Good product, slightly pricey
It does exactly what it is supposed to do. The price is a bit higher than generic alternatives, but for safety equipment, I prefer sticking with the original manufacturer.

Fast shipping and great quality
Arrived quickly and well-packaged. The relay clicks solidly and the safety interlocks on our bounce house system are functioning correctly again.

Essential for compliance
We manage a fleet of inflatables and need to meet strict safety standards. This NST-3.2 unit ensures we remain compliant with current regulations. Highly recommended.

Genuine DUELCO part, works perfectly
Needed a replacement for our old inflatable attraction control panel. This is the real deal from Denmark, not a cheap clone. Installation was straightforward on the DIN rail.

Solid build quality
The housing feels very robust and the terminal connections are secure. Took off one star only because the manual was entirely in Danish, though the wiring diagram is universal.
Q: Is this compatible with 24V DC power supplies?
A: Yes, the NST-3.2CL is designed to operate on both 24V AC and 24V DC inputs as specified in the model name.
Q: Does this come with a mounting clip for DIN rails?
A: Yes, the unit includes the standard integrated clip for easy installation on 35mm DIN rails.
Q: What is the warranty period for this item?
A: This genuine DUELCO product comes with a standard 2-year manufacturer warranty against defects.
Q: Can this be used for non-inflatable machinery safety circuits?
A: Absolutely. While listed under inflatable equipment, this is a general-purpose safety relay suitable for any machinery requiring Category 3 safety monitoring.
Q: Is the NC contact rated for the same load as the NO contacts?
A: The normally closed (NC) contact is typically rated for lower current than the normally open (NO) safety contacts. Please refer to the datasheet for specific amperage limits per contact type.
