Current Source Digital I/O Board with Opto-Isolation

PIO-32/32RL(PCI)H

* Specifications, color and design of the products are subject to

change without notice.

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.

*1 The CD-ROM contains the driver software and User’s Guide.

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 supporting Win32 API functions, such as Visual Basic or Visual C++.

Connecting Input Signals

Connect the input signals to a device which can be current-driven, such as a switch or transistor output device. The connection requires an external power supply to feed currents. The board inputs the ON/OFF state of the current-driven device as a digital value.

The input circuits of interface blocks of this board are illustrated in the image above. The signal inputs are isolated by Optocoupler (corresponding to the current source output). The board therefore requires an external power supply to drive the inputs. The power requirement for each input pin is about 5.1mA at 24VDC (about

2.6mA at 12VDC).

Zener diode

PolySwitch

The output circuits of interface blocks of this board are illustrated in the image above. The signal output section is an Optocoupler isolated, current source output type. Driving the output section requires an external power supply. The rated output current per channel is 100mA at maximum. A zener diode is connected to the output transistor for protection from surge voltages. A PolySwitch-based overcurrent protector is provided for every eight output transistors. When the overcurrent protector works, the output section of the board is temporarily disabled. If this is the case, turn of the power to the PC and the external power supply and wait for a few minutes, then turn them on back.

CAUTION

When the PC is turned on, all output are reset to OFF.
