❓ Frequently Asked Questions

Q: What does the 4 CO (Changeover) contact configuration on the APD-500 mean?

A: CO (Change Over) contacts switch between two circuits — the common terminal connects to either NO or NC depending on the device state. Used for dual-purpose indication or reversing circuits.

Q: How do I test the APD-500 relay in the field without a signal source?

A: Most Leading Brand relays can be manually forced using the test button (if fitted) — this mechanically closes the relay contacts without energising the coil, allowing functional testing of the controlled circuit. For coil testing, use a multimeter to measure coil resistance (typically 500–2000Ω for AC coils at rated voltage) and compare with datasheet values.

Q: Can the APD-500 relay be mounted on a DIN rail socket for easy replacement?

A: This Leading Brand relay typically requires direct panel or DIN rail wiring. For applications requiring frequent relay replacement, consider the plug-in relay variant of this series with a matching socket base.
