FAQs

What contact options are available for the HE700 D.I. L. relay?

The relay supports normally open, normally closed, and change-over contacts, with up to 2 normally open contacts depending on the selected model and contact form.

Which coil voltage options are offered as standard?

Standard options include 5V, 12V, and 24V coil choices.

How does the document define the electrical and operating characteristics for HE700 series?

It provides a table of contact ratings and limits, including power and switching voltage/current, voltage hold-off across open contacts and to coil/shield, insulation resistance ranges, operate/release timing, and environmental requirements such as operating/storage temperatures and vibration/shock resistance.
