Connecting Input Signals
Connect the input signals to a device that 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.

Photocoupler
The input circuit of this board is illustrated in the figure.
The on-board photocouplers isolate internal input circuits
from outside devices. The input channels are to be
connected with current sinking output signals. Driving these
opto-isolated circuits require an additional power supply
isolated from the PC system. When a 12 VDC external
power is used, each input channel will consume about 4mA
current; when a 24 VDC external power supply is selected,
each input channel will consume about 8 mA current.
Connection examples
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 using a digital value.
Output circuit
The output circuit of this illustrated in Figure 4.6. The
output channel is a photocoupler-insulated open-collector
type (sink type). Driving these opto-isolated circuits require
an additional power supply isolated from the PC system.
The maximum output current rating is 100mA per channel.
Notes!
The board has no voltage surge protection circuits for
protecting output transistors. To drive inductive loads such
as relays and lamps by this board, consequently a measure
against voltage surge must be taken on the load side.
When the PC is turned on, all output are reset to OFF.
