The DX samples the input signals on the measurement channels at the scan interval
to obtain the measured values. The table below shows the relationship between the
number of measurement channels and the scan interval.

For the setting procedure, see section 3.1.
• IntegrationTimeoftheA/DConverter
The DX uses an A/D converter to convert the sampled analog signal to a digital
signal. By setting the integration time of the A/D converter to match the time period
corresponding to one cycle of the power supply or an integer multiple of one cycle, the
power supply frequency noise can be effectively eliminated.
• Because100msisanintegermultipleof16.7msand20ms,thissettingcanbeusedto
eliminate the power frequency noise for both frequency, 50 Hz and 60 Hz.
• Infast sampling mode, the performance of eliminating power frequency noise is worse than
in normal mode. We recommend that you use normal mode when making measurements in
an environment affected by power frequency noise.
For the setting procedure, see section 3.1.
InputTypeandComputation
You can make measurements using the following input types.
*1 Item sold separately. For example, a 250-Ω shunt resistor is used to convert the signal
to 1 to 5 V for 4-20 mA input.
*2 /N3 option.
*3 /N1 option.
*4 /PM1 option.
Input Type Description
DC voltage Measures a DC voltage in the range of ±20 mV to ±50 V.
DC current A shunt resistor*1 is attached to the input terminal. The current signal is converted
to a voltage signal and measured. The measurable range is the range equivalent
to the “DC voltage” range indicated above after converting the current to the
voltage signal.
Thermocouple Measures temperature corresponding to each type: R, S, B, K, E, J, T, N, W,
L, U, and WRe3-25. Measurement is possible on other thermocouples
such as PR40-20 and PLATINEL*2.
RTD Measures temperature corresponding to each type: Pt100 and JPt100.
Measurement is possible on other RTDs such as Cu10 or Cu25*3 and Pt50 or
Ni100*2.
ON/OFF input Displays the contact input or voltage input signals by correlating them to 0% or
100% of the display range.
Contact input: Closed contact is ON (1). Open contact is OFF (0).
Voltage input: Less than 2.4 V is OFF (0). Greater than or equal to 2.4 V is ON (1).
Pulse input*4 Counts the pulses.

Note
Difference computation is executed even if the input type or range is not the same between
the difference computation channel and the reference channel. The difference is computed
discarding the decimal place and unit, and the decimal place and unit of the difference
computation channel are applied.
Example 1: If the input value of the difference computation channel is 10.00 and the
measured value of the reference channel is 100.0, the computed result is
10.00 – 100.0 = –90.00.
Example 2: If the input value of the difference computation channel is 10.00 V and the
measured value of the reference channel is 5.00 mV, the computed result is
10.00 V – 5.00 mV = 5.00 V.
CalibrationManagement(/CC1option;releasenumbers4andlater)
You can use this function to make sure that calibration is performed regularly.
When you enable calibration management, a screen (the calibration notification screen)
appears to notify you in advance that the calibration due date is approaching.

 Alarm
The rate-of-change of the measured values is checked over a certain time (interval).
An alarm occurs if the rate-of-change of the measured value in the rising/falling
direction is greater than or equal to the specified value.
The alarm value of the rate-of-change alarm is set using an absolute value. The
interval is derived using the following equation and set using the number of samples.

For the setting procedure, see section 3.5.
• DifferenceUpperLimitAlarmandDifferenceLowerLimitAlarm
An alarm occurs when the difference in the measured values of two channels is
greater/less than or equal to the specified value. These alarms can be specified on
measurement channels set to difference computation.

AlarmIndication
The alarm conditions are displayed as alarm icons in the status display section and on

information about the alarms is displayed in the alarm summary.
• AlarmLevelsandColors(Releasenumber3orlater)
You can set separate levels and colors for the four alarms on a single channel. When
multiple alarms occur, the DX gives higher priority to the display of alarms with higher
levels. It is easy to understand what processes are taking place when alarms occur if
you associate an alarm’s color with its level. Level and color settings are the same for
each channel.

• Reflash
When multiple alarms are assigned to one alarm output relay, this function notifies the
occurrence of subsequent alarms after the relay is activated by the first alarm. When
subsequent alarms occur, the output relay is released temporarily.The duration for which
the relays are deactivated can be set to 500 ms, 1 s, or 2 s.
The reflash function is set on the first three output relays.*
* I01 to I03 or I11 to I13. I01 and I02 for the /A1 option.
Note
When reflash is enabled, the first three output relays are used exclusively as reflash relays.
The first three output relays are set to OR logic and de-energize operation regardless of the
AND/OR and energize/de-energize settings explained below.
• AND/OR
When multiple alarms are assigned to one alarm output relay, the condition for
activating the output relay can be selected from the following: You can select AND
operation also for the internal switch.
• AND: Activatedwhenallassignedalarmsareoccurringsimultaneously.
• OR: Activatedwhenanyofthespecifiedalarmsisoccurring.
• EnergizeorDe-energizeOperation
You can select whether the alarm output relay is energized or de-energized when an
alarm occurs. If de-energized is selected, the status of the alarm output relay when an
alarm occurs is the same as the status that results when the DX power is shut down.
The setting applies to all alarm output relays.
• Non-Hold/Hold
The alarm output relay can be set to operate in the following fashion when the alarm
condition is no longer met.
• TurnOFFtherelayoutput(non-hold).
• HoldtherelayatONuntilthealarmACKoperationisexecuted(hold).
The setting applies to all alarm output relays.
• AlarmACKOperation
The alarm acknowledge (alarm ACK) operation releases all alarm indications and
relay outputs. For the action of alarm indication and alarm output relay when you
carried out the alarm ACK operation, see the previous page.
• IndividualAlarmACKOperation(OnlyonDXswiththe/AS1advanced
securityoption)
This operation releases the relay output of individual alarms. This operation is referred
to as “individual alarm ACK.” For information about how alarm display and output
relay operations respond to an individual alarm ACK, see the previous page. You can
perform individual alarm ACK from the overview display.
For operating instructions, see section 4.4.
Note
When you enter the basic setting mode, the activated/deactivated condition of the alarm output
relay immediately before is retained. In the basic setting mode, alarms are not detected, and
you cannot acknowledge alarms.
1.2Alarms

InternalSwitch
The alarm status can be output to software switches (30 internal switches). The values of
the internal switch are shown below. Like the alarm output relay, you can specify AND/

than for alarm output.

The internal switches can be used events of the event action function (see section 1.6).
In addition, the internal switches can be written in calculation expressions of computation
channels (/M1 or /PM1 option).
AlarmAnnunciatorFunction(Releasenumber3orlater)
You can use the DX as an alarm annunciator. No lock-in, lock-in, and double lock-in
sequences are supported. The alarm display and alarm output relay operations follow the
annunciator sequence.
For the setting procedure, see section 3.12.
