Description
Cycle time is the basic cycle period for a signal full cycle of ON/OFF operation for a
relay/triac 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.
