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

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.

• 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

• 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

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

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

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.

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.
