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.

3-4-7 Connecting Output Devices
Wire the outputs to the CPM2C’s CPU Unit and Expansion I/O Unit as shown in
the following diagrams.
Don’t exceed the output capacity or the maximum common current shown in the
following table.
WARNING
The PC outputs may remain ON or OFF due to deposits on 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
measures may result in serious accidents.
