* Specifications, color and design of the products are subject to change
without notice.
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.

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.

50C ambient temperature.
*2 Available only when the ADI16-4(FIT)GYs connected to the CPU-SBxx(FIT)GY.
*3 For this product, as the analog signal is input to A/D converter without being processed in order not make the
frequency characteristics to deteriorate, if the connection cable is affected by noise, correct analog input may
not be achieved.
- When connecting one of the modules to a controller module, the internal power consumption should be
taken into account. If the total current exceeds the capacity of the power supply unit, the integrity of the
operation cannot be guaranteed. For further details, please see the Controller Module manual.
- Depending upon the specific controller module that is used, some of the functions are not supported.

Interface Connector
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.
Removing the connector plug by grasping the cable can break the wire.
Signal Layout on the Interface Connector
The Module can be connected to an external device using a 12-pin (1
group) connector that is provided on the Module face.
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.
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.
- 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.
- 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.
- 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.
- 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.
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.
Range Setting Switches
Set the voltage input or current input range setting depending on the
measurement target. The input range is common to all channels; it
cannot be set for each of them and must not be set to an invalid range.
Setup Method
To set the voltage or current input, use the corresponding DIP switch on
the module face.
See the following sketches for reference to set each DIP switch.
