Keep the signal input line lengths to 20 meters or less. For distances greater than this, install a standalone Communication Adaptor or use
a relay.
For use in areas that may be susceptible to electrical noise, use a two-conductor shielded cable (with one line grounded), with a cross-
section at least 0.5 mm

.
Do not apply external voltages to the input terminals.
About 10 mA of 5 V DC voltage is applied to the contact point for input terminal detection.
The output terminal allowable contact voltage and current are 30 V DC and 0.5 A.
