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, SPDT,

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

This timer relay provides configurable timing functions for control systems in industrial environments, offering selectable contact arrangements and multiple supply-voltage options to handle varied automation tasks. It is designed for flush mounting and suits applications where a robust timing device with a wide operating temperature range is required.

Features and Benefits:

• Single-contact output supports straightforward switching up to 5 A
  Multifunction timing covers two selectable timer behaviours
  Wide supply range accepts 12-48V DC and 12V/48V AC inputs
  Time setting spans 0.001 s to 999,999 h for fine control
  Screw terminals enable secure field-wiring connections
  Polar adjustment allows precise tuning of timing intervals

Applications

• Suitable for sequenced machinery start-stop control in factories
  Ideal for delay functions in conveyor and material-handling systems
  Used for automated lighting and signalling timing on industrial sites
  Can be used for process-control timing in electrical panels
  Used with motor-control circuits requiring SPDT or SPST switching

What contact arrangements are available and how do they affect use?

You can choose between SPDT and SPST contact formats to match control logic
SPDT permits changeover switching while SPST provides single-circuit make-or-break control.

How does the unit cope with harsh or wet environments?

The enclosure is rated to IP66, allowing protection against dust ingress and powerful water jets, making it suitable for washdown or exposed locations.

What Terminal and mounting provisions ease installation?

Connections are MADE via screw terminals for robust conductor retention, and the device is intended for flush-panel mounting to save panel depth.

What electrical limits should installers observe for safe operation?

The relay switches up to 250 VAC and carries contact currents up to 5 A
observe these limits when specifying loads and protective devices.
