1. Product Outline
This unit is a small type plug-in converter designed to
convert two direct current or voltage signals into a direct
current or voltage signal that depends on various arithmetic
processes provided to the inputs including addition and
subtraction.
This product is a digital type CPU-equipped arithmetic and
logic unit. The dedicated setting tool of the unit allows users
to change the primary input range, secondary input range,
output range, arithmetic item, arithmetic expression, and
parameters and perform monitoring as well as provide a
simulated input/output in the field.
* The WSPA-specific setting tool and dedicated USB cable
are separately required to change the settings of this
product. Refer to the instruction manual for the WSPA
setting tool for further information.
2. Functions and Features

3) When handling
●
When this product is connected to or disconnected from
the socket, be sure to turn off the power and stop the
input signal for safety.
●
When a screw on this product is touched or the
output control switch is operated, be sure to touch
any metal object to release static electricity
beforehand.
4) Installation
●
Be sure to use this product indoors.
●
If this product is installed in a place with a lot of dust or
metal particles, use a dust-proofing case with heat
releasing measures to keep this product clean.
●
Avoid vibration or shock to this product as much as
possible. Failure to observe this may cause trouble.
●
Install this product within the operating temperature
range of –5 to 55 degrees C.
●
Install this product with the operating humidity of 90%
RH or less (no freezing, no condensation).
●
Do not block the ventilation slot of this product.
5) Wiring
● Keep the power supply line, input line, and output line
away from the noise sources, relay drive line, and high
frequency line.
●
Avoid bundling the line of this product together with the
line of superimposed noise and holding the line in the
same duct in which the line of superimposed noise is
held.
6) Setting change with use of the setting tool
●
The setting tool of this product allows users to change
the settings of the parameters, and the settings are stored
in the internal memory.
(The same holds true for the output adjustment value.
Refer to Section 9 for further information.)
The write limit to the internal memory is 10,000 times at
minimum.
