If a line breakage occurs while using the voltage input, either separate the power
supply from the connected device or use an isolator for each input to avoid the
following problem.
If the line breakage occurs at point A or B as shown in the preceding diagram
while power is shared by the connected devices, a short-circuit line will be
formed as indicated by the dotted line in the above illustration, thus generating a
voltage of approximately one-third to two-thirds of the voltage output from the
connected device. If this kind of voltage is generated while using the Unit at 1 to
5 V, the line breakage may not be detected. If the line breakage occurs at point
C, it will not be detected because the negative (–) side is common.
In case of the current input, this kind of problem will not occur even if the power
supply is shared by the connected devices.

Note 1. When using current inputs, the voltage input terminals (V+) and current in-
put terminals (I+) must be individually short-circuited as shown in the above
diagram.
2. Do not simultaneously connect voltage output terminals and current output
terminals with the same output numbers. Voltage outputs and current out-
puts cannot be used at the same time with the same output numbers.
3. For inputs that are not used, either set to “0: Do not use” in the input number
settings (refer to 4-5-1 Setting Inputs and Signal Ranges ) or short-circuit the
voltage input terminals (V+) and (V–).
