module provides:
•8 input channels of RTD and resistance measurements.
•Four data formats.
•Range scaling of input data.
•Four filter frequencies.
•Units in Degrees Centigrade and Fahrenheit.
•Channel bias adjustment.
•Alarm notification on each channel status:
-Over or under range detection (from user-defined values).
-Process alarm and latching.
-Open wire detection.
-ADC communication fault.
All inputs have fault tolerance and ESD protection to avoid damage to circuitry
on the board. The modules use 50 VAC working Reinforced Insulation between
the inputs and the backplane.
The 2085-IR8-SC module uses a 20-bit Sigma-Delta analog-to-digital converter
to achieve 16-bit resolution.
Each input channel is individually configurable via Rockwell-provided
Connected Component Workbench (CCW) software for the Micro850 and
Micro870 family controllers or with the Module Configuration Converter (MCC)
utility from Spectrum Controls, Inc.
The module is factory calibrated and tested before shipping. After installation,
the modules begin operation in a default, usable condition without user
parameters first being set up or defined. During power startup, all inputs are
disabled and off until a valid configuration has been received. The default
configuration is for all channels enabled in the 3-wire, 100PT385 range with the
17 Hz filter in Engineering ×1 units.

1.4.1 LED Blink Codes
A 2085-IR8-SC module uses a single, green OK LED to show power or module
operational status.
When startup is completed, and all internal tests have passed, the LED is solid
GREEN. If the LED remains off, there is an error with the module: it may not
have power, or the module failed to pass the self-test.

Compliance to
European
Union Directives This product is approved for installation within the European Union and EEA
regions. It has been designed and tested to meet the following directives.
2.1.1 EMC Directive
The 2085-IR8-SC is tested to meet Council Directive 2014/30/EU
Electromagnetic Compatibility (EMC) and the following standards, in whole or
in part, documented in a technical construction file:
•IEC 61000-6-4 Electromagnetic compatibility (EMC)–Part 6-4: Generic
standards–Emission standard for industrial environments
•IEC 61000-6-2 Electromagnetic compatibility (EMC)–Part 6-2: Generic
standards–Immunity for industrial environments
•EN 61131-2 Programable controllers - Part 2: Equipment requirements
and tests
Section 2.2
Power
Requirements
WARNING
The backplane power and the analog inputs of the device shall only be
supplied by an Isolated Secondary Limited Energy Low Voltage source.
The module receives power through the bus interface from the +5 VDC/+24
VDC system power supply, and a 24 VDC field power supply. Both must be
present for the module to operate.
Current rating at + 5 V is 94 mA maximum; for +24 V it is 15 mA maximum.

General
Considerations The 2085-IR8-SC module is suitable for use in an industrial environment when
installed in accordance with these instructions. Specifically, this equipment is
intended for use in clean, dry environments Pollution degree 2
2
.
2.3.1 Hazardous Location Considerations
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D or
non-hazardous locations only. The following WARNING statement applies to
use in hazardous locations.
WARNING
EXPLOSION HAZARD
•Substitution of components may impair suitability for Class I,
Division 2; Class II, Division 2; and Class III, Division 2. Do not
replace components or disconnect equipment unless power has
been switched off or the area is known to be non-hazardous.
•Do not connect or disconnect components unless power has been
switched off or the area is known to be non-hazardous.
•This product must be installed in an enclosure.
•All wiring must comply with N.E.C. article 501-4(b), 502-4(b), or
503-3(b), as appropriate for Class I, Class II, and Class III
equipment.
2.3.2 Prevent Electrostatic Discharge
WARNING
Electrostatic discharge can damage integrated circuits or semiconductors if
you touch I/O expansion port connector pins or the terminal block on the
module. Follow these guidelines when you handle the module:
•Touch a grounded object to discharge static potential.
•Wear an approved wrist-strap grounding device.
•Do not touch the port connector or connector pins.
•Do not touch circuit components inside the module.
•If available, use a static-safe work station.
•When it is not in use, keep the module in its static-shield bag.
2
Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally
a temporary conductivity caused by condensation is expected.

2.3.3 Remove Power
WARNING
Remove power before removing or inserting this module. When you
remove or insert a module with power applied, an electrical arc may occur.
An electrical arc can cause personal injury or property damage by:
•Sending an erroneous signal to your system’s field devices,
causing unintended machine motion.
•Causing an explosion in a hazardous environment.
•Causing an electrical arc. Electrical arcing causes excessive wear
to contacts on both the module and its mating connector and may
lead to premature failure.
2.3.4 Selecting a Location
Reducing Noise
Most applications require installation in an industrial enclosure to reduce the
effects of electrical interference. Analog channels are highly susceptible to
electrical noise. Electrical noise coupled to the analog channels will reduce the
performance (accuracy) of the module. Group your modules to minimize adverse
effects from radiated electrical noise and heat. Consider the following conditions
when selecting a location for the analog module. Position the module:
•Away from sources of electrical noise such as hard-contact switches,
relays, and AC motor drives.
•Away from modules which generate significant radiated heat. Refer to
the module’s heat dissipation specification.
In addition, route shielded, twisted-pair analog input wiring away from any high
voltage I/O wiring.
Section 2.4
Mounting
WARNING
Keeping module free of debris and avoiding overheating:
•Do not remove protective debris strip until after the module and
all other equipment near the module is mounted and the wiring is
complete.
•Once wiring is complete, and the module is free of debris,
carefully remove protective strip.
•Failure to remove strip before operating can cause overheating.

You can choose to wire the expansion I/O module before installing it next to the
controller or wire it once the module is secured in place.
Place the module next to the controller against the panel where you are mounting
it. Make sure the controller and module are spaced properly.
