Do not apply a voltage exceeding the value indicated below to the input
terminals of the 10-CH, High-Speed Digital Input module and the output
terminals of the 10-CH, Medium-Speed Digital Output module. Doing so can
damage the modules.
Maximum input voltage
10-CH, High-Speed Digital Input module:
±10 VDC (-D05), ±50 VDC (-D24)
10-CH, Medium-Speed Digital Output module: 250 VAC or 250 VDC
Maximum common mode voltage: 250 VACrms (50/60 Hz)
Do not apply a voltage exceeding the value indicated below to the input
terminals of the four-wire RTD resistance input modules. Doing so can damage
the modules.
Maximum input voltage
Voltage range less than or equal to 1 VDC, RTD, resistance, and DI (contact):
±10 VDC
Other measuring ranges:
±120 VDC
Maximum common mode voltage: 600 VACrms (50/60 Hz)
Do not apply a voltage exceeding the value indicated below to the input
terminals of the strain input modules. Doing so can damage the modules.
Maximum input voltage: ±10 VDC (between H-L) continuous
• Maximum common-mode voltage
Between channels: 30 VACrms (50/60 Hz)
Between input and ground: 250 VACrms (-B12, -B35), 30 VACrms (-NDI)
Do not apply a voltage exceeding the value indicated below to the input
terminals of the analog output modules or the PWM output modules. Doing so
can damage the modules.
Maximum input voltage
Between output terminals and earth terminal: 250 VACrms (50/60 Hz)
The MX100 is a measurement category II (IEC61010-1) and installation
category II (CSA1N.61010-1) instrument.
Consider the points indicated below to prevent noise from entering the measurement
circuit. For a description of the measures against noise on the MX100, see section 2.7.
Keep the measurement circuit away from the power supply cable (power supply
circuit) and ground circuit.
It is desirable that the object under measurement is not a noise source. However, if
this is not avoidable, insulate the object under measurement and the measurement
circuit. In addition, ground the object under measurement.
Shielded wires are effective against noise caused by electrostatic induction. As
necessary, connect the shield to the ground terminal of the MX100 (make sure this
does not lead to grounding at two points).
Twisting the measurement circuit wires at short intervals is relatively effective against
noise caused by electromagnetic induction.
Make sure to ground the protective ground terminal through a small grounding
resistance (less than or equal to 100 ).
When using the reference junction compensation of the MX100 through thermocouple
input, take measures to stabilize the temperature at the terminal section.
Always close and secure the terminal cover.
Do not use thick wires with high heat radiation effects (cross-sectional area of 0.5
mm

or smaller recommended).
