Frequently Asked Questions
Q: What voltage options does the DH48S-S timer relay switch support?
A: The DH48S-S programmable timer relay supports a wide range of AC and DC voltages including 12V, 24V, 36V, 110V, 220V, and 380V, making it suitable for a broad variety of residential, commercial, and industrial electrical applications.
Q: What is the timing range of this digital repeat cycle timer relay?
A: The timing range spans from 0.1 seconds up to 99 hours, giving you exceptional flexibility whether you need very short interval cycling or extended long-duration timing schedules.
Q: Can this timer relay handle high-current loads directly?
A: The DH48S-S has a contact capacity of 5A DC30V / 5A AC220V for resistive loads. For driving larger current loads beyond this rating, it is recommended to use the relay in combination with an appropriately rated AC contactor.
Q: How does the reset function work on the DH48S-S?
A: To reset the timer at any point during operation, connect a wire to terminals 1 and 3. This immediately returns the relay contacts to their original (default) position. When the reset wire is disconnected, the timer restarts its count from zero. Use shielded wire for the reset and pause terminals to minimize electrical interference.
