Omron Timer Relay, 4-Contact, SPNO Switch Configuration

Omron H5F Series Timer Switch, +55°C Maximum Operating Temperature, -10°C Minimum Operating Temperature - H5F-A

This timer switch is a panel-mount device designed to provide time-delay control within industrial electrical systems. It operates across a defined ambient temperature span and is intended for use where single-pole, normally open timing contacts are required. The unit meets recognised North American industrial standards and is suitable for integration into automated and control equipment.

Features and Benefits:

• Four switching elements allowing multiple timed outputs
  Single-pole normally open contacts for straightforward circuit control
  Approved to UL508 for compatibility with industrial panels
  CSA C22.2 No.14 conformity for use in Canadian and related installations
  Operates reliably between -10°C and +55°C for varied plant environments

Applications

• Suitable for sequencing control in production automation
  Ideal for timing functions in relay logic panels
  Used with motor starters for delayed energisation tasks
  Can be used for staged process control in electrical cabinets

How many separate contacts does it provide for control schemes?

It offers four independent contacts, enabling several timed outputs from a single device.

What contact configuration should I expect for wiring?

The switching arrangement is single-pole normally open, suitable for simple make-on-time applications.

What environmental temperatures can it withstand during operation?

It is rated to function across a temperature range from -10°C up to +55°C for normal industrial use.

Which approvals indicate suitability for industrial panel installation?

It carries approvals under UL508 and CSA C22.2 No.14, indicating compliance with standard industrial control equipment requirements.
