CTI P/Ns: 2558 Quick Start Guide: 062-00347-011
2558 Installation and Operation Guide: 062-00331-012
Summary: The 2558 is designed to translate an analog input signal into an equivalent digital word to
the programmable logic controller (PLC). Configuration of the module, taken from the full-length
2558 Installation and Operation Guide’s Chapter 2, is as follows.
2.3. Configuring the Module
The Model 2558 must be configured for voltage or current inputs, voltage range, unipolar/bipolar
mode, digital filtering/no filtering mode, return commonality, and 13 or 16 bit compatibility before
wiring the input connectors and inserting the module into the I/O base. As shipped, all input channels
are configured for current inputs, 5V range (see note below), unipolar mode, digital filtering enabled,
offset scaling disabled, a common return, and 13 bit compatibility (see Figure 2.1).
NOTE:
The 5V input signal range configuration is used for both 0 to 5VDC and 1 to 5VDC or
0 to 20mA and 4 to 20mA input signal ranges.
Changing the module input channel configuration involves the following steps (notations in
parenthesis are actual printed board titles) described in the following sections:

2.3.1. Selecting Voltage or Current Input Mode
Locate the 8 Voltage/Current Jumpers corresponding to input channels 1 through 8. See Figure 2.2
for the location of these jumpers. For each input channel, select current mode by placing the jumper
in the “20MA” position or voltage mode by placing the jumper in the “VOLTAGE” position. For
each input channel set to current mode, you must set the corresponding Voltage Range Jumper to the
5V position as described in the following section. As shipped, the jumpers are in current mode.
CTI 2558 Quick Start Guide

2.3.2. Selecting Voltage Range
Locate the Voltage Range Jumpers corresponding to input channels 1 through 8 (see Figure 2.2). For
each input channel operating in current mode, set the corresponding Voltage Range Jumper to 5V.
CAUTION:
For each input channel configured for current mode, the corresponding Voltage Range Jumper
must be set to 5V.
For each input channel operating in voltage mode, set the corresponding Voltage Range Jumper to
“5V” for 0 to +5V or –5 to +5V input range or “10V” for 0 to +10V or –10 to +10V input range. As
shipped, the 2558 is in “5V” range.

2.3.3. Selecting Unipolar or Bipolar Input Mode
Locate the Unipolar/Bipolar Jumpers for each channel (see Figure 2.2). Set each jumper to “UNI” for
unipolar operation or “BI” for bipolar operation for each input channel. As shipped, “UNI” operation
is selected.

(jumper settings shown as shipped)
2.3.4. Selecting Digital Filtering
Locate the Digital Filtering Jumper “DIG FILTER” JP25 (see Figure 2.2). To enable digital filtering,
set the jumper in the “EN” position; to disable, set to the “DIS” position. Since many analog input
signals contain noise, CTI recommends using digital filtering unless maximum response time is
required. As shipped, digital filtering is enabled for all 8 analog inputs.
CTI 2558 Quick Start Guide

2.3.5. Selecting Offset Scaling
Locate the Offset Scaling “OFFSET” jumper JP40 (see Figure 2.2). To enable offset scaling for all 8
inputs set the jumper to the “EN” position; to disable, set to the “DIS” position. As shipped, the
Offset Scaling is disabled.
2.3.6. Selecting Compatibility Mode
Locate the Compatibility Mode “CMPBTY MODE” jumper JP26 (see Figure 2.2). To enable 16 bit
compatibility mode for all 8 inputs set the jumper to the “16BIT” position. As shipped, the 13 bit
compatibility mode is enabled.
2.3.7. Configuring Switches to Report Hardware Configuration
Once the hardware jumpers are selected this information needs to be reported to the microcomputer.
The information is reported via DIP switches SW1 and SW2 (see Figure 2.2). Each output channel
uses 2 switches with a BCD code to indicate the state of the hardware jumpers.

NOTE:
The OFF position is selected by actuating the switch in the direction of the center of the printed
circuit board.
NOTE:
Standard shipping configuration is all switches in the OFF position Unipolar 5VDC range.
2.3.8. Selecting Channel Return Path as Common or Isolated
Locate the return jumpers 1-8 (see Figure 2.2). To enable a common channel 1-8 return path, select
the “COM” (common) position. To isolate individual channels, choose the “ISO” (isolated) position.
As shipped, all 8 channels are in “COM” (common) mode.
2.3.9. Jumper Settings for Future Reference
See Appendix B. Jumper Settings Log Sheet to record any changes to the module’s jumper settings.

CTI 2558 Quick Start Guide
2.4. Inserting the Module into the I/O Base
Insert the module into the I/O base by carefully pushing the module into the slot. When the module
is fully seated in the slot and backplane connector, tighten the captive screws at the top and bottom
to hold the module in place. To remove the module from the I/O base, loosen the captive screws then
remove the module from the I/O base. Be careful not to damage the edge card at the back of the
module when inserting or removing the module.
2.5. Wiring the Input Connectors
Input signals are accepted through a connector assembly located on the front of the module. The
connector assembly consists of a standard Siemens® front panel edge connector that mates with the
printed circuit board. Wiring is connected to the front connector via recessed screw terminals. The
screw terminals can accept wire sizes up to single stranded 14-gauge wire. The actual size used
depends on the external device providing the input signal. Consult the device manufacturer’s
recommendations for selecting the input wire size.
To assign an input to a specific channel, locate the appropriate channel position on the screw
terminal connector as shown in the following figure:
Figure 2.3 Screw Terminal Connector Wiring
2.5.1. Connecting Voltage Input Wiring
For voltage input circuits, connect the signal wire to the V# In screw terminal, and the return wire to
the Return# screw terminal. Insert the wires in the appropriate holes on the front of the connector.
CTI 2558 Quick Start Guide

When the wires are inserted, tighten the screws. Repeat this procedure for the remaining voltage
input channels.
2.5.2. Connecting Current Input Wiring
For current input circuits, connect the signal wire to the I# screw terminal, and the return wire to the
Return# screw terminal. Insert the wires in the appropriate holes on the front of the connector. When
the wires are inserted, tighten the screws. Repeat this procedure for the remaining current input
channels.
2.5.3. Connecting the Shield Wiring
Control Technology Inc. recommends that all wires be shielded twisted pair with a foil wrap shield
and a separate drain wire and that they be installed in a metallic conduit. Use Belden cable 8761 or
equivalent which contains a foil wrap shield and a separate drain wire. The shield and the foil wrap
should be twisted together and should be terminated at only one end. The other end should be left in
an open circuit condition. CTI recommends that the shield be terminated at the PLC end of the signal
wire. Special components are installed on the module to aid in the rejection of noise.
When entering the industrial cabinet the shield should be routed from the main terminal strip all the
way to the PLC. Signal leads that do not maintain a shield from the terminal strip to the PLC act as
antennas and are susceptible to radiated and conducted emissions in the cabinet. Unprotected cables
may introduce measurement errors in the module.
The front connector on the module contains a CHASSIS terminal which may be used for the shield
wire if the installation is in a noise free environment. If the installation is in an extremely noisy
environment CTI strongly recommends that the shielded wires terminated to the PLC chassis ground.
CTI has exhaustively tested this product to maximize its ability to reject noise from inductive sources
as well as showering arcs, fast transients and other high frequency generators and has determined
that the best performance results from connecting all shield wires together at the PLC module and
terminating this single wire to the chassis ground with a large current capacity conductor. CTI
recommends using a #8 gauge wire are larger from the PLC chassis to the earth ground connection.

2.7. Checking Module Operation
First turn on the base power. If the module diagnostics detect no problems, the status indicator on the
front of the module will light. If the status indicator does not light, begins blinking (or goes out
during operation), the module has detected a failure. For information on viewing failed module
status, refer to your TISOFT user manual. To diagnose and correct a module failure, refer to the next
section on troubleshooting.
You must also check that the module is configured in the memory of the PLC. This is important
because the module will appear to be functioning regardless of whether it is communicating with the
PLC. To view the PLC memory configuration chart listing all slots on the base and the inputs or
outputs associated with each slot, refer to your TISOFT Programming Manual. An example chart is
shown in the following figure.
Figure 2.6 Example I/O Configuration Chart
In this example, the Model 2558 module is inserted in slot 1 in I/O base 0. Data for channel 1
appears in word location WX1, data for channel 2 appears in word location WX2, etc. For your
particular module, look in the chart for the number corresponding to the slot occupied by the module.
If word memory locations appear on this line, then the module is registered in the PLC memory and
the module is ready for operation.
If the line is blank or erroneous, re-check the module to ensure that it is firmly seated in the slots.
Generate the PLC memory configuration chart again. If the line is still incorrect, contact your local
distributor or CTI at 1-800-537-8398 for further assistance.

CHAPTER 3. TROUBLESHOOTING
If the module provides improper readings or the status indicator is not on, use the following chart to
determine the appropriate corrective action.
Figure 3.1 Troubleshooting Matrix
CAUTION:
The module fuse F2 is not user serviceable. If this fuse is blown, the module has a serious
component failure and should be returned to CTI for repair.
When it is inconvenient to visually check the status indicator, use the TISOFT “Display Failed I/O”
or “Show PLC Diagnostics” support functions.
If after consulting the chart above, you are unable to diagnose or solve the problem, contact your
local distributor or CTI at 1-800-537-8398 for further assistance.

APPENDIX A. COMPATIBILITY WITH SIEMENS® 505-6108A/B
Overview
The CTI 2558 Analog Input Module was designed to be a drop-in replacement for the Siemens®
models 505-6108-A and 505-6108-B. From set up of the module to wiring and PLC reporting, the
user will find many similarities between the CTI and Siemens® models.
Using the CTI 2558 in a 505-6108-A and/or 505-6108-B application
The CTI 2558 should fulfill all the following requirements for the 505-6108-A and 505-6108-B
replacement(s), as outlined below:
Module setup
Since the CTI 2558 allows for both Unipolar and Bipolar setup, the module does have a slightly
different module setup. See Chapter 2.3 Configuring the Module for Operation to determine the
details in module setup.
Wiring
The wiring of the input connector is the same between the module. See Chapter 2.5 Wiring the
Output Connector for a detailed explanation of how this is accomplished.
PLC Reporting
The word format is the same between the modules. See Chapter 1 for a more detailed explanation on
PLC reporting.
