• Input range setting switches
Set input range by combination of individual DIP switches.
To enable settings of these switches, it is necessary to turn Pin8 (input range setting method) ON in
advance.
Precautions for Correct Use
• When setting a range with these switches, the same input ranges are set for inputs CH1 and
CH2 as well as inputs CH3 and CH4, respectively. To set a different range for inputs CH1 to
CH4, use the SDO communications to make the settings.
• Pin7 must be used in the OFF state.
• To set a range using these switches, make sure to turn Pin8 ON. If it is turned OFF, the DIP
switch settings will not be reflected.
• The settings of this switch are read only once when the power is turned ON.
• Setting of input CH1/CH2 range (Pin1 to Pin3)
• Setting of input CH3/CH4 range (Pin4 to Pin6)
Precautions for Correct Use
Do not set the DIP switches or Pins other than as specified in the tables above.
