Product Information

Full details

This Finder PCB Mount Power Relay Module is designed for engineers and hobbyists working with industrial and consumer electronics who need a reliable switching component. Its key benefit is enabling control of higher voltage/current circuits using a low-voltage signal. A potential caveat is that it requires careful consideration of the 230V AC coil voltage and appropriate safety measures during installation. This module features a 230V AC coil, a 16A switching current, and a Single Pole Double Throw (SPDT) contact configuration, making it versatile for various applications.

FAQs

What is the coil voltage for this relay module?

The coil voltage for this Finder module is 230V AC, suitable for operation at 50Hz or 60Hz.

What is the maximum current this relay can switch?

This relay module is rated for a maximum switching current of 16A.

What does SPDT mean for this relay?

SPDT stands for Single Pole Double Throw. It means the relay has one set of contacts that can switch between two different circuits – one normally closed (NC) and one normally open (NO).

Is this relay suitable for DC loads?

This relay is designed for AC loads and AC control voltage. While it might switch DC loads, its performance and lifespan could be significantly affected due to different arcing characteristics. It's recommended to use relays specifically designed for DC switching.

What is the degree of protection (IP rating) for this relay?

The degree of protection is IP20, which means it is protected against solid objects larger than 12.5mm (like fingers) but offers no protection against water.

Can I use this relay for latching applications?

No, this is a mono-stable (non-latching) relay. It will only remain in its energized state as long as the 230V AC control signal is applied to the coil.

What are the physical dimensions of this relay?

The relay has compact dimensions with a width of 12.4mm, a height of 25mm, and a depth of 29mm.

Troubleshooting

Relay does not activate when control signal is applied.

Verify the control signal voltage is a stable 230V AC and is correctly connected to the coil terminals (A1, A2). Check for any breaks in the control wiring. Ensure the coil is not faulty.

Relay is stuck in the energized or de-energized state.

Check if the control signal is continuously applied or removed as expected. Ensure no external factors are physically impeding the relay's armature movement. If the relay is physically damaged, it may need replacement.

Contacts are welded or not making proper connection.

Ensure the switched current does not exceed the 16A rating. Arcing due to switching inductive loads can cause contact damage. For such loads, consider using a snubber circuit or a relay with higher contact ratings. Inspect contacts for damage or wear; replacement may be necessary.

Overheating during operation.

Confirm the switched load current is within the 16A limit. Ensure adequate ventilation around the relay on the PCB. If the relay is continuously switching high currents, it may be operating beyond its rated duty cycle or require heatsinking if applicable.

Pros and Cons

Pros

  • Reliable switching for power applications.
  • Versatile SPDT contact configuration.
  • Designed for standard 230V AC control signals.
  • Compact form factor for PCB mounting.
  • Suitable for industrial and consumer electronics.

Cons

  • Requires careful handling of 230V AC.
  • IP20 rating offers limited protection against environmental factors.
  • Mono-stable design may not be suitable for latching applications.
  • Specific coil voltage (230V AC) limits direct use with lower voltage control systems without modification.

Setup, Compatibility & Care

Setup:

  1. Power Off: Ensure the power supply to both the control circuit and the load circuit is completely disconnected before installation.
  2. Wiring: Connect the 230V AC control signal to the relay coil terminals (typically marked 'A1' and 'A2'). Connect the load through the single pole double throw (SPDT) contacts (typically marked '1', '2', '3' for Common, Normally Closed, Normally Open respectively).
  3. PCB Mounting: Solder the relay's pins securely to the designated pads on your Printed Circuit Board (PCB).
  4. Power On: Once wiring is verified, reconnect power.

Compatibility:

  • Coil Voltage: This relay is designed for a 230V AC control voltage at 50Hz or 60Hz. Ensure your control signal matches this requirement.
  • Switching Load: The relay can switch loads up to 16A. Ensure your load's current and voltage requirements are within these limits. For inductive loads, consider adding a snubber circuit.
  • Environment: Suitable for dry, indoor environments due to its IP20 rating.

Care:

  • Cleaning: Use a dry, soft brush to remove dust from the relay. Avoid using liquids or solvents, as this can damage the components and compromise its electrical insulation. Ensure the device is de-energized before cleaning.
  • Ventilation: Ensure adequate airflow around the relay when in use, especially if switching high currents, to prevent overheating.
