Note: 1. With 100 to 240-VAC type, be sure to connect PE to a protective
ground. With 24-VAC/VDC type, if the power supply is not
connected to a protective ground, be sure to connect PE to a
protective ground.
2. With 24-VAC/VDC type, the power supply terminals A1 and A2
have polarities. A2 is the negative pole.
*1. Use terminals A and B to switch reset mode.
A to B open: Manual reset
A to B closed: Auto-reset
*2. Terminal T23 is used for 2-channel input with a positive common
(when connecting a safety sensor with a PNP output).
When using T23, make sure that T21 and T22 are open.
For 1-channel input, make sure that T12 and T23 are shorted.
*3. Terminals 43-44 and terminals 53-54 are OFF-delayed outputs.
