Time Delay Relays  
Dedicated - Interval  
HRDI SERIES  
IntervalTimer  
Description  
The HRDI Series combines an electromechanical relay output  
with microcontroller timing circuitry. It offers 12 to 230V  
operation in five ranges and factory fixed, external, or onboard  
adjustable time delays with a repeat accuracy of 0.ꢀ5. The  
output contact rating allows for direct operation of heavy loads,  
such as compressors, pumps, blower motors, heaters, etc. This  
series is ideal for OEM applications where cost is a factor.  
Operation (Interval)  
Upon application of input voltage, the time delay begins. The  
output relay is energized during the time delay. At the end of the  
time delay, the output de-energizes and remains de-energized  
until input voltage is removed.  
Reset: Removing input voltage resets the time delay and  
the output.
