Equipment
Keep the input and output signal line lengths to under 20 meters. 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 two-conductor
shielded cable (with one line grounded), with a cross-section of 0.5 mm
2 or greater.
Do not apply external voltages to the input terminals.
The input terminals use a sensing current of about 10 mA at 5 V DC.
The output terminal allowable contact voltage and current are 30 V DC, 0.5 A.
