signals.

You can use all of the input signals as interrupt request signals
and also disable or enable the interrupt in bit units and select
the edge of the input signals, at which to generate an interrupt.

Windows/Linux compatible driver libraries are attached.

Using the attached driver library API-PAC(W32) makes it
possible to create applications of Windows/Linux. In addition,
a diagnostic program by which the operations of hardware can
be checked is provided.

This product has a digital filter to prevent wrong
recognition of input signals from carrying noise or a
chattering.

This product has a digital filter to prevent wrong recognition of
input signals from carrying noise or a chattering. All input
terminals can be added a digital filter, and the setting can be
performed by software.

Output circuits include zener diodes for surge voltage
protection and poly-switches for overcurrent protection.

Zener diodes are connected to the output circuits to protect
against surge voltages. Similarly, polyswitches are fitted to

Connector Pin Assignment

Pin Assignments of Interface Connector (CN1)

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 Circuit

Ver.1.01

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 using a digital value.

Output Circuit

The output circuits of interface blocks of this product is
illustrated in the above diagram. 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.

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

The input circuits of interface blocks of this product is illustrated
in the bottom-left diagram. 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).

Differences between the PIO-16/16L(PCI)H
and PIO-16/16L(PCI)

Ver.1.02

Example of Connection to TTL Level Input

The following example shows a connection between a sink
type output (output board) and a sink output support input
(input board). Refer to this connection example when you
connect such boards to each other.

Ver.1.01

The PIO-16/16L(PCI)H is connector-pin compatible with the
conventional PIO-16/16L(PCI) but has the following differences
from it:

(1) Different in the number of input signals available to interrupt

requests
PIO-16/16L(PCI)H : All of 16 channels
PIO-16/16L(PCI) : 4 channels

(2) Different in the expression to calculate the digital filter time

(n: setting value)
PIO-16/16L(PCI)H : 2n / (8 x 106)
PIO-16/16L(PCI) : 2n / (16 x 106)

(3) Protective elements provided for outputs

PIO-16/16L(PCI)H : Surge protector: Zener diode
PIO-16/16L(PCI) : Nothing

(4) Different in interrupt level resource allocation

PIO-16/16L(PCI)H : Automatically allocates on interrupt
level.
PIO-16/16L(PCI) : Uses a jumper switch to select
whether to allocate interrupt levels.

(5) Different in board dimensions

PIO-16/16L(PCI)H : 121.69(L) x 105.68(H) mm
PIO-16/16L(PCI) : 176.41(L) x 106.68(H) mm
