TRDU Series
Time Delay Relay
DescriptionDescription
Description
DescriptionDescription
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 10 A isolated relay output contacts in either SPDT or DPDT. The TRDU replaces
hundreds of part numbers, thereby, reducing your stock inventory requirements.
