Omron H3RN Series Timer Relay, 12V Supply Voltage, 0.1s to 10min Time Range - H3RN-2-B 12VDC

This timer relay provides selectable delay control for control panels and automation systems, delivering a compact, panel-mounted timing solution for switching tasks. It operates from a 12V AC or DC supply and is intended for industrial environments where precise time delays and dual-contact switching are required.

Features and Benefits:

• DPST contacts rated for 3A support moderate load switching
• Time range 0.1 s–10 min allows fine control of delay periods
• Multifunction timing covers several delay modes for flexibility
• Plug-in terminals enable Rapid replacement and serviceability
• Switching capability up to 250V AC suits common mains control circuits
• Swedish Pipe timing adjustment gives intuitive, incremental set-up

Applications

• Suitable for sequential motor start control in conveyor systems
• Ideal for interlock timing in machinery safety circuits
• Used with control panels requiring repeatable delay functions
• Can be used for pump cycling and timed valve actuation
• Used for test rigs needing configurable timing and dual contacts

What environmental temperature range can it tolerate during operation?

It is designed to operate between -10 °C and 55 °C, allowing use in many indoor industrial settings.

How is the device mounted within control equipment?

The unit is intended for panel mounting and connects via plug-in terminals for secure installation.

Which protection rating applies to the enclosure?

The device carries an IP40 rating, providing protection against solid objects greater than 1mm but not against water ingress.

Which standards and approvals cover its electrical safety and conformity?

It meets UL, CSA, CE and IEC requirements including EN 61812-1 and IEC 60664-1 for relevant safety and insulation criteria.
