How to Set the Timer
- Wire the relay according to the included wiring diagram.
- Use the "Time Step" knob to select your desired time range (e.g., 10 s, 100 m, 100 h).
- Use the "t" knob to dial in the precise delay value within that range.
- Pro Tip: For highly accurate settings at longer intervals, first set the time step to a lower range, verify the timing with a reference device, then scale up to your target range for greater precision.
- Power on your circuit. The relay begins counting immediately. The LED indicator activates simultaneously with contact switching. When the set time elapses, the relay latches and remains stable until power is removed.
Maintenance
Disconnect the relay from power before any cleaning. Wipe the housing with a dry swab — avoid conductive materials or chemical solvents that could damage internal components. Verify normal operation after cleaning.

Frequently Asked Questions
Q: What voltage does this time delay relay operate on?
A: This relay is rated for AC 220V coil voltage and switches contacts at up to AC 220V / 5A. It is designed for standard AC220V electrical systems used in industrial and residential panels.
Q: What is the adjustable delay range of this timer relay?
A: The delay range is fully adjustable from as short as 0.1 seconds up to 100 hours, giving you exceptional flexibility for both rapid cycling and long-duration timing tasks.
Q: How do I install this relay in my control panel?
A: This relay uses a standard DIN rail mount, making installation straightforward — simply snap it onto your existing DIN rail inside the panel and wire it according to the provided diagram. No special tools are required for mounting.
Q: What does 1NO + 1NC contact configuration mean?
A: 1NO (Normally Open) means the contact circuit is open at rest and closes when the relay activates. 1NC (Normally Closed) means the circuit is closed at rest and opens upon activation. Having both gives you maximum wiring flexibility for your specific control logic.
Q: Can this relay be used in both industrial and home applications?
A: Yes. This multifunction timer relay is suitable for a wide range of applications including industrial automation, factory equipment, HVAC controls, lighting timers, and general-purpose residential electrical control panels — anywhere a precise, adjustable time-delay switch is needed on an AC220V circuit.
