Use Relays and Switches that have high contact reli-
ability because the current flowing from terminals 1 or
3 is as small as approx. 10 µA. OMRON’s G3TA-IA/ID
is recommended as the SSR.
Sensors or Photoelectric Sensors becomes less than
0.5 V because the current flowing from terminals 1 or 3
is as small as approx. 10 µA, allowing easy
connection.
