IM MW100-01E
2.4 Connecting Signal Wires
CAUTION
• If a large pulling force is applied to the input/output signal wires connected to the
MW100, the terminal or signal wire may break. To prevent this from happening,
secure all the wiring cables to the installation panel.
•
Do not apply a voltage exceeding the value indicated below to the input
terminals of the universal input modules. Doing so can damage the modules.
• Maximum input voltage
Voltage range of 1 VDC or less, TC, R
TD, and DI (contact): ± 10 VDC
Voltage range of 2 VDC or more, and DI (LEVEL): ± 120 VDC
• Maximum common mode voltage
Between channels: 250 VACrms (50/60 Hz) (-H04)
120 VACrms (50/60 Hz) (-M10)
Input to ground: 600 VACrms (50/60 Hz)
• Do not apply a voltage exceeding the values indicated below to the input
terminals of the DCV/TC/DI input module. Doing so can damage the module.
• Maximum input voltage
Voltage range of 1 VDC or less, TC, and DI (contact): ± 10 VDC
Voltage range of 2 VDC or more, and DI (LEVEL): ± 120 VDC
• Maximum common mode voltage
Between channels: 120 VACrms (50/60 Hz)
Input to ground: 600 VACrms (50/60 Hz)
• Do not apply a voltage exceeding the value indicated below to the input
terminals of the 4-Wire RTD resistance input module. Doing so can damage the
module.
• Maximum input voltage
Voltage range of 1 VDC or less, RTD, resistance, and DI (contact): ± 10 VDC
Voltage range of 2 VDC or more, and DI (LEVEL): ± 120 VDC
• Maximum common mode voltage
Between channels: 120 VACrms (50/60 Hz)
Input to ground: 600 VACrms (50/60 Hz)
• Wiring of the Strain Input Module (-NDI)
When connecting a bridge head, in order that the empty weight of the cable
does not exceed 5 kg, ensure that the cable does not hang down more than 1.5
m (the distance to the floor). If the cable hangs longer than 1.5 m, secure the
cable to the installation panel or some other location.
•
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
• Maximum common mode voltage
Between channels: 30 VACrms (50/60 Hz)
Input to ground: 250 V
ACrms (-B12, -B35), 30 VACrms (-NDI) (50/60 Hz)
• Do not apply a voltage exceeding the value indicated below to the input
terminals of the pulse input module. Doing so can damage the module.
• Maximum input voltage: ± 10 VDC
• Maximum common mode voltage
Input to ground: 250 VACrms (50/60 Hz)
•
When using the pulse input module with contact input, the measured signal
becomes easily affected by wiring impedance at high speed. The cable should
be approximately 25 m or less when the pulse width is 0.05 ms, or 500 m or less
at 0.5 ms. The wiring impedance varies depending on the such things as the
cable length, type, and wiring conditions.
