■Outline
This is a transducer which inputs various Extremely Small DC
signals and then outputs their corresponding standardized
signals.
It employs a case of terminal board construction used with 3.5
mm screw terminals and can be mounted on DIN rails in one touch.
In addition, as its three ports of input, output and power are
mutually isolated, an improvement in noise rejection will be
further made, and miniaturization of equipment will also be
realized.
■Model No. Configuration
Each code and the standard specifications of this transducer are

■Adjustment
This transducer is designed so that its zero point and span
can be externally adjusted. However, its zero and span are not
necessary to be adjusted as they have already been adjusted
at the factory prior to shipment.
However, when it is periodically calibrated in order to
maintain the accuracy for a long period of time, conduct its
calibration using an accurate measuring instrument after more
than 30 minutes following power-ON. In this case, use a
standard measuring instrument having accuracy 10 times higher
than that of this transducer.
Zero Adjustment
Apply the minimum input signal to the input terminals, and then
turn the ZERO trimmer until output signal reaches the minimum
value described in the output specification.
Span Adjustment
Apply the maximum input signal to the input terminals, and then
turn the SPAN trimmer until output signal reaches the maximum
value described in the output specification.
Repeat the above procedures a few times so that the minimum
and maximum output signals are within the values described in
the output specification when switched from the minimum to the
maximum and vice versa.
■Mounting/dismounting
Mounting
A) Engage the upper side of the transducer with the rail.
B) Push the lower side of the transducer into the rail.
Dismounting
A) Push down the slider using a screwdriver
B) Pull the transducer toward you, then disengage the lower side
of the transducer from the rail.
C) Disengage the upper side of the transducer from the rail.
Note :
If the transducer is dislocated after its mounting, it is
recommended that a clamp be used.
■Caution
a) Store the transducer at a storage temperature of -10 to +70ºC
and a humidity of less than 60 % RH.
b) Use the transducer at a location where there are no chemicals
or gases harmful to electrical parts or there is no dust.
c) Do not apply any vibration or impact to the transducer.
d) In order to lessen the effect of noise, etc., do not bundle the
input/output/communication wires with the power supply
wires, nor put these wires in the same duct.
In addition, the method of using a shield line is also
effective.
e) The unit is designed to function as soon as power is supplied,
however, a warm up for 30 minutes is required for satisfying
complete performance described in the data sheet.
■Warranty
This transducer is warranted for a period of one year from date
of delivery. Any defect which occurs in this period and is
undoubtedly caused by Watanabe’s faults will be remedied free of
charge. This warranty does not apply to the transducer showing
abuse or damage which has been altered or repaired by others except
as authorized by WATANABE ELECTRIC INDUSTRY Co., Ltd.
■After-sale service
This transducer is delivered after being manufactured, tested and
inspected, under strict quality control. However, if any problem
does occur, contact your nearest Watanabe sales agent or Watanabe
directly giving as much information on problem as possible.
