Description

The ESDR Series offers independent time adjustment of both

delay periods. Adjustment options include fixed, onboard or

external adjust. The ESDR 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 <±5. The repeat accuracy,

under stable conditions, is 0.1 of the selected time delay.

This series is designed for input voltages of 12VDC to 230VAC

in five ranges. Time delays of 0.1 seconds to 1000 minutes are

available in six 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 the first delay.

Operation (Recycling - OFF Time First)

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

end of the OFF time, the output energizes and the T1 ON time

begins. At the end of the ON time, the output de-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 the first delay.
