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.
