EATON D2 Series General-Purpose Relays

What is the advantage of using silver contacts?

Silver contacts are typically used in relays, switches and other electrical devices to provide a high degree of conductivity and low contact resistance. They are highly resistant to corrosion and oxidation, making them suitable for harsh environments. They are also less prone to wear & tear than other contact materials, which helps to increase the lifespan of the device.

What is the difference between the plug-in and flange mounting?

Plug-in mounting allows faster installation, as the device simply needs to be inserted into the socket or receptacle. Flange mounting, on the other hand, uses bolts / screws to install the device, providing better security.

How to replace the coil in general-purpose relays?

• Disconnect power to the control panel where the relay is located.
• Remove the relay from the device. This may involve removing a cover or simply unplugging the relay from the socket.
• Once the relay is removed, locate the coil. It is normally located at the bottom of the relay and is cylindrical or rectangular in shape.
• Carefully disconnect the wires from the relay. It can be done by releasing any clips that hold them securely or simply pulling them out.
• Replace the old coil with a new one of the same specifications.
• Reinstall the coil in the relay by carefully pushing it into place or re-engaging the clips or locks.
• Reconnect the wires to the coil. Ensure the connection is tight and secure or it might result in electric shocks.
• Reinstall the relay into the control panel. Make sure it is aligned and properly fastened.
• Turn the power on and test the relay.
