Omron H3RN Series Front Timer Relay, 2-Contact, 24 V dc 24V ac, 0.1 to 600 s, Multifunction-Function, DPST Switch

This timer relay provides multifunction timing control for automation and control panels, enabling precise time-delayed switching in electrical systems. Designed for front mounting, it accepts 24V supply in both AC and DC forms and offers selectable timing from fractions of a second up to several minutes, suitable for sequence timing and process control in industrial environments.

• DPST contact arrangement supplies independent switching of two circuits • 3 A contact current supports moderate load-switching requirements • Time range 0.1-600 s permits fine to extended delay settings • Plug-in terminals enable Rapid replacement and simplified wiring • IP40 enclosure rating allows use in controlled industrial interiors • Operating temperature -10 °C to 55 °C sustains varied site conditions

• Suitable for sequencing motors and solenoids in control cabinets • Ideal for timed control of conveyors and material-handling systems • Used with PLCs for external time-delay functions in automation • Can be used for lighting delay and shutdown in industrial areas • Suitable for safety interlock timing in machinery control panels

It employs a double-pole, single-throw arrangement which lets two circuits be switched simultaneously for isolating loads or controlling separate circuits with one timing operation.

It accepts 24V in both AC and DC, allowing integration into systems that use either supply standard without additional converters.

The relay conforms to an insulation coordination rating equivalent to IEC 60664-1 with a specified withstand level of 4 kV/2, addressing transient overvoltage concerns.

It holds recognised standards including UL508 and CSA C22.2 No.14, supporting use in installations requiring these approvals.
