CNT24-2(FIT)GY 1
F&eIT Series
Isolated Counter Module
CNT24-2(FIT)GY
*Specifications, color and design of the products are subject to
change without notice.
Congratulations on your recent purchase of an Insulator
Counter Module.
This product counts high-speed pulses so that the pulses can
be processed within a F&eIT-series controller module
<CPU-CAxx(FIT)GY, CPU-SBxx(FIT)GY etc>. As such, this
product can be used for position alignment control in
combination with an encoder. The insulation between
external signals and the Controller Module permits the use of
the Controller Module without compromising the
communications features of the latter.
This product can perform 24-bit up and down counting covering
two channels.
This product can count two-phase signals, such as rotary
encoders and linear gauges.
This product is equipped with general-purpose input signals,
with one point per channel.
A rotary switch allows you to set device IDs to help you keep
track of device numbers.
The system incorporates a screw less 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
module itself, incorporates a 35mm 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.

supply unit, the integrity of the operation cannot be
guaranteed. For further details, please see the Controller
Module manual.

use the supplied connector plug. When wiring the Module, strip
off approximately 7 - 8 mm of the covering for the cable, and
insert the bare wire by pressing the orange button on the
connector plug. Releasing the orange button after the wire is
inserted to fix the cable. Compatible wires are AWG 28 - 20.
Press this section to insert
the wire material.

CAUTION
The general-purpose input signal also has a similar circuit
configuration.
When an external power supply other than 5V is used,
insert a current-limiting resistor at position R. If PV
denotes an external power supply, the current-limiting
resistor R can be calculated as follows:
P - 5
20 < Rk<P - 5
15
For example, P = 12V will require the following resistance:
350< R < 470
When there is a match between a channel count and a
specified value, a one-shot (one pulse) match signal is output
to the outside. The signal output section has an open
collector configuration based on opto-isolation. Driving the
output of this module requires an external power supply.

CAUTION
A surge voltage protection circuit is not provided on the

driving relays, lamps, and other induction loads using this
Module, a surge voltage countermeasure should be
provided on the load side.

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 this product to the CNT24-2(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 that is
located on the module face.
A Device ID can be assigned by turning the switch.
