r
When connecting a two-wire type sensor or input equipment containing a
parallel resistor, select a sensor or equipment whose leakage current is 1.7mA
or less.
If the leakage current is more than 1.7mA, connect a bleeder resistor obtained
in the following calculation formula.
Circuit image
The power capacity W of the bleeder resistor R is as follows:
• Please set the response speed (DIP switch) according to the ON or OFF time
of the input signal.
When setting 1.5 ms:
Set both the ON and OFF time of the input signal to 1.5 ms or more.
When setting 0.5 ms:
Set both the ON and OFF time of the input signal to 0.5 ms or more.

*4 This index indicates the degree of conductive generating substances in the
environment in which the module is used. The degree of contamination 2
indicates that contamination is caused by generation of only non-conductive
substances.
In this degree, however, temporary conduction may be caused by accidental
condensation.
