1. Before Using the Product
This chapter provides information you should know before using the product.
About the Module
Congratulations on your recent purchase of an Isolated Analog Input Module.
The ADI16-4(FIT)GY can be connected to the F&eIT series of controller modules (such as the
CPU-CAxx(FIT)GY and CPU-SBxx(FIT)GY) to construct a system.
The isolation between external signals and the Controller Module permits the use of the Controller
Module without compromising the communications features of the latter.
Please read this manual carefully to create application programs and configure the system, such as
setting the switches and connecting it to external devices.
Features
- Bus-isolated analog input module providing high precision at a resolution of 16 bits.
- Selectable input ranges common to channels: Bipolar input from -10 to +10 V and current input
from 0 to 20 mA.
- Support for differential input, capable of accurate measurement of voltages over a distance from
the signal source or with potential differences.
- A rotary switch allows you to set device IDs to help you keep track of device numbers.
- Flanged two-piece connector used to prevent disconnection from the connector on the controller
module.
- Similar to other F&eIT series products, the system, in the module itself, incorporates a 35-mm
DIN rail mounting mechanism as a standard item. A connection to a controller module can be
effected on a lateral, stack basis in a unique configuration, which permits a simple, smart system
configuration without the need for a backplane board.

from the controller module. For details, see Chapter 4 “Using the I/O Address Map”.
Control using the memory address map
When connected to the CPU-CAxx(FIT)GY, the ADI16-4(FIT)GY can be accessed from the host
computer over the network. The ADI16-4(FIT)GY is assigned with its device ID in the memory
managed by the controller module. The application running on the host computer controls the module
by reading/writing the memory managed by the controller module. For details, see Chapter 5 “Using
the Memory Address Map”.
Control via the Windows driver
For the functions and settings available when using the Windows driver, refer to the reference manual
and online help for each module.
Control over the web
You can monitor collected data and manage the log over the web. You can use your familiar browser
to easily make various settings. For details, refer to the reference manual for the SVR-MMF(FIT)GY.

In the figure, the indicated switch settings represent factory settings.
Figure 2.1. Names of module components
Setting a Device ID
The controller module distinguishes and keeps track of the modules that are connected to it by
assigning device IDs to them. Each module, therefore, should be assigned a unique ID.
A Device ID can be assigned in a 0 to 7 range, so that a maximum of eight modules can be
distinguished.
Setup Method
A device ID can be set by turning the rotary switch on the device face.
To set a device ID, turn the switch knob.

How to Connect an Interface Connector
When connecting the Module to an external device, you can use the supplied connector plug.
To wire each terminal, strip the wire about 9 to 10 mm from the end and insert it into the opening.
After inserting the wire, tighten the screw to fasten it. Compatible wires are AWG 28 to 16.

Analog Signal Connection
Differential input connection examples
This section gives examples of connecting analog input signals from an external device to the Module
using a flat cable and a shielded cable.
The following example uses a flat cable to connect the Module to an external device.
Connect the [+] and [-] analog input channels of the Module to the output and ground of the signal
source, respectively. Also connect the analog ground of the Module to the ground of the signal source.
*1 When using a ceramic capacitor, make the lead as short as possible.
Figure 3.3. Differential input connection (Flat Cable)
The following example uses a shielded two-conductor cable to connect the Module to an external
device. Use this type of cable if the signal source is located at a distance from the Module or if the
connection requires higher noise immunity. Connect the [+] and [-] analog input channels of the
Module to the output and ground of the signal source, respectively. Also connect the analog ground of
the Module to the ground of the signal source using the shield braid.
Figure 3.4. Differential input connection (Shield Cable)
- If the signal source contains over 1MHz signals, the signal may effect the cross-talk noise between
channels.
- Converted data is undefined with the analog ground unconnected.
- If the connecting cable is affected by noise, accurate analog input may not be made. To secure the
accuracy, place the connecting cable far from the source of the noise and put a laminated ceramic
capacitor on the connector of the module.
- When affected by noise, the connection cable may fail to input accurate analog signals. Route the
connection cable apart from noise sources.
- The connection cable may fail to input accurate analog signals if it is long. The connection cable
should therefore be as short as possible.

ADI16-4(FIT)GY 13
- The analog signal input to the [+] and [-] inputs must not exceed the maximum input voltage with
reference to the analog ground of the module. Exceeding the input voltage can damage the
module.
- Converted data is undefined when either of the [+] and [-] input terminals is left unconnected.
Connect both of the [+] and [-] input terminals of the channel not connected to the signal source to
the analog ground.
Current source connection examples
This section gives examples of connecting analog input signals from an external device to the Module
using a flat cable and a shielded cable.
The following example uses a flat cable to connect the Module to an external device.
Connect the [+] and [-] analog input channels of the Module to the positive and negative outputs of the
current source, respectively. Also connect the analog ground of the Module to the ground of the signal
source.
Note also that, when there are more than one current source, no potential difference must exist
between their respective GND points.
The ADI16-4(FIT)GY is isolated between its internal CPU and the external device but not between the
analog input channels and thus uses a common analog ground.
If an affecting potential difference exists between the channels, insert an isolator such as an isolating
transducer between the channels.
*1 When using a ceramic capacitor, make the lead as short as possible.
Figure 3.5. Current input connection
- Converted data is undefined with no analog ground connected.
- If the connection cable is affected by noise, the analog input can be inaccurate. Route the
connection cable apart from noise sources.
- If the connecting cable is affected by noise, accurate analog input may not be made. To secure the
accuracy, place the connecting cable far from the source of the noise and put a laminated ceramic
capacitor on the connector of the module.
- The analog signal input to the [+] and [-] inputs must not exceed the maximum input voltage with
reference to the analog ground of the module. Exceeding the input voltage can damage the
module.

4. Using the I/O Address Map
ADI16-4(FIT)GY 15
4. Using the I/O Address Map
Starting I/O Address
When connected to a CPU-SBxx(FIT)GY, the ADI16-4(FIT)GY can directly receive I/O commands
from the controller module. Depending on how the Device ID is set, the I/O addresses indicated
below will be used exclusively by the ADI16-4(FIT)GY.
Because the address bus on which the I/O address space is specified is not fully decoded in continued
16 bits, four starting I/O addresses exist in each Device ID.
If the Device ID is set to 0h, one of the four addresses (0800h, 0840h, 0880h, or 08C0h) will be used
as a starting I/O address.
Control examples are coded in C. Modify them in the appropriate language for the target OS or
development system.
