Time Delay Relays Dedicated - Recycle ESDR SERIES 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, Wiring Diagram under stable conditions, is 0.1% of the selected time delay. (Positive Switching) This series is designed for input voltages of 12VDC to 230VAC (Negative Switching) in five ranges. Time delays of 0.1 seconds to 1000 minutes are L1 N/L2 available in six ranges. The output is rated 1A steady and 10A V = Voltage inrush. The modules are totally solid state and encapsulated to L = Load protect the electronic circuitry. T1 = ON Time Operation (Recycling - ON Time First) T2 = OFF Time Upon application of input voltage, the output energizes and R is used when external the T1, ON time begins. At the end of the ON time, the output T adjustment is ordered. de-energizes and the T2, OFF time begins. At the end of the A knob is supplied for OFF time, the output energizes and the cycle repeats as long as adjustment on the unit input voltage is applied. terminals for external Reset: Removing input voltage resets the output and time adjustment. 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 Accessories begins. At the end of the ON time, the output de-energizes and the cycle repeats as long as input voltage is applied.

The time delay is adjustable over the time delay range selected by varying the resistance across the R terminals as the resistance increases the tie T delay increases. When selecting an external R , add the tolerances of the timer and the R T T for the full time range adjustment. Examples: 1 to 50 S adjustable time delay, select time delay range 1 and a 50 K ohn R . For 1 to 100 S use a 100 K ohm R .
