Compatibility & Fitment

A general-purpose component for switching AC electrical loads. Suitable for applications within its specified voltage and amperage ratings, including:

• Industrial automation and process control
• Programmable Logic Controller (PLC) interface
• Heating element and motor control
• Lighting systems

When to Replace

• Relay fails to activate the load circuit when control voltage is applied.
• Relay remains in the "on" state, continuously powering the load circuit regardless of control voltage.
• Intermittent or unreliable switching performance.
• Visible signs of damage or overheating on the relay housing or terminals.

Installation Tips

• Disconnect all power sources before installation or servicing.
• A heat sink is required for reliable operation with loads exceeding 10A to prevent thermal failure.
• Apply a thin layer of thermal compound between the relay's metal base and the heat sink surface.
• Ensure all wire connections to the screw terminals are secure to prevent poor contact and overheating.
• Verify that your application's control and load voltages are within the specified ranges for this relay.
