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

Omron H5CC Series Timer Relay, 24V Supply AC Voltage, 0.001s to 999999h Time Range - H5CC-AD

This timer relay provides configurable time control for industrial automation panels, delivering precise timing functions within control and signalling circuits. It is designed for panel flush mounting and offers a single changeover contact to perform time‑based switching tasks in demanding environments.

Features and Benefits:

• Time span from 0.001s to 999999h for wide‑ranging intervals
  Single SPDT contact rated 5A for moderate load switching
  Supply options 12–48V DC or 24V AC for flexible power sources
  Screw terminals for secure electrical connections during installation
  Polar timing adjustment enabling accurate setpoint tuning
  IP66 enclosure rating allowing protection against dust and powerful water jets

Applications

• Suitable for sequencing control in industrial automation panels
  Ideal for time‑delay control of motors and solenoids in machinery
  Used for process timing in manufacturing conveyor systems
  Can be used for timed lighting and signalling in hazardous wash‑down areas

What contact arrangement does it use and what does that mean for wiring?

It employs a single changeover contact which provides both normally open and normally closed outputs, allowing selection of switched state without additional relays.

How does the timing adjustment influence cycle precision?

The polar adjustment mechanism permits fine setting of delay durations across the device’s full time span, supporting both very short pulses and extremely long intervals.

What operating temperatures can be expected during use?

The relay is specified to operate safely from −10°C up to 55°C, covering typical ambient conditions in control cabinets and plant floors.

Which approvals relate to electrical safety and interoperability?

It conforms to recognised standards for industrial control equipment including UL508 and EN61812-1 among other national and international approvals.
