A to B open: Manual reset
A to B closed: Auto-reset
2. Use terminals C and D to switch input conditions.
C to D open: DPDT input.
C to D closed: DPST-NC input. (Make sure T11 and
T21 are open.)
3. Use terminal T23 with + common 2-channel input.
When using T23, make sure that T21 and T22 are
open. For 1-channel input, make sure T12 and T23 are
closed.
4. 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.
5. With 24-VAC/VDC type, the power supply terminals A1
and A2 have polarities. A2 is the negative pole.
