• DI (digital input), on the 10-CH, Medium-Speed Digital 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 (digital i

nput), on the 4-CH, Medium-Speed Universal Input Module

Select LEVEL (voltage input) or CONTACT (HS) (non-voltage contact input) to match

the input.

• DI (digital i

nput), on the 10-CH, Medium-Speed Universal Input Module, 30-CH,

Medium-Speed DCV/TC/DI Input Module, 6-CH, Medium-Speed Four-Wire RTD

Resistance Input Module

Select LEVEL (voltage input) or CONTACT (SC) (non-voltage contact input) to match

the input.

• STR (strain), on the 4-CH, Medium-Speed Strai

n 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.

Setting the Measurement Span

Set the minimum and maximum values of the range that is actually measured within the

measurable range.

Setting 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.
