FAQs

What is the switching capacity of this relay?

The relay contacts are rated for 8 Amps at 250 Volts AC.

What coil voltage does this module require?

This module requires a 24VAC coil voltage for operation.

What is the purpose of the integrated varistor?

The varistor provides surge suppression, protecting the relay coil from transient voltage spikes, which can extend its operational life.

Can this relay be used for DC loads?

While primarily designed for AC loads, it might be possible to switch low-power DC loads, but it's recommended to consult the manufacturer's datasheet or test thoroughly, as DC switching characteristics differ significantly from AC.

How do I identify the NO and NC contacts?

Typically, terminals are marked. The 'common' terminal connects to either the 'normally closed' (NC) terminal when de-energized, or the 'normally open' (NO) terminal when energized.

What are the physical dimensions of the module?

The module has dimensions of 15.8mm in length, 75.3mm in depth, and 78.6mm in height.

What material are the contacts made of?

The contact material is AgNi (Silver-Nickel), known for good conductivity and durability.

Troubleshooting

Relay does not energize when control signal is applied.

Verify the 24VAC power supply is connected correctly to the coil terminals (A1/A2) and that the voltage is within specification. Check wiring integrity and ensure the control signal is active.

Relay chatters or does not reliably switch.

Ensure the 24VAC coil voltage is stable and within tolerance. Check for loose wiring connections. Inspect contacts for any signs of damage or contamination.

Load does not switch ON or OFF when relay is energized.

Confirm that the load is wired correctly through the normally open (NO) or normally closed (NC) contacts as intended. Check the load circuit itself for faults and ensure the load does not exceed the relay's 8A/250VAC rating.

LED indicator is not lit.

Check that the coil voltage is applied and correct. If the voltage is correct and the LED is still off, the LED itself may be faulty, or there could be an internal issue with the relay module.

Pros and Cons

Pros

  • Reliable switching for AC loads.
  • Compact and space-saving design.
  • Integrated protection enhances durability.
  • Clear LED status indication.
  • Secure screw terminal connections.

Cons

  • Requires a 24VAC power supply, limiting direct use with other voltages without conversion.
  • Limited to AC switching; not suitable for DC loads without appropriate considerations.
  • May require additional external components for specific safety or control requirements.
  • Higher input current (46mA) compared to some ultra-low power relays.

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely mount the module onto a standard DIN rail (35mm) within your control enclosure. Ensure adequate ventilation around the unit.
  2. Wiring: Connect the control circuit to the coil terminals (typically A1/A2) using the 24VAC power source. Wire the load circuits through the changeover contacts (common, normally open, normally closed terminals).
  3. Connection Type: Utilize the screw terminals for all electrical connections, ensuring wires are properly stripped and secured for a firm grip. Torque screws according to manufacturer recommendations if available.

Compatibility:

  • Coil Voltage: This module is specifically designed for a 24VAC coil voltage. Ensure your control system's output matches this requirement. Using incorrect voltages can damage the relay.
  • Load Type: Primarily designed for AC loads up to 8A/250VAC. Verify that your connected load does not exceed these ratings.

Care:

  • Cleaning: Disconnect power before cleaning. Use a dry or slightly damp cloth to wipe the exterior. Avoid using solvents or abrasive cleaners.
  • Environment: Operate within the specified temperature and humidity ranges to ensure optimal performance and longevity. Keep the module free from excessive dust and moisture.
