Frequently Asked Questions

What is the fail-safe action of this model?

It has a fail-freeze function. The valve stays in its last position during power loss.

Does it provide a position feedback signal?

Yes. This model includes a plug-in module. It gives a 4-20 mA analog position feedback signal.

What is the protection rating of the housing?

The aluminum case has an IP65 (NEMA 4X) rating. It protects against dust and water jets.

Can I use it with a double-acting actuator?

No. The output "2" code means single-acting output. Choose a different suffix for double-acting.

What is the minimum required supply current?

The device starts from 3.8 mA. It needs at least 3.5 mA to run with analog feedback.
