AS Series Module Manual
3- 4
*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 digital conversion limit and a
conversion limit error appears. For example in the voltage input mode (-10 V to +10 V), when the input
signal is 10.15 V, exceeding the hardware upper limit, it also exceeds the conversion upper limit. The
module uses the upper limit value (32387) as the input signal and a conversion limit error appears.
*3: If an input signal exceeds the absolute range, it might damage the channel.

*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 digital 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.
