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.

Counter Input Circuit and Control Input Circuit
The figure below shows the equivalent circuit of counter input section
and control input section of this product.
The signal input section consists of an opto-coupler isolated input
(compatible with current sink output). Set an external power voltage and
input resistance value according to the output specification of the
external device to be connected.
As for the counter input section, connect both phase A and phase B for a
two-phase input.
Connect either phase A or phase B for a single-phase input. If not using
the Z phase, this does not need to be connected.
In addition, the control input section can also be used as the input
section for the start / stop signal of general-purpose input and count
operation, preset signal of count value.

CNT-3204IN-USB 4
To use external power (other than 5V or 12V); insert a current limiting resistor at the R position.
The following expression is used to calculate current limiting resistance R with the external power supply as PV:
The expression is as follows;
If PV=24V, use a 600Ω < R < 800Ω resistor.
Control Output Circuit
The figure below shows the output circuit of control output section of
this product. The signal output section consists of an opto-coupler
isolated open collector output (current sink type). An external power
supply is therefore required to drive the output section of this product.
The maximum output current rating per channel is 50 mA for the
product.
Zener diodes are connected to the output transistor to protect against
surge voltages. As for the control output section, it is also possible to
output a one-shot pulse signal at the time of hardware event occurs,
such as a general-purpose output and count match.
- Negative logic is set as default. (Negative logic is also set when setting is empty)
- When the power is turned on, all output will be OFF.
Sampling Control Input Circuit
The figure below shows the circuit of signal input for sampling control
section of this product. These inputs are used for the start signal, the stop
signal and the clock signal of sampling operation. The signal input
section consists of a digital isolated and TTL input. This section can set
the pull-ups, so that the device that outputs a TTL level signal and also
the device that outputs an open-collector can be connected. The pull-up
voltage is 5V. If it is necessary to pull-up with different voltage such as
3.3V, turn off the pull-up setting and pull-up at the external device side.
Turn on the pull-up setting when sampling control input is not used. It may affect the unconnected control
input terminal when pull-up voltage is not connected.
Setting Switches
There are two setting switches. “x16” and “x1” represent high bits and low
bits of Module ID respectively.
Factory settings “00” can be used when only one device per model is
connected to one computer. Each device should be assigned a unique
Module ID in the range of 00 - 7Fh when several devices with the same
model are being connected.
