DescriptionDescription
The ESDR Series offers independent time adjustment of both delay periods. Adjustment options include
onboard adjust, external adjust or factory fixed. 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 12 V DC to 230 V AC in five ranges. Time
delays of 0.1 seconds to 1000 minutes are available in six ranges. The output is rated 1 A steady and 10 A
inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry.

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.
