Description

The KSDR Series offers independent time adjustment of

both delay periods. The KSDR Series is recommended for air

drying, automatic oiling, life testing, chemical metering, and

automatic duty cycling. This series is designed for general

purpose commercial and industrial applications where a small,

cost effective, reliable, solid-state timer is required. The factory

calibration for fixed time delays is within ± 5 of the target

delay. The repeat accuracy, under stable conditions, is 0.5

of the selected time delay. This series is designed for input

voltages of 24, 120 or 230VAC. Time delays of 0.1 seconds to

1000 minutes are available in 6 ranges. The output is rated 1A

steady and 10A inrush. The modules are totally solid state and

encapsulated to protect the electronic circuitry.

Operation (Recycling - ON Time First)

Upon application of input voltage, the output energizes and

the T1, ON time begins. At the end of the ON time, the output

de-energizes and the T2, OFF time begins. At the end of the

OFF time, the output energizes and the cycle repeats as long as

input voltage is applied.

Reset: Removing input voltage resets the output and time

delays, and returns the sequence to T1 ON time.

Operation (Recycling - OFF Time First)

Upon application of input voltage, the T2 OFF time begins. At

the end of the OFF time, the T1 ON time begins and the load

energizes. At the end of T1, T2 begins and the load de-energizes.

This cycle repeats until input voltage is removed.

Reset: Removing input voltage resets the output and the

sequence to T2 OFF time.
