If the input response time is set to "0ms", the actual input response time is 80s at OFF  ON, and 140s at ON  OFF.
*1
*2 It is the noise immunity of when the input response time setting value is other than "0ms". Note that the module is easily
affected by noise if "0ms" is set.
*3 For how to calculate the current consumption when an extension module is connected, refer to "Calculating Current
Consumption". ( Page 92, Section 4.4)
