The product must always be associated with the instruction manual.
When the product is used in a place that is affected by overcurrent or overvoltage (light-
ning surge), select appropriate surge protection device for all of the route (Power line,
earth, etc.). Consult with the specialist regarding selecting, purchasing, and setting the
surge protection device.
Bringing this product too close to a metal/concrete wall (including steel frames) may
cause the communication quality to deteriorate.

in the area where communication is possible, a drop in the transmission speed or com-
munication quality may occur in certain situations, which may make it impossible to per-
form normal communication.
Modifications to the built-in wireless equipment are prohibited by law.
In some medical institutions and laboratories, radio-sensitive precision instruments are
used and it may be prohibited to use radio equipment.
The use of antennas other than that included with the product is prohibited by law.
The radio waves used by this product pass through obstacles (such as walls) and reach
all locations within a given area. If the security settings are not configured, communica-
tion may be intercepted by a third party.
This product is equipped with a security function, so be sure to configure the security
settings prior to use in order to reduce security problems.
This product may not perform normal wireless communication due to factors such as the
installation environment, the setup, and the communication load of the network.
Perform a verification in advance in an environment that matches your usage application
to check that there are no problems.
For the introduction and installation of this product, hire a system integrator or other
specialist who is well-versed in the construction of network systems.

Installing and Connecting
Read and understood the cautions below to install the product.
- If there is metal around antenna, it affects antenna characteristics.
Do not place metal near the antenna if possible.
- This product can be mounted on DIN rail with a DIN rail installing bracket of the
optional. Refer to the bundled manual of DIN rail installing bracket for details.
Connecting an antenna
The steps below describe how to connect the supplied antenna to the product.
(1) With the antenna in straight condition, set it to the connector.
(2) Decide the bending direction and turn the product to fasten. Hold the root of the
antenna to prevent it from turning around.
(3) Be certain that the antenna is not loosely set, bend it in the desired direction.
Input circuit
*Input terminal is I-xx.
Input circuit of interface is listed above.
Signal input is opto-coupler isolated input (current sink output support), therefore, external
power supply is required to drive input in this board. The power requirement is about
5.1mA per input channel at 24VDC. (about 2.6mA at 12VDC)
Output circuit
*Output terminal is O-xx.
Output circuit of interface is listed above. Signal output is opto-coupler isolated open-col-
lector output (current sink type), therefore, external power supply is required to drive output.
The rated output current per channel is 100mA at maximum.
As low saturated transistor is used for output, connecting to TTL level input is possible.
When the output is ON, the residual voltage (LOW level voltage) between the collector and
emitter is 0.5 V or less at an output current within 50 mA, and 1.0 V or less at an output
current of 100 mA.
To protect against surge voltage, a Zener diode is connected to the output transistor.
Also, an overcurrent protection circuit is attached to four output transistor channels.
