TRDU Series - Multifunction Time Delay Relay

Littelfuse Multifunction Relays
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.
