1. Before Using the Product
1. Before Using the Product
This chapter provides information you should know before using the product.
About the Module
This product is an expansion module (device module) that adds digital signal I/O interfaces to one of
various types of controllers. The product is used in combination with the I/O controller module
< CPU-CAxx(FIT)GY > (*1) or BOX-PC < BX-300-DC5xxx > (*1) or microcontroller unit
< CPU-SBxx(FIT)GY > (*1) in the F&eIT Series.
The < DIO-16/16(FIT)GY > can perform a maximum of 16 points of opto-isolated input and 16 points of
opto-isolated output per module. (Input: 12 - 24 VDC specified, output: 12 - 48 VDC specified)
The < DI-32(FIT)GY > can perform a m a ximum of 32 points of opto-isolated i np ut per m odule. (In p ut:
12 - 24 VDC specified)
The < DO-32(FIT)GY > can perform a maximum of 32 points of opto-isolated output per module.
(Output: 12 - 48 VDC specified)
By reading this manual carefully, please build a system by creating applications programs, setting the
switches, and connecting the module to external devices.
*1 This module is available in different product models. "x" in each model number represents a
blank or one alphanumeric character. This is applicable to the rest of this document.
Features
- A different external power supply can be used for each common pin as it is shared by 16 signal
points.
- The < DIO-16/16(FIT)GY > can perform 16-points digital signal input and 16-points digital signal
output.
- < DI-32(FIT)GY > can perform 32-points digital signal input.
- < DO-32(FIT)GY > can perform 32-points digital signal output.
- The output section is a high sink current, open collector type using high-capacitance transistors.
< DIO-16/16(FIT)GY >: 150 mA/24 VDC or 50 mA/48 VDC max. (per channel)
< DO-32(FIT)GY >: 150 mA/24 VDC or 50 mA/48 VDC max. (per channel))
- Input section is ready to accept both the current sinking output and current source output.
- Isolated I/O operations using an optocoupler improves noise immunity.
- The card has a digital filter to prevent input signals from carrying noise or a chattering.
- A rotary switch allows you to set device IDs, making it easy to keep track of device nu mbers.
- Like other F&eIT series products, the module has a 35mm DIN rail mounting mechanism as
standard. A connection to a controller module can be effected on a lateral, stack basis in a unique
configuration, which perm its a sim ple, sm art sy stem confi gura tion wi thout t he need for a bac kplane
board.
- You can use all of the input signals as interrupt in puts. You can al so select the i nterrupt tri gger edge
of the input signal.

1. Before Using the Product
Functions
Generic I/O functions (data I/O operations that directly access the I/O ports)
- Input
The Module transmits a maximum of 32 points (< DI-32(FIT)GY >) or 16 points
(< DIO-16/16(FIT)GY >) of externally supplied digital signals to a controller module that is connected
to it. Access to the Module from a controller module is performed through the input port that is
specified by means of a Device ID. When an input port is read by the execution of an input command,t
he buffer gate associated with the input port is opened, and the digital signals supplied from an
external device are fetched in groups. During this operation, if the module is the DI-32(FIT)GY,
DIO-16/16(FIT)GY, signals that are transmitted to the controller module will be [ON (closed): 1, OFF
(open): 0].
- Output
The Module writes a maximum of 32 poi nts (< DO-32(FIT)GY >) or 16 points (< DIO-16/16(FIT)GY >)
of digital signals to an external device. Access to the Module from a controller module is performed
through the output port that is specified by means of a Device ID. When data is written to the output port
by the execution of an output command, the data is held on the latch circuit that is associated with the
output port. After being electrically isolated by an optocoupler, if the module is the DO-32(FIT)GY,
DIO-16/16(FIT)GY, the digital signals are transmitted to the connected external device through
transistors. During this operation, signals that are transmitted to the external device will be [ON
(closed): 1, OFF (open): 0].
Output data monitoring function
This function allows you to keep track of the signal data that is being output.

the network. The module 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
Control over the web – Connecting to the SVR-MMF2(FIT)
You can monitor collected data and manage the log over t he w eb. You can use your familiar browser to
easily make various settings. For details, refer to the reference manual for the SVR-MMF2(FIT).

2. Module Nomenclature and Settings
Setting a Device ID
The controller module distinguishes and keeps track of the modules that are c onnecte d to it by ass igning
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 t hat a m a ximum of eight modules can be distinguis hed.
The factory setting for the Device ID is [0].
Setup Method
A Device ID can be set by turning the rotary switch that is located on the module face.
A Device ID can be assigned by turning the switch.

How to Connect an Interface Connector
When connecting the Module to an external device, you can use the supplied connector plug.
When wiring the Module, strip off approximately 9 - 10mm of the covering for the cable, and insert the
bare wire by pressing the orange button on the connector plug. Releasing the orang e button af ter the
wire is inserted fixes the cable. Compatible wires are AWG 24 - 16.

Figure 3.5 shows the input equivalent c ircuit for t he interfac e section of the < DIO- 16/1 6(FIT)GY > a nd
< DI-32(FIT)GY >.
The signal input section consists o f an opto-i solate d inpu t (com patible wi th both c urre nt sink ou tput a nd
current source output). An external power s upp ly is th erefore requ ired to driv e the inpu t section of this
module. The power requirement for t he < DIO-16/16(FIT) GY > or < DI-32(FIT) GY > is about 8 mA per
input channel at 24 VDC (about 4 mA at 12 VDC).

Output section
Figure 3.8 shows the output circuit for the interface section of the < DIO-16/16(FIT)GY > and
< DO-32(FIT)GY >. The signal output section consists of an opto-isolated open collector output
(current sink type). An external power supply is therefore required to drive the output section of this
module.
The maximum output current rating per channel is 150 mA for the < DIO-16/16(FIT)GY > or
< DO-32(FIT)GY > (at 12 - 24 VDC) or 50 mA for the < DIO-16/16(FIT)GY > or < DO-32(FIT)GY >
(at 36 - 48 VDC). A surge voltage protection circuit (zener diode) is provided for the output transist ors
of this module. When the module drives relays, lamps, and other indu ction lo ad s, however, an other
surge voltage countermeasure should be provided on the load side.
CAUTION
When the power is turned on, all output will be OFF.
