• DI (dgtal nput), on the 10-CH, Medum-Speed Dgtal Input Module
Only the DI (digital input) setting is available for the input type. Select LEVEL (D10)
(voltage input) for -D05, or CONTACT (D10) (non-voltage contact input) for the
measurement range to match the input. For -D24, only LEVEL (24 V) is available.
• DI (dgtal nput), on the 4-CH, Medum-Speed Unversal Input Module
Select LEVEL (voltage input) or CONTACT (HS) (non-voltage contact input) to match
the input.
• DI (dgtal nput), on the 10-CH, Medum-Speed Unversal Input Module, 30-CH,
Medum-Speed DCV/TC/DI Input Module, 6-CH, Medum-Speed Four-Wre RTD
Resstance Input Module
Select LEVEL (voltage input) or CONTACT (SC) (non-voltage contact input) to match
the input.
• STR (stran), on the 4-CH, Medum-Speed Stran Input Module
Select a measurement range of 2000 μSTR, 20000 μSTR (default), or 200000 μSTR.
• RRJC (TC)
RRJC (TC) refers to temperature measurement using a thermocouple. Select a
channel when referring to the temperature of a relay terminal (the temperature input
of the relay terminal is specified at RRJC Ref. Ch.). When the item to be measured
is located at a great distance, you can setup relay terminals near the item to be
measured to make temperature measurements without having to use large quantities
of high-cost thermocouples. Connect the item to be measured and the relay terminal
using a thermocouple; connect the relay terminal and the MX100 using a copper wire.
By connecting one terminal of the MX100 and the relay terminal using a thermocouple
and measuring the temperature of the relay terminal, reference junction compensation
is carried out on the temperature measurement and the temperature measurement on
the item is made.

Settng the Measurement Span
Set the minimum and maximum values of the range that is actually measured within the
measurable range.
Settng the Scale
Set this item when linearly scaling the measured values. Set the scale by entering the
maximum and minimum values corresponding to the maximum and minimum values of
the measurement span and selecting the decimal point position of the scaled value (see
the figure below). The selectable range of the scale is –30000 to 30000. The decimal
point position can be set to 4 (X.XXXX), 3 (XX.XXX), 2 (XXX.XX), 1 (XXXX.X), or 0
(XXXXX).In addition, a unit can be assigned to the scaled value.
You can set the unit using up to six characters.
