Featuring a clear LED display and programmable timing modes, this relay allows users to set precise delay times for switching operations, enhancing automation efficiency and process control.
Multiple Timing Modes: Supports ON-delay, OFF-delay, interval timing, and cyclic timing, adaptable to diverse control requirements.
Wide Timing Range: Offers adjustable time settings from 0.1 seconds to 999 hours, covering both short and long duration applications.
High Precision: Digital quartz timing ensures an accuracy of ±0.1% of the set time, eliminating mechanical drift found in analog relays.
User-Friendly Interface: Intuitive push-button programming with real-time display of remaining time and selected mode.
Wide Voltage Compatibility: Operates with both AC (24V-240V) and DC (12V-240V) power supplies, reducing inventory needs.
The DH48S is ideal for:
Industrial Automation: Controls motor starting sequences, conveyor belt operation, and machine tool cycles.
Lighting Systems: Automates streetlight switching, emergency lighting delays, and commercial building occupancy-based lighting.
HVAC Systems: Schedules fan operation, compressor start/stop, and defrost cycles in refrigeration units.
Transportation Equipment: Used in elevators for door closing delays and in railway signals for timed phase changes.
Q: How many timing modes does the DH48S support?
A: It offers 8 different timing modes, including single-shot, repeat cycle, and dual-setting modes for complex sequences.
Q: Can it be triggered externally?
A: Yes, optional models include external trigger inputs for start/reset functions, enabling integration with sensors or control signals.
Q: What is the mechanical lifespan of the output contacts?
A: The relay provides up to 500,000 operations at rated load (10A/250V AC), ensuring long-term reliability.
Q: Is there a version with a built-in backup battery?
A: Yes, battery-backed models retain settings during power outages, ensuring uninterrupted timing operations.
