About the Board
This product is a PCI Express bus compliant counter input board which counts the pulse signal input
from an external device.
8 ch 32-bit up/down counter is mounted, and the bus master transfer function makes it possible to
transfer data at a high speed by high speed pulse input (unisolated TTL-level input, differential line
receiver) up to 10MHz. In addition, 2-phase signals and 1-phase signals such as a rotary encoder or
linear scale can be counted.
With the driver libraries for Windows supplied as standard, applications with CONTEC hardware
features fully utilized can be created.

Features
8ch 32-bit up/down counter, high speed pulse input of 10MHz, and disconnection detection are
available.
A 32-bit up/down counter with 8 channels is mounted on one board, high speed pulse input up to
10MHz (unisolated TTL-level input, differential line receiver) is available, and disconnection detection
can be performed for differential line receiver input.
2-phase signals and 1-phase signals such as a rotary encoder or linear scale can be counted. Surge
protection is realized by implementing protectors in the input circuit.
In addition, 1pin/ch of control input signal is provided. It can be used as counter start/stop, preset, zero
clear, general-purpose input.
Bus master transfer function is provided.
Bus master transfer makes it possible to transfer large data at a high speed without extra CPU load at a
sampling rate up to 20MHz.
Digital filter function to prevent wrong recognition of input signals due to noises is provided.
Digital filter function by which noises of counter input signals (phase-A, phase-B, phase-Z) and control
input signals can be prevented is equipped. Digital filter can either be not used or set within the range of
0.1μ - 1.6384msec by software.
In addition, as all these input signals are taken into the internal counter via the digital filter, when using
the digital filter, these signals are taken in with a delay of a specified duration.
