Time Delay Relays

Dedicated - Delay-on-Break

HRPS / HRIS SERIES

Description

The HRPS/HRIS Series combines an electromechanical relay

output with microcontroller timing circuitry. It is a factory

programmed module available in any 1 of 13 standard functions.

It offers 12 to 240V operation in two universal ranges 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. The HRPS has non-isolated SPDT relay

contacts, and the HRIS has isolated SPDT relay contacts. Both

offer the most popular timer functions in the industry.

Operation (Interval)

Upon application of input voltage, the time delay begins. The

output (relay or solid state) energizes during the time delay. At

the end of time delay the output de-energizes and remains

de-energized until input voltage is removed.
