New Original Omron H3DT-F H3DT Series DIN Rail Timer Relay
1. Product Overview
The H3DT-F is an authentic brand-new DIN rail mounted timer relay belonging to Omron’s H3DT universal time delay relay lineup, developed for industrial automation timing logic control. This compact timing component adopts standard 35 mm DIN rail installation structure, designed for control cabinets, PLC peripheral matching, motor startup delay, lighting timing, equipment sequential operation and automated assembly line timing workflows.
H3DT-F integrates multi-mode timing functions, wide-range input voltage compatibility and stable mechanical contact output. It supports flexible delay time setting via front panel knobs and DIP switches, with strong anti-interference performance to adapt to harsh industrial environments including workshop electromagnetic interference, temperature fluctuation and vibration. As a core timing control unit, it separates power input and signal output circuits to achieve electrical isolation, and all original units comply with international safety and electrical performance standards for industrial low-voltage control.
2. Main Functions
- Multi-mode time delay control: Cover power-on delay, power-off delay, signal trigger delay and interval timing modes to satisfy diverse automation logic requirements.
- Standard DIN rail snap-on mounting: Quick installation and disassembly without extra fixed brackets inside electrical control cabinets.
- Adjustable wide timing range: Continuous time parameter tuning from milliseconds to hours via front rotary knob and DIP switch combination.
- Dual isolation output contacts: Independent relay contact terminals to drive small AC/DC loads such as contactor coils, indicator lamps and auxiliary valves.
- Universal wide voltage power supply: Compatible with multiple AC and DC supply voltages to reduce spare part inventory for equipment manufacturers.
- Visible working status indication: Built-in LED status light to display power supply, timing running and contact actuation states in real time.
- Anti-interference circuit design: Internal surge absorption circuit suppresses coil reverse electromotive force from peripheral contactors.
- Manual parameter reset function: One-click reset of timing cycle to restart timing procedures during equipment debugging.
- Wide ambient temperature adaptability: Maintain stable timing accuracy under low-temperature cold storage and high-temperature enclosed control cabinets.
- Modular compact structure: Small body size saves internal cabinet layout space compared to large independent timing controllers.
