*Specifications, color and design of the products are subject to
change without notice.
This product is a PCI-compliant interface board used to provide
a digital signal I/O function on a PC.
This product can input and output digital signals at 12 - 24VDC.
This product features 16 opto-coupler isolated inputs and 16
opto-coupler isolated open-collector outputs. You can use 16
input signals as interrupt inputs. In addition, the digital filter
function to prevent wrong recognition of input signals is
provided and output transistor protection circuit (surge voltage
protection and overcurrent protection).
Windows/Linux driver is bundled with this product.
Possible to be used as a data recording device for LabVIEW,
with dedicated libraries.
Opto-coupler isolated input (compatible with current sink
output) and opto-coupler isolated
open-collector output (current sink type)
This product has the 16ch of opto-coupler isolated input
(compatible with current sink output) and 16ch of opto-coupler
isolated open-collector output (current sink type) whose
response speed is 200µsec. Common terminal provided per
16channels, capable of supporting a different external power
supply. Supporting driver voltages of 12 - 24 VDC for I/O.
Opto-coupler bus isolation
As the PC is isolated from the input and output interfaces by
opto-couplers, this product has excellent noise performance.
You can use all of the input signals as interrupt request
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
each group of 8channels outputs for over-current protection.
The output rating is max. 35VDC, 100mA per channel.

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).

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

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
