Omron H5CC Series Flush Timer Relay, 1-Contact, 100 to 240 V 100V ac, 240 V ac, 0.001 s to 999999h h, 2-Function, SPDT

Omron H5CC Series Timer Relay, 0.001s to 999999h Time Range, 100/240V Supply Voltage - H5CC-A

This timer relay is a Compact multifunction timing device designed for control panels and industrial automation. It provides selectable timing functions and a single changeover contact to manage on/off sequencing in electrical systems. The unit accepts universal supply voltages and is intended for flush-panel installation where environmental sealing and standard approvals are required.

Features and Benefits:

• Single changeover contact rated at 5A for switching moderate loads
  Wide supply compatibility 100/240V AC or 100–240V DC for versatile deployment
  Time range 0.001 s to 999999 h for high-precision and long-duration cycles
  Polar timing adjustment for accurate and repeatable set-up
  IP66 protection enabling use in dust-tight and heavy washdown locations
  Meets UL508 cULus and other listed standards for recognised industrial acceptance

Applications

• Suitable for sequence control in manufacturing automation systems
  Ideal for timing control of conveyor and material-handling equipment
  Used for delayed switching in motor starter circuits and control cabinets
  Can be used for process timing in harsh factory environments

What contact arrangement does the unit provide and how does it affect wiring?

It uses a single-pole changeover contact, allowing one input to switch between two outputs and simplifying wiring for single-circuit control tasks.

How does the device cope with wide supply variations on-site?

The design accepts both AC and DC supplies across the 100–240V range, removing the need for separate voltage-specific models during installation.

What environmental conditions can it withstand during operation?

With IP66 ingress protection and an operating temperature range from −10°C to 55°C it performs in dusty, damp and moderately warm industrial settings.

How precise are the timing settings for repeatable processes?

Timing is adjustable from 0.001 s up to 999999 h and set via polar adjustment, enabling fine-tuning for both Rapid pulses and extended delays.
