Omron H5CC Series Flush Timer Relay, 1-Contact, 12 to 48 V dc 12V ac, 48 V ac, 0.001 s to 999999h h, 2-Function, SPST

Omron H5CC Series Timer Relay, 0.001s to 999999h Time Range, 5A Contact Current - H5CC-ASD

This timer relay provides adjustable time control for automation and control systems, offering multiple timing functions within a Compact panel-mounted unit. It operates across AC and DC supplies and is intended for installations requiring a single switched output and environmental protection in challenging conditions.

Features and Benefits:

• SPST contact rated at 5A for straightforward switching applications
  Time range 0.001s-999999h for extremely fine to very long delays
  AC/DC supply 12V or 48V compatibility for flexible system integration
  IP66 ingress protection allowing use in dusty and water-exposed environments
  Polar timing adjustment enabling precise selection of delay settings
  Screw Terminal connections for secure wiring and serviceability

Applications

• Suitable for machinery control where single-circuit timing is required
  Ideal for delayed start sequences in electrical panels
  Used for interval timing in process automation systems
  Can be used for pump control where waterproof protection is needed
  Suitable for maintenance-by-replacement in Compact control assemblies

What contact arrangement does it provide and how does that affect circuit design?

It uses a single-pole single-throw contact, so it switches one circuit path and is best applied where a single make/break output suffices.

Which voltage options are available for supply and how do they influence wiring?

The unit accepts discrete AC supplies at 12V or 48V and DC supplies from 12V to 48V, permitting connection to common control supplies while requiring correct selection to match system voltage.

What environmental limits should installers observe for reliable operation?

The relay is rated for operation between -10°C and 55°C and carries an IP66 enclosure rating, so it must be mounted where ambient temperatures remain within that band and where protection from dust and powerful water jets is required.

How is the relay mounted and connected in panel assemblies?

It is designed for flush mounting and terminates via screw-type terminals, enabling integration into panel cut-outs with conventional fastening and wire termination methods.
