N Series for USB
Isolated 32-bit Up/Down Counter Unit
CNT-3204IN-USB
* Specifications, color and design of the products are subject to change
without notice.
This product is a USB 2.0 supporting counter unit, which adds the
function of counting pulse signals input from external devices through a
USB port to a PC.
It has four channels of 32-bit up/down counters, allowing external
devices such as a rotary encoder and a linear scale to be connected.
The pulse signal inputting interface is optocoupler isolated.
Compact design, (188.0(W)×78.0(D)×30.5(H)mm), features flexibility in
installation. The product can be set on the floor, wall, and inside the
console or equipment with the DIN rail.
Input interface of pulse signal is opto-coupler isolated input.

Features
32-bit up-and-down counter
The 32 bit up-and-down counter could have four channels and up to
500kHz maximum speed pulse input. Moreover, it can count 2-phase
signals and mono-phase signals such as a rotary encoder and a linear
scale.
Bus isolation
The USB (PC) is isolated from I/O interface by an isolators, this product
has excellent noise performance.
Control input/output signals and input signals for controlling sampling
functions
One control input signal and one control output signal are provided for
each channel. This product can generate an interrupt, output an external
signal, preset the counter, and clear it to zero when the count value
matches the arbitrary value that is set. Moreover, this product has input
signals (start/stop/clock) for controlling sampling functions.
Compact design not restricting installation location
Compact design of 188.0(W) × 78.0(D) × 30.5(H) does not require special
installation location.
Compatible to USB1.1/USB2.0
Compatible to USB1.1/USB2.0 and capable to achieve high speed
transfer at High Speed (480 Mbps)
Diverse installations such as screw fastening, with
magnet(optional),and DIN rail mounting are possible
Installation on the floor / wall /ceiling is possible by screw fastening, with
magnet, rubber feet, etc. In addition, DIN rail mounting mechanism is
equipped as standard with the product, making it easy to install the
product within the panel or the device.
Easy-to-wire terminal connector adopted
Adoption of terminal connector (with screws) enables to achieve easy
wiring.
Windows compatible driver software
Using the counter input driver API-CNT(WDM) for USB makes it possible
to create applications of Windows. In addition, a diagnostic program by
which the operations of hardware can be checked is provided.
