such as Visual Basic or Visual C/C++.

PO-32L(PCI)H

with Driver Library [API-PAC(W32)]

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 opto-coupler, offering good noise immunity.

- You can use all of the input signals as interrupt inputs. You can also select the interrupt trigger edge of the input signal.
<PIO-16/16L(PCI)H>, <PI-32L(PCI)H>

- The board has a digital filter feature to prevent noise or chatter from causing erroneous inputs.
<PIO-16/16L(PCI)H>, <PI-32L(PCI)H>

- Up to 35VDC, 100mA per signal, max. output.
<PIO-16/16L(PCI)H>, <PO-32L(PCI)H>

- Zener diode connected to output transistors for protection from surge voltage. Overcurrent protective device provided for every eight channels
of output transistors.

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.

Input pin

The input circuits of interface blocks of the PIO-16/16L(PCI)H and
PO-32L(PCI)H are illustrated in Figure 3.5. The signal inputs are
isolated by opto-couplers (ready to accept current sinking output
signals). The board therefore requires an external power supply to
drive the inputs. The power requirement for each input pin is about

5.1 mA at 24 VDC (about 2.6 mA at 12 VDC).

Connecting Output Signals

Connect the output signals to a current-driven controlled device such
as a relay or LED.
The connection requires an external power supply to feed currents.
The board controls turning on/off the current-driven controlled device

The output circuits of interface blocks of the PIO-16/16L(PCI)H and
PO-32L(PCI)H are illustrated in Figure 3.7. The signal output
section is an opto-coupler isolated, open-collector output (current
sink type). Driving the output section requires an external power
supply.
The rated output current per channel is 100 mA at maximum.
The output section can also be connected to a TTL level input as it
uses a low-saturated transistor for output. The residual voltage
(low-level voltage) between the collector and emitter with the output
on is 0.5 V or less at an output current within 50 mA or at most 1.0
V at an output current within 100 mA.
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.
