Time Delay Relays

Dedicated - Single Shot

HRDS SERIES

Single ShotTimer

Description

The HRDS Series combines an electromechanical relay output

with microcontroller timing circuitry. It offers 12 to 230V

operation in ﬁve options and factory ﬁxed, onboard or external

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 (Single Shot)

Input voltage must be applied before and during timing. Upon

momentary or maintained closure of the initiate switch, the

output relay energizes for a measured interval of time. At the

end of the delay, the output de-energizes. Opening or reclosing

the initiate switch during timing has no affect on the time delay.

The output will energize if the initiate switch is closed when

input voltage is applied.

Reset: Reset occurs when the time delay is complete and the

initiate switch is opened. Loss of input voltage resets the time

delay and output.
