* Specifications, color and design of the products are subject to
change without notice.

Features

A different external power supply can be used for each
common pin as it is shared by 16 channels.
The PCI bus (personal computer) and the I/O interface are
isolated from each other by an Optocoupler, offering good
noise immunity.
You can use 32 signal channels of the input signals as interrupt
inputs.
You can also select the interrupt trigger edge of the input
signal.
The board has a digital filter feature to prevent noise or chatter
from causing erroneous inputs.
Up to 35VDC, 100mA per signal, max. output.
Zener diode connected to output transistors for protection from
surge voltage. Overcurrent protective device provided for
every eight channels of output transistors.

PIO-32/32RL(PCI)H
This board is a PCI bus-compliant interface board for
input/output of digital signals.
The board is a current source typed and isolated digital
input/output board and can input and output digital signals at
12 - 24VDC.
This board can input and output up to 32 channels.
This product uses Optocoupler isolated input (ready to accept
current sinking output signals) for input and Optocoupler
isolated current sinking output for output.
Using the bundled driver library [API-PAC(W32)], you can
create Windows application software for this board in your
favorite programming language
functions, such as Visual Basic or Visual C++.
