OMRON DH48S-2Z Digital Timer Relay

Model: DH48S-2Z

Voltage Rating: Operates on an input supply of 200/220/240V AC (50/60Hz), making it highly compatible with standard industrial power grids.

Ultra-Wide Timing Range: The timing setting ranges from a minimum of 0.01 seconds up to 99 hours and 99 minutes.

Time Base Flexibility: The center switch modifies the unit scale (e.g., S for seconds, M for minutes, H for hours), ensuring versatile programming options.

Output Contact Type: Configured as a DPDT (Double Pole Double Throw) relay output, giving it two sets of independent open/close contacts (2 NO + 2 NC). Unlike the standard DH48S-1Z variant, the 2Z variant outputs two delayed contacts and does not utilize external physical reset/pause terminal inputs.

High Precision: Engineered with digital integrated circuits that achieve a delay control accuracy of ≤ 0.3% ± 0.05 seconds, vastly outperforming analog potentiometer knobs.

Contact Capacity: Typically rated for 5A at 220V AC / 30V DC (resistive loads). For heavy inductive loads (like large motors or pumps), it should be paired with an AC contactor.
