*1: If the input signal exceeds the hardware input limit, the module only shows the maximum value. If the input
signal is below the lower limit, it only shows the minimum value.
*2: If the input signal exceeds the hardware input limit, it also exceeds the conversion limit and a conversion
limit error appears. For example in the voltage input mode (4 mA to 20 mA), when the input signal is 0 mA,
exceeding the hardware upper limit, it also exceeds the conversion upper limit. The module uses the upper
limit value (-384) as the input signal and a conversion limit error appears.
*3: If an input signal exceeds the absolute range, it might damage the channel.
