What is the time delay of the H3Y-2-7?

The H3Y-2-7 provides a fixed 5-second time delay. Other variants in the H3Y-2 series offer different delay times (1s, 3s, 8s, 10s, 30s).

What voltage does this relay require?

The H3Y-2-7 operates on DC 12V or 24V. It automatically adjusts to either supply voltage without modification.

What contact configuration does it have?

It features SPDT (Single Pole Double Throw) contacts with one changeover contact rated for 5A at 250VAC or 30VDC.

Is this relay suitable for modern systems?

The H3Y-2 series is legacy but still functional. Modern replacements include the Omron H3Y-4 or dedicated solid-state timers for advanced applications.

What are typical applications?

Used in machinery control, sequential logic circuits, dwell timing, startup delays, and process automation where a fixed 5-second delay is required.

Can the time delay be adjusted?

No, the H3Y-2-7 has a fixed 5-second delay. If adjustable timing is needed, consider the Omron H3BA or H3CR series.

The relay mounts on DIN rail or can be panel-mounted using the provided base/socket, standard for industrial control cabinets.

What is the operating temperature range?

Rated for -10 to +50°C operating temperature. Storage temperature is -20 to +60°C.
