The TRDU24A3 is a multifunction time delay relay with an 11-pin DPDT relay output, rated for 10A resistive loads at 120/240VAC and 28VDC, or 1/3 hp at 120/240VAC. It accepts 24VAC or 24VDC input with a tolerance of -15% to +20%, and operates with a power consumption of ≤3W. Timing ranges are switch-selectable from 0.1s to 1,705h for single functions or 0.1s to 3,100m for dual functions, with ±1% accuracy or 50ms, whichever is greater. The device features two LED indicators for input voltage and output status, and is designed for 35mm DIN rail or surface mounting using the NDS-11 socket. It meets an isolation voltage of ≥1500V RMS and has a mechanical life of 1×10⁷ operations. Operating temperature ranges from -20°C to 65°C, with storage from -40°C to 85°C. Weight is approximately 164g.
The TRDU Series is a versatile universal time delay relay with 21 selectable single and dual functions. The dual functions replace up to three timers required to accomplish the same function. Both the function and the timing range are selectable with switches located on the face of the unit. Two LED’s indicate input voltage and output status. This device offers full 10A isolated relay output contacts in either SPDT or DPDT. The TRDU replaces hundreds of part numbers, thereby, reducing your stock inventory requirements.21 Functions: Five switches are provided to set one of 10 single or 11 dual modes of operation. See datasheet for a complete list of singe and dual functions.
