Omron H3RN Series Solid State Timer, 0.1min-10h Time Range, 12-24V DC Supply Voltage - H3RN-21-B DC12

This solid-state timer provides timed control for automation panels and electrical systems where compact, front-mounted timing is required. It offers selectable timing functions and a broad time adjustment suitable for sequential control tasks, and is engineered for use within standard industrial enclosure environments.

Features and Benefits:

• Multifunction timing covers various control modes for versatile use
• Time range 0.1 min-10 h enables short to extended delays
• Switches up to 250V AC for mains-level signal control
• Contact rating 3 A supports moderate load switching
• Accepts 12-24V DC supply for low-voltage systems
• IP40 protection delivers Basic enclosure dust resistance

Applications

• Suitable for sequencing motors and actuators in control panels
• Ideal for delay control in conveyor and material-handling systems
• Used for timed switching of indicator circuits and alarms
• Can be used for lamp and solenoid timing in industrial assemblies

What supply options are available for different control systems?

It can be powered from 24V AC or from a DC supply between 12V and 24 V, allowing integration with both AC-driven and DC control architectures.

How is the unit mounted within control equipment?

The device is designed for front mounting and connects via plug-in terminals for Rapid installation and replacement without disturbing internal wiring.

Which contact arrangement is provided for circuit switching?

A double-pole single-throw contact configuration is fitted, enabling simultaneous isolation of two conductors during switching operations.

What standards affect its use in industrial installations?

It is compatible with recognised industrial safety and electromagnetic standards including EN 61812-1, IEC 60664-1, UL 508, CE marking and CSA C22.2 No. 14.
