1.2.1 Status Display
The Status Display will be illuminated with a “0” when the module is functioning normally. If
the Status Display is not lit, or if it displaying something other than “0”, refer to Chapter 3 for
troubleshooting.
1.2.2 I/O Wiring Connector
The 2500C-8-AI module using the standard 2500C-32F Field Wiring Connector. This
connector provides 32 connections and accepts 14-22 AWG wires.
1.3
Asynchronous Operation
The module operates asynchronously with respect to the PLC (a scan of the PLC and input
sampling of the module do not occur at the same time). Instead, the module will translate all
analog inputs in one module update (3.5 milliseconds maximum) and store the translated
words in buffer memory. The PLC retrieves the stored words from the module buffer
memory at the start of the I/O scan.
1.4
Modes of Operation
The 2500C-8-AI supports two major modes of operation: Classic mode and Classic Plus
mode.
1.4.1 Classic Mode
In Classic mode (or Low Density) operation, the 2500-8-AI operates logs in to the PLC as an
8 word input (8WX) module. Analog values for each channel are reported to the PLC in the
corresponding input word. In Classic mode, the module operates in the 0-5V range (for
voltage inputs) or 0-20mA range (for current inputs). To operate the module in other ranges,
you must change to Classic Plus mode.
1.4.2 Classic Plus Mode
In Classic Plus mode (or High Density) operation, the 2500-8-AI operates logs in to the PLC
as an 8 word input / 8 word output (8WX/8WY) module. Analog values for each channel are
reported to the PLC in the corresponding input word. The WY output words are used to
allow the PLC to select the input signal range for the module.
For example, if the module is in Classic Plus mode and is logged in at address 1:
WX1 = input channel 1
WX2 = input channel 2
WX3 = input channel 3
WX4 = input channel 4
WX5 = input channel 5
WX6 = input channel 6
WX7 = input channel 7
2500C-8-AI Installation and Operation Guide

WX8 = input channel 8
WY9 = configuration channel 1
WY10 = configuration channel 2
WY11 = configuration channel 3
WY12 = configuration channel 4
WY13 = configuration channel 5
WY14 = configuration channel 6
WY15 = configuration channel 7
WY16 = configuration channel 8
In Classic Plus mode, the PLC can select range operation from any of the following by
setting the appropriate bits in the corresponding WY word for each channel. In addition, the
PLC can enable or disable digital filtering for each channel.

Reporting of Analog Values to the PLC
The module reports the converted analog value for each channel into the corresponding WX
word. The data is scaled according to the “0-32000” convention usually used in 2500
Series® PLC applications. A “0” indicates 0V or 0mA. A “32000” indicates full scale volts or
mA, with the level depending on the range being used.
The data is reported to the PLC in the format shown below:

In addition to applying a basic scale of 0-32000, the module provides a small overrange
capability to convert voltages above the full scale. The maximum valid reading is +32749.
Values above +32749 or below -32749 indicate error conditions.
Two error conditions are reported:
Overrange – means the input voltage is higher than the maximum that can be converted
(example: 5.117V for the 0-5V range). For this error, a value of “32759” is reported.
Underrange - means the input voltage is lower than the minimum that can be converted (-((example: -5.117V for the +5V range). For this error, a value of “32758” is reported.
The table below shows how the module reports for various input signals and range
selections.

Installation Planning
2.1.1 Safety Considerations
Before installing the module, you must identify the personnel hazards that may be created in
the event of a system failure and provide interlocks and safety switches to prevent operation
during a system failure. Refer to the NEMA ICS 3-304 Programmable Control Standards.
WARNING
As a system designer, you should be aware that Control devices can fail in an unsafe condition. Unless
you incorporate proper safeguards, malfunction of the controller or associated devices, such as
operator interface equipment, could cause sudden equipment startup, shutdown, or other unexpected
operation. Such startup or shutdown or unexpected operation could result in death or serious injury to
personnel, and/or damage to equipment.
If you or your company are using CTI controllers with equipment that requires the presence of a person
(such as an operator or attendant), you should be aware of this potential safety hazard and take
appropriate precautions.
The precautions below conform to the National Electrical Manufacturers Association
guidelines for installation of programmable controllers as recommended in the NEMA ICS 3–
304 Programmable Control Standards.
ICS 3-304.81 Safety Recommendations:
Consideration should be given to the use of an emergency stop function which is
independent of the programmable controller. Where the operator is exposed to the
machinery, such as in loading or unloading a machine tool, or where the machine cycles
automatically, consideration should be given to the use of an electromechanical override or
other redundant means, independent of the programmable controller, for starting and
interrupting the cycle. If provision is required for changing programs while the equipment is
in operation, consideration should be given to the use of locks or other means of assuring
that such changes can be made only by authorized personnel. These recommendations are
intended as safeguards against the failure of critical components and the effects of such
10
2500C-8-AI Installation and Operation Guide
failures or the inadvertent errors that might be introduced if programs are changed while the
equipment is in operation.
Operator Safety Switches
Power should be configured so that it can be manually removed from all output devices. You
must provide a method that is independent of the control system for disconnecting power
from the outputs when a machine is not operating or the operator must reach into the
machine. A non-electronic switch or directly wired relay must be used to disconnect the
power.
Emergency Stop Switch
You must provide a method for disconnecting power from the outputs if an emergency
situation is encountered with the machine operation. Use a non-electronic switch or relay
that is wired external to the controller and that is easily accessible.
2.1.2 Electrical Interference
Electrical interference can adversely affect the operation of control equipment. The major
sources of electrical interference in an industrial environment are devices that use high
voltages and current, such as motors and welders. Electrical interference can be conducted
directly through wiring or inducted via electromagnetic coupling.
To ensure a reliable control system, you will need to determine the source of the electrical
interference and employ suitable techniques to eliminate it.
2.1.3 Grounding
It is very important that the all equipment is properly grounded. Lack of proper grounding
may cause intermittent or erratic operation or may cause the control system to fail. A
properly installed grounding system will provide a low-impedance path to earth ground,
which will give all PLC internal filtering devices a good ground return for reference. The
earth ground of the building site typically provides reliable grounding; however, if excessive
ground current is present, a separate grounding electrode should be installed.
A common practice is to provide a central ground bus bar as a single point of reference
within each enclosure, connecting all chassis and power supply components to the bus bar.
The bus bar is then connected to earth ground. When connecting to the bus bar, use 1 inch
copper braid or No. 8 AWG wire. To ensure good connections, scrape paint or other nonconductive coatings away from mounting studs and from enclosure surfaces where
mounting bolts and washers make contact.
In addition to connecting the controller rack and power supply to earth ground, you must
ensure that the power supply, controller and all modules installed in the base are installed
securely and that the thumbscrews are tightened.
2500C-8-AI Installation and Operation Guide
11
2.1.4 Defining Operation Mode and Range Selections
Before you can install the module, you must review your planned input signals by channel
and decide on both the operation modes (Classic or Classic Plus), and the range selections
(Voltage or Current) for each input. If your application needs only 0-5V or 0-20mA (and
digital filtering enabled) for every channel, then you may use Classic mode. All other ranges
and options require the selection of Classic Plus mode.
2.1.5 Power Requirements
The 2500C-8-AI module consumes 0.75 watts of +5VDC power. To calculate the total power
required for the base, you need to add the power requirements for the other modules you
will install in the base.
2.2
Unpacking the Module
Open the shipping carton and remove the special anti-static bag that contains the controller.
After discharging any static build-up, remove the unit from the static bag. Do not discard the
static bag; use it for protection against static damage when the module is not inserted into
the I/O base.
CAUTION
The components on the 2500C-8-AI printed circuit card can be damaged by static electricity
discharge. To prevent this damage, the module is shipped in a special anti-static bag. Static
control precautions should be followed when removing the module from the bag and when
handling the printed circuit card during configuration.
2.3
Configuring the Module
Prior to inserting the module in the base, you must first configure it for operation based on
your requirements identified in Section 2.1.4 above. Configuration includes selecting
operation mode and selecting voltage or current for each channel. In addition, if you have
selected Classic Plus mode, you must configure your PLC program to set the necessary bits
in the WY word for the module.
12
2500C-8-AI Installation and Operation Guide
2.3.1 Selecting Operation Mode
The module operational mode is selecting using the jumper at JP11. For Classic mode, the
jumper should be installed at the “LD” position. For Classic Plus mode it should be installed
at the “HD” position. The module ships from the factory set for Classic mode operation.
2.3.2 Selecting Voltage or Current for Each Channel
Voltage or current mode is set for each channel using JP2 – JP9. For voltage mode place
the jumper in the “V” position. For current mode, place the jumper in the “I” position. The
module ships from the factory with jumpers in the “I” position.
NOTE
Note that in addition to setting the V / I jumper for each channel, you must wire your input to the
corresponding V or I terminal on the I/O connector. For more information, see Section 2.5
Connecting Field Wiring.
2500C-8-AI Installation and Operation Guide
13
2.3.3 Factory Default Settings
The 2500C-8-AI ships from the factory configured for Classic mode and current operation on
each channel. This means each channel is configured for 0-20mA operation.
JP11 = Classic or LD position
JP2 – JP9 = “I” position
Note that in Classic mode, digital filtering is ON. To disable digital filtering, you must
operate in Classic Plus mode.
2.4
Physical Installation
Remove AC power from the rack. Align the circuit board with the connector next to the
power supply. Slide the controller into the rack until the connector seats. Use the
thumbscrews to secure the controller in the rack.
IMPORTANT NOTE:
The 2500-8-AI is designed to allow “hot-swapping” the module under power in the event that
a replacement is needed. When “hot-swapping” the module, use the following procedure.
Make sure all field devices connected to the module are placed into a “safe” state
Remove the I/O connector from the front of the module
Loosen the module retaining screws and remove it from the base
Ensure the jumper configuration of the replacement module matches the one just
removed
5. Install the replacement module and tighten the retaining screws. The replacement
module must be the same model number as the one removed.

main office at 1-800-537-8398 or go to www.controltechnology.com/support/repairs/.
When returning any module to CTI, follow proper static control precautions. Keep the
module away from polyethylene products, polystyrene products and all other static
producing materials. Packing the module in its original conductive bag is the preferred way
to control static problems during shipment. Failure to observe static control precautions may
void the warranty.
