Programmable Encapsulated Time Delay Relays

The THR-3 Series products are designed to replace thousands of products from Macromatic and many other manufacturers with just three Catalog Numbers. Each comes with four functions & four timing ranges covering 0.1 second to 100 minutes (1,000 minutes on THR-3856U dual time unit). On the same unit, choose between onboard adjustable, onboard fixed & remote adjustable time delay setting (remote time delay not available on THR-3856U). All set up is done with DIP switches for ease of use. A universal input voltage of 24-240V AC & 12- 125V DC adds to the ultimate flexibility of these products. All products are encapsulated for protection against harsh elements. A 10A SPDT relay output rating can handle most pilot duty & fractional HP loads.

 

The new THR-3 Series has only three catalog numbers, but each one offers these features:

 

  • Multi-Function--four of the most common time delay functions are built-in
  • Universal Voltage--an input voltage of 24-240VAC & 12-125VDC covers almost any application
  • Programmable Time Delay--four time ranges covering 0.1S to 100M (1,000M on THR-3856U)--choose between onboard or remote adjust--you can even replace a timer with a fixed delay
  • Easy to Program--Six DIP Switches can program all of the above
