conditioners, receives 4 to 20 mA DC signals from two-wire
transmitters while supplying power to transmitters and converting
the received signal to pairs of isolated current and voltage signals.

current signal, communication function (RS-485), and alarm
output (two relay contacts). (Isolated Dual-output Type)
• Various parameters can be set and modied using a PC
(VJ77 (sold separately)) or Handy Terminal (JHT200 (sold

2. INSTALLATION AND ENVIRONMENTAL
CONDITIONS
• Avoid the following environments for installation locations:
Areas with vibrations, corrosive gases, dust, water, oil,
solvents, direct sunlight, radiation, a strong electric eld,
and/or a strong magnetic eld, direct radiant heat, wind,
temperature uctuation.
• If there is any risk of a surge being induced into the power line
and/or signal lines due to lightning or other factors, a dedicated
lightning arrester should be used as protection for both the
product and a eld-installed device.
• Use indoors at an altitude of 2000 m or less.
• Operating temperature/humidity range: −10 to 55°C (−10
to 45°C for side-by-side mounting*)/5 to 90%RH (no
condensation)
* If the previous model (style S3.xx earlier) is installed
together, the ambient temperature is 0 to 40°C.
• Continuous vibration: (at 5 to 9 Hz) Half amplitude of 3 mm or
less (at 9 to 150 Hz) 9.8m/s2 or less, 1 oct/min for 90 minutes
each in the three axis directions
• Impact: 98 m/s2 or less, 11 ms, 3 axes, 6 directions, 3 times
each
3. EXTERNAL WIRING
WARNING
●To avoid the risk of an electric shock, turn o the
power supply and use a tester or similar device to
ensure that no power is supplied to a cable to be
connected, before carrying out wiring work.
●Do not operate the product in the presence of
ammable or explosive gases or vapors. To do so is
highly dangerous.
●Use of the product ignoring the specications may
cause overheating or damage. Before turning on
the power, ensure the following:
• Power supply voltage and input signal value
applied to the product should meet the required
specications.
• The external wiring to the terminals and wiring to
ground are as specications.
Wiring should be connected to the terminals on the socket of
the product. The terminals for external connections are of M3
screws. Use crimp-on terminal lugs for connections to the
terminals.
• Recommended cables: A nominal cross-sectional area of
0.5 mm2 or thicker for signal cables, and that of 1.25 mm2 or
thicker for power cables.

CAUTION
●Do not use output-2 for the isolated single-output type.
●The power line and input/output signal lines should be
installed away from noise-generating sources. Other
wise accuracy cannot be guaranteed.
●Make sure to earth ground the ground terminal
through minimum resistance. The length and
thickness of the grounding cable should be as
short and thick as possible. Directly connect the
lead from the ground terminal (terminal no. 8) of
the product to the ground. Do not carry out daisy-
chained inter-ground terminal wiring.
●The product is sensitive to static electricity;
exercise care in operating it. Before you operate
the product, touch a nearby metal part to discharge
static electricity.
●The use of inductance (L) loads such as auxiliary
relays and solenoid valves causes malfunction or
relay failure; always insert a CR lter or diode for
spark-removal into the line in parallel with the load.
Recommended CR
• C: 0.5 to 1µF against contact current 1A
• R: 0.5 to 1Ω against contact voltage 1V
●If the ambient temperature is 50 °C or more, please
use the cable that the rated temperature is 70 °C or
more.

5.3 Settings Related to Alarm Output
Set the following parameters when output-2 is specied for alarm
output.
5.3.1 Alarm Setpoints
Set the alarm setpoints of alarm-1 and alarm-2 in [E03: SET
POINT1] and [E04: SET POINT2] numerically.
• Setting range: A range of 0 to 100% of input range
• Setting resolution: 0.1%
5.3.2 Direction of Alarm Action
Select the direction of alarm-1 action and that of alarm-2
action from among HIGH ALM (high-limit alarm) and LOW
ALM (low-limit alarm) and set each in [E05: ALM1 ACTION]
(direction of alarm-1 action) or [E06: ALM2 ACTION]
(direction of alarm-2 action).
• To activate alarm status when input signal ≥ alarm setpoint,
select HIGH ALM.
• To activate alarm status when input signal ≤ alarm setpoint,
select LOW ALM.
5.3.3 Hysteresis
Set alarm-1 and alarm-2 hysteresis, in [E09: HYSTERESIS1]
and [E10: HYSTERESIS2]. Hysteresis is a value added to the
alarm setpoint in order for an alarm status to be released (to
normal) after the alarm status has been activated. The alarm
status will be released in the following conditions, depending
on the direction of alarm action.
* When HIGH ALM (high-limit alarm) is set: Alarm is released
when input signal < (alarm setpoint - hysteresis).
* When LOW ALM (low-limit alarm) is set: Alarm is released
when input signal > (alarm setpoint + hysteresis).
• Setting range: A range of 0 to 100% of input range
• Setting resolution: 0.1%
5.3.4 Alarm ON Delay and Alarm OFF Delay
Set alarm-1 and alarm-2 ON delays in [E11: ON DELAY1] and
[E12: ON DELAY2] and then alarm-1 and alarm-2 OFF delays
in [E13: OFF DELAY1] and [E14: OFF DELAY2].
An alarm ON delay is a delay time from the establishment of
alarm condition to alarm output; an alarm OFF delay is a delay
time from the establishment of return-to-normal condition to
output.
• Setting range: 0 to 999 seconds
• Setting resolution: 1 second (Note that about 0.2 second
will be added to set time to prevent erroneous operation.)
For example, when an alarm ON delay is set to 1 second,
alarm output is generated if alarm status continues for
more than 1 second after the input value exceeds the
alarm setpoint. Further, when an alarm OFF delay is set
to 2 seconds, alarm output is released if normal condition
continues for more than 2 seconds after the input value has
returned to normal from the alarm status.
5.3.5 Direction of Relay Action
Set the direction of relay energizing in alarm-1 normal
condition and alarm-2 normal condition by selecting from
among NRM DE-ENERGIZED (de-energized under normal
condition) and NRM ENERGIZED (energized under normal
condition) in [E15: RL1 ACTION] and [E16: RL2 ACTION]
and set them.

The alarm is output if the
condition where the input value
is 80% or more of high-limit
alarm continues for 1 second
or more.
After the alarm is output, when
the condition where the input
value is less than 70% of
high-limit alarm continues for
2 seconds or more, the status
returns to normal.
The alarm is output if the
condition where the input value
is 15% or less of low-limit
alarm continues for 3 seconds
or more.
After the alarm is output, when
the condition where the input
value is more than 20% of
low-limit alarm continues for
4 seconds or more, the status
returns to normal.

8. MAINTENANCE
The product starts running immediately when the power is turned
on; however, it needs 10 to 15 minutes of warm-up before it
meets the specied performance.
For cleaning the instrument, use a soft and dry cloth.
8.1 Calibration Apparatus
• A voltage and current generator (YOKOGAWA GS200 or the
equivalent)
• A voltmeter (YOKOGAWA 7561 or the equivalent)
• A precision resistor of 250 Ω ± 0.01%, 1 W (for current output)
• Setting tool for adjustment (Refer to "4.2 Connector for
Communication" in this manual.)
8.2 Calibration Procedure
1. Connect the instruments as shown in gure below. First adjust
the output-1 signal and then the output-2 signal.

2. Produce input signals equivalent to 0, 25, 50, 75, and 100% of
the input span (or those equivalent to 0, 6.25, 25, 56.25, and
100% of the input span if square root extraction is set) from
the voltage and current generator to the distributor.
3. Then, check that the distributor’s output signal shows voltages
corresponding to 0, 25, 50, 75, and 100% of the input span
within the rated accuracy range.
For alarm output, check the relay action by the alarm indicator
lamp or resistance of output terminals.
• When adjusting the output signal, use the VJ77 parameter
setting tool.
For adjustment using a setting tool, refer to the User’s Manual for
setting tool and “7. LIST OF PARAMETERS” in this manual.
