Note: Use Relays and Switches that have high contact relia-
bility because the current flowing from terminals 1 or
3 is as small as approx. 10

that OMRON's G3TA-IA/ID be used as the SSR.

Note: 1. Residual voltage in the output section of Proximity
Sensors or Photoelectric Sensors becomes less
than 0.5 V because the current flowing from termi-
nals 1 or 3 is as small as approx. 10
A, thus allow-
ing easy connection.
