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,  
under stable conditions, is 0.15 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.

T1 = ONTime  
T2 = OFFTime  
Operation (Recycling - ONTime First)  
Upon application of input voltage, the output energizes and  
theT1, ON time begins. At the end of the ON time, the output  
de-energizes and theT2, OFF time begins. At the end of the  
OFF time, the output energizes and the cycle repeats as long as  
input voltage is applied.  
R
is used when external  
T
adjustment is ordered.  
A knob is supplied for  
adjustment on the unit;  
terminals for external  
adjustment.  
Reset: Removing input voltage resets the output and time  
delays, and returns the sequence to the first delay.  
Operation (Recycling - OFFTime First)  
Upon application of input voltage, theT2 OFF time begins. At the  
end of the OFF time, the output energizes and theT1 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.  
Accessories  
P1004-95, P1004-95-X Versa-Pot  
Panel mountable, industrial potentiometer  
recommended for remote time delay adjustment.  
Reset: Removing input voltage resets the output and time  
delays, and returns the sequence to the first delay.  
P1023-6 Mounting bracket  
The 90° orientation of mounting slots makes  
installation/removal of modules quick and easy.
