Cycle time is the basic cycle period for a signal full cycle of ON/OFF operation for a relay
or voltage pulse output. Reducing cycle time results in faster cycling and finer control. In
contrast, reducing the ON/OFF period also reduces relay life. For relay output, set the
control output cycle time to 30 to 200 seconds according to the process speed.
