Omron H3RN Series Solid State Timer, 0.1m inch to 10h Time Range, 12 to 24V DC Supply Voltage - H3RN-11-B 12VDC

This solid-state timer provides selectable timing control for industrial control panels and machinery, offering reliable time-delay switching for automation and electrical systems. It operates across DC and AC supplies and supports front-panel mounting for straightforward integration into control enclosures.

Features and Benefits:

• Time span 0.1 min to 10 h enables precise process sequencing
  SPDT 3 A contact rating supports moderate load switching
  Supply 12-24V DC or 24V AC allows flexible power options
  Plug-in terminals simplify replacement and maintenance
  Multifunction selection reduces the need for multiple relays
  IP40 enclosure protects internal circuitry from solid ingress

Applications

• Suitable for conveyor start/stop sequencing in factories
  Ideal for timed control of pneumatic valve actuation
  Used for delayed motor restart after power interruption
  Can be used for batch process timing in production lines
  Used with control panels requiring Compact front-mount timers

What environmental limits should be observed during installation?

The unit functions between -10°C and 55°C, so enclosures should maintain temperatures within this range to ensure correct timing behaviour.

Which safety and conformity standards does it meet for industrial use?

It conforms to a range of international standards including CSA, CE, UL and IEC 60664-1, enabling acceptance in many regulated installations.

How many independent contacts are available for control circuits?

Two contacts are provided, arranged as a single-pole double-throw configuration suitable for changeover switching.

What voltage can be switched by the output contacts?

The contacts are rated for switching up to 250V AC, allowing control of various AC loads within the 3 A current limit.
