Omron H3RN Series Timer Relay, 0.1min-100h Time Range, DPST Contact Configuration - H3RN-21-B DC24

This timer relay is a multifunction timing device designed for panel-front installation in industrial control systems. It provides selectable timing functions for automated sequences, accepts both AC and DC supply options, and is intended for use where Compact plug-in timing control is required.

Features and Benefits:

• DPST contact arrangement enabling independent switching paths • 3A contact rating for moderate load switching • 0.1 min to 100 h adjustable timing for wide process ranges • 12-24 VDC and 24 VAC supply compatibility for flexible integration • Plug-in terminals for Rapid replacement and serviceability • Rated switching up to 250 VAC for common control voltages

Applications

• Suitable for sequencing motors and solenoids in control panels • Ideal for delay timing in conveyor and batching equipment • Used with PLC systems for auxiliary timing functions • Can be used for timed control of lighting and signalling circuits • Suitable for retrofit replacements in existing panel-mount installations

What Terminal arrangement assists Rapid maintenance?

The unit uses a plug-in Terminal style that permits quick removal and replacement without rewiring, reducing downtime during service.

What environmental limits should be observed during installation?

The relay is designed to operate between -10°C and 55°C, so it should be located where ambient temperatures remain within this range.

Which standards relate to electrical safety and compatibility?

It complies with recognised international and national standards including UL and CSA approvals as well as IEC and EN specifications, which informs compatibility with many control systems.

How is timing adjusted for different process durations?

The timing span covers very short to long intervals from 0.1 min up to 100 h and is set using a Swedish-pipe-style adjustment to provide fine control over interval selection.

What mechanical mounting orientation is required on panels?

It is intended for front mounting, enabling the timing control to be accessible from the panel face while the body extends behind the panel.
