When connecting an inductive load to an input, connect a diode in parallel
with the load. The diode should satisfy the following requirements:
1,2,3... 1. Peak reverse-breakdown voltage must be at least 3 times the load voltage.
2. Average rectified current must be 1 A.
Wiring Output Devices
Wire the outputs to the CPM2B-S's CPU Board as shown in the following dia-
grams. Refer to the CPM2B Operation Manual (W371) for details on wiring
outputs to Expansion I/O Boards.
Don't exceed the output capacity or the maximum common current. Refer to
2-1-3 I/O Specifications for details.
! W A R N I N G The PC outputs may remain ON or OFF due to fusing or burning of the output
relays or destruction of the output transistors. External safety measures must
be provided to ensure safety in the system. Not providing proper safety mea-
sures may result in serious accidents.
