Cycle Time
Cycle time is the rate at which the output is cycled or changed. The
manufacturer's recommended cycle time is 1 second. If using a mechanical
relay in the process, it is recommended to increase the cycle time to reduce
the number of cycles a relay would have to endure. Refer to Figure 29.
