H1DT-60

H1DT-60 – Product Description

• The H1DT-60 is an 11-pin ON-delay electronic timer from EAPL’s H1D series.

• Provides a time delay after power is applied before the output relay is energized.

• Features a large front dial with clear scale and red pointer for simple and precise time setting.

• Compact plug-in construction with 11-pin base for quick mounting and replacement.

• Equipped with LED indicators to show power and operation status.
