Time Delay Relays Multifunction TRDU SERIES 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 8-PIN switches located on the face of the unit. Two LEDs 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. 11-PIN Features & Benefits L1 N/L2 Wiring Diagram FEATURES BENEFITS L1 N/L2 Multifunction: Replace hundreds of parts and reduce stocking 21 timing functions requirements Microcontroller based Repeat Accuracy + / - 0.1% User selectable Timing settings are switch selectable 0.1s - 1,705h time delay in eight ranges for added flexibility Isolated 10A, SPDT or Allows control of loads for AC or DC voltages L1 N/L2 L1 N/L2 DPDT output contacts Provides visual indication of input voltage and 8-PIN DPDT 8-PIN SPDT LED indicators relay status L1 N/L2 Accessories V = Voltage BZ1 Front Panel Mount Kit S1 = Initiate Switch Provides an easy method of through-the-panel L1 N/L2 L1 N/L2 mounting of 8- or 11-pin plug-in timers, flashers, and other controls.
