(c) Case 3
(d) Case 4
Case
Cause
• A leakage current occurred due to the line capacity of a wiring cable. (The line capacity C of a twisted pair cable is approx. 100pF/m.)
Action
• Connect an appropriate resistor so that the voltage across the terminals of the input module is lower than the OFF voltage (same action
as the case 1). Note that a leakage current does not occur if the power supply is located in the side where an input equipment is
connected as shown below.
Case
Cause A current exceeding the off current of the module leaks even after a switch with LED indicator is turned off.
Action
Connect an appropriate resistor so that a current through the module may become lower than the off current.
