Introduction
1. Introduction
Congratulations on your recent purchase of an Insulator Digital Input Module.
By converting external analog voltage signals into digital data, the ADI12-8(FIT)GY
can process them inside the F&eIT series controller module < CPU-CAxx(FIT)GYGY,
CPU-SBxx(FIT)GY etc >.
The insulation 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
- The input range is common to different channels, and can be selected from four input
ranges, including unipolar and bipolar ranges.
- The ability to accommodate differential input permits the accurate measurement of
voltage values over long distances from the signal source and even under a
considerable potential difference.
- A rotary switch allows you to set device IDs to help you keep track of device
numbers.
- The system incorporates a screwless connector plug that allows you to easily attach
and detach wires without using any special tools.
- Similar to other F&eIT series products, the system, in the m odule itsel f, incor porates
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.

Module Nomenclature and Settings
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 - 7 range, so that a maximum of eight modules can
be distinguished.
To connect the ADI12-8(FIT)GY to the ADI12-8(USB)GY, assign a device ID between
1 and 3.
The factory setting for the Device ID is [0].
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.

ADI12-8(FIT)GY
Connecting to an External Device
Example of connecting a current input
To measur e a current using t he ADI12-8(FI T)GY, you need to convert the current into a
voltage using a resistor.
By connecting a 250Ω resistor between the [+] and [-] inputs, the ADI12-8(FIT)GY can
measure currents from a 0 - 20mA current output de vice in a voltage input range fr om 0
to 5 V. Note that, if the inserted resistor has a considerable error, it adversely affects
converted data, preventing accurate measurement. You should therefore use a precision
resistor (±0.1 %) on the connector side.
Note also that, when there are more than one current source, no potential difference
must exist between their respective GND points.
The ADI12-8(FIT)GY is insulated between its internal CPU and the e xternal de vice 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 insulator such
as an insulating transducer between the channels.

Notes!
- Converted data is undefined with no analog ground connected.
- If the connection cable is affected by noise, the analog input can be inaccurate.
- The analog signal input to the [+] and [-] inputs must not exceed the maximum

Using the I/O Address Map
4. Using the I/O Address Map
Starting I/O Address
When connected to a CPU-SBxx(FIT)GY, the ADI12-8(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 ADI12-8(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, 08 80h, or 08C0h)
will be used as a starting I/O address.
