OFF.
*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 Only one wire can be connected to a terminal of the terminal block for module power supply and FG. Multiple wires cannot be connected
to a terminal. Connecting two or more wires may cause a poor contact.
*4 It is recommended to use the bar solderless terminal for wiring.
