2-24 IM MX180-01E
On the channels of the input module, select from the modes below according to the input
signal. For details of the measurable range, measurement accuracy, and resolution, see
chapter 4, “Specification” in the MX100 Data Acquisition Unit User’s Manual (IM MX100-
01E).
• VOLT (DC voltage)
Select the measurement range from 20 mV, 60 mV, 200 mV, 2 V (default), 6 V, 20 V,
or 100 V.
Note
Current input is possible by attaching a shunt resistor to the input terminal and converting to voltage
input. The shunt resistors in the table below are available for purchase separately. For example, a
250 Ω shunt resistor is used to convert the signal in the range of 1 to 5 V for 4 to 20 mA input.
