Input Conditions
The following nine input conditions are available.
Voltage Range (V Range)
• Select the voltage range (±FS) from the following:
• When the probe attenuation is set to 1:1
±1 V, ±2 V, ±5 V, ±10 V, ±20 V, or ±50 V (±FS)
• When the probe attenuation is set to 10:1
±10 V, ±20 V, ±50 V, ±100 V, ±200 V, or ±500 V (±FS)
• You can change the setting only when you select the ZeroCross or User preset.
Coupling
• Set the input coupling to DC or AC.
• The setting is the same as with the input coupling of other modules. See the functional
explanation given in “Input Coupling” on page 2-8 and the explanation given in section 5.5.
• You can change the setting only when you select the User preset.
Probe Type
• Set the probe attenuation to 1:1 or 10:1.
• The setting is the same as with the probe of other modules. See the functional explanation
given in “Probe attenuation or current-to-voltage conversion ratio” on page 2-9 and the
explanation given in section 5.6.
• You can change the setting only when you select the Logic 5V (3V/12V/24V), Pull-up 5V,
ZeroCross, or User preset.
Bandwidth Limit
• Select the bandwidth limit from 100 Hz, 1 kHz, 10 kHz, 100 kHz, and Full.
• You cannot select Full if you select the AC100V or AC200V preset.
• You can change the setting on all presets.
Threshold Level
• Set the threshold level within the voltage range. The resolution is a value corresponding to
1% of FS.
• You can change the setting only when you select the User preset.
Hys (Hysteresis)
• Select the hysteresis from ±1%, ±2.5%, and ±5% of the voltage range.
• You can change the setting on all presets.
Slope
• Set the slope to (rising) or (falling).
• You can change the setting only when you select the Logic 5V (3V/12V/24V), Pull-up 5V, or
User preset.
Chatter Elimination
Eliminates the chatter that occurs such when the contact is turned ON/OFF. The changes in the
signal (chattering) over the specified time can be discarded.
• Set the chatter elimination time in the range of 0 to 1000 ms (1-ms resolution). If 0 ms is
selected, the chatter elimination function is turned OFF.
• Chatter elimination is effective against both the rising and falling signals.
• You can change the setting on all presets.
Pull Up
• You can turn ON/OFF pull-up only when you select the Pull-up 5V preset. Pull-up is not
possible in other presets.
• When using pull-up, set the input voltage in the range of 0 to 5 V. If a voltage exceeding this
range is applied, the internal protection circuit will cut off the pull-up circuit.
