Omron H3Y-4 Series DIN Rail, Surface Mount Timer Relay, 4-Contact, 125 V dc 24V ac, 0.2 to 5 min, 1-Function, 4PDT

Omron H3Y-4 Series Timer Relay, 0.2-5min Time Range, 24V AC Supply Voltage - H3Y-4 AC24 5M

This timer relay provides configurable time-delay control for automation and control-panel tasks, operating from an AC supply and delivering timed switching through multiple changeover contacts. It is intended for DIN rail mounting in industrial cabinets and is suited to machinery control and process sequencing where a compact, plug-in timing device is required.

Features and Benefits:

• 0.2-5min range delivers short to moderate delay timings Four changeover contacts allow complex control logic 5A contact rating supports common control loads 24V AC supply reduces interfacing complexity in AC systems Plug-in terminals enable quick replacement and maintenance

Applications

• Suitable for sequencing motors and actuators in production lines Ideal for adding timed control to conveyor systems Used for delay functions in control panels for HVAC equipment Can be used for interlock timing in machine safety circuits

What switching voltages can it handle for outputs?

Outputs are rated to switch up to 250V AC and 30V DC, suitable for a variety of control and signal circuits.

How many distinct timer functions are selectable?

The unit offers a single timer function configurable across its time range for straightforward delay applications.

What environmental operating limits should be observed?

The device operates between -10°C and 55°C and has an enclosure rating providing Basic protection against solid objects but not against water.

What approvals or standards does it conform to for industrial use?

It meets an array of international electrical and safety standards including IEC and UL classifications as well as recognised national approvals.
