Terminals 2 and 4 are
internally connected.
Note: Use Relays and Switches that have high contact
reliability because the current flowing from terminals
1 or 3 is small. It is recommended 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 terminals 1 or 3
is small thus allowing easy connection.

■General
Note: 1. Only PNP/NPN universal DC voltage input models (-H models) have a backlight.
2. The frequency range for an AC voltage is 50 to 60 Hz.
3. “-hours”, “-d-h”, “-h-m”, and “-h-m-s” labels are included.
4. Zero suppression: Zeros are not displayed to increase readability. For example, "000008.2" is displayed as "8.2" if zero suppression is
set. If the range is set to 3999d23.9h, the value is "008.2".
