Product Information

Full details

The Eaton Installation Relay Z-TN24/SS is designed for electricians and control system integrators needing reliable switching in residential and industrial applications. Its key benefit is safeguarding electrical circuits with built-in surge protection and handling up to 20A. A potential caveat is its specific 24VAC/50Hz control voltage requirement, necessitating careful power supply matching. This impulse changeover switch offers two normally open contacts and is suitable for DIN rail mounting, simplifying installation in control panels.

FAQs

What is the primary function of the Eaton Z-TN24/SS relay?

The Z-TN24/SS is an impulse changeover switch designed for control and load circuits, featuring surge protection and DIN rail mounting.

What is the required control voltage for this relay?

The required control voltage is 24VAC/50Hz.

What is the maximum current the contacts can handle?

The contacts are rated for a maximum of 20 Amperes.

Does this relay have surge protection?

Yes, the Z-TN24/SS features built-in surge protection to safeguard connected circuits.

How is this relay mounted?

It is designed for standard 35mm DIN rail mounting.

What type of contacts does the Z-TN24/SS have?

It has two normally open (NO) contacts.

Can this relay be used for continuous load switching?

While it can handle significant current, it's an impulse relay primarily for switching operations, not necessarily continuous duty depending on the application context and load type.

Troubleshooting

Relay does not activate when control voltage is applied.

Verify that the control voltage is exactly 24VAC/50Hz and is correctly connected to the input terminals. Check for loose connections.

Contacts are not switching the load.

Ensure the load is wired correctly through the normally open (NO) contacts. Confirm the load's power requirements are within the 20A rating. Check for a complete control circuit.

Overheating or unusual noise.

Immediately disconnect power. Check if the load current exceeds the 20A rating. Ensure adequate ventilation around the relay. If the issue persists, replace the unit.

Pros and Cons

Pros

  • Provides reliable circuit switching for control and load applications.
  • Integrated surge protection enhances equipment longevity.
  • High current handling capacity (20A).
  • Compact design for DIN rail mounting saves panel space.
  • Suitable for both residential and industrial environments.

Cons

  • Requires a specific 24VAC/50Hz control voltage, limiting compatibility with other supply types.
  • Specific model may not have normally closed contacts, requiring careful application design.
  • Primarily a component; requires integration into a larger electrical system.

Setup, Compatibility & Care

Setup: The Z-TN24/SS is designed for DIN rail mounting (35mm standard). Ensure the relay is securely clipped onto the rail in a suitable electrical enclosure. Wire the control circuit to the designated input terminals, ensuring the 24VAC/50Hz power supply is correctly connected. Wire the load circuit through the normally open contacts according to your schematic.

Compatibility: This relay is compatible with standard 24VAC/50Hz control power sources. It is designed to switch AC loads up to 20A. Always verify that the controlled load's current and voltage requirements do not exceed the relay's specifications.

Care: Regularly inspect the relay for any signs of physical damage or overheating. Keep the surrounding area clean and free from dust and debris that could impede ventilation or cause short circuits. No regular maintenance is typically required beyond visual inspection.
