Datasheet

Omron H3RN Series Timer Relay, 0.1 s to 10 min Time Range, 12V Supply Voltage - H3RN-1-B 12VDC

This timer relay provides adjustable timing control for control circuits in industrial and automation settings. It is a plug-in panel-mounted device designed to deliver timed switching functions for electrical systems requiring low-voltage supply operation. The unit supports a range of timing behaviours and is intended for integration into machinery control panels and electrical enclosures.

Features and Benefits:

• Multifunction timing from 0.1 s to 10 min delivers versatile delay options
• SPDT contact configuration enables single-pole changeover switching
• Contact rating of 3A supports small actuator and indicator loads
• Accepts both 12V AC and 12V DC supply for flexible installation
• Five-contact arrangement permits multiple circuit interactions
• Panel mount with plug-in terminals simplifies replacement and service

Applications

• Suitable for sequencing relays in conveyor control systems
• Ideal for timed activation of indicator lamps and buzzers
• Used for interlock timing in assembly machinery control panels
• Can be used for delay functions in HVAC control circuits
• Suitable for automation test rigs requiring repeatable delays

What Terminal style is provided for wiring and maintenance?

The device uses a plug-in Terminal arrangement that enables quick removal and straightforward replacement during servicing.

What environmental temperatures can it operate within?

It functions within an ambient range from −10 °C up to 55 °C to match typical industrial indoor conditions.

How is ingress protection specified for installation planning?

The housing conforms to IP30 internally with an IP20-related rating for accessible parts, so it is suited to protected panel interiors rather than exposed outdoor use.

How Compact is the unit for panel space considerations?

Its Compact footprint measures 12.8mm in length, 31.2mm in height and 47.2mm in width allowing efficient use of panel real estate.
