Littelfuse, Inc. Multifunction Time Delay Relay TRDU120A2

Description
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.

The TRDU120A2 is a multifunction time delay relay with an 8-pin SPDT relay output, designed for 120VAC operation. It features 21 selectable timing functions, switch-selectable timing ranges from 0.1s to 1,705h, and ±0.1% repeat accuracy. The relay provides 10A resistive load capacity at 120/240VAC and 28VDC, with mechanical life of 1×10⁷ operations and electrical life of 1×10⁶ operations. It includes LED indicators for input voltage and output status, and mounts on a 35mm DIN rail or via surface mounting with two #6 screws. Dimensions are 76.7 mm H × 60.7 mm W × 45.2 mm D, with an operating temperature range of -20°C to 65°C and storage temperature range of -40°C to 85°C. Isolation voltage is ≥1500V RMS, and insulation resistance is ≥100 MΩ. Power consumption is ≤3W. The unit is microcontroller-based and reverse polarity protected for DC operation, though this model is AC-powered.
