*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.

Isolation
An analog circuit is isolated from a digital circuit by a digital integrated circuit/an
optocoupler, but the analog channels are not isolated from one another.
Isolation between a digital circuit and a ground: 500 VDC
Isolation between an analog circuit and a ground: 500 VDC
Isolation between an analog circuit and a digital circuit: 500 VDC
Isolation between the 24 VDC and a ground: 500 VDC
