TD Series Time DelaysStandard Features / Specifications• Three styles available: Delay on Make, Delay on Break & By – Pass• Fixed or adjustable delay ranges• Initiate timer in 70 milliseconds• Broad input voltage range (Pilot Circuit)19 to 250 VAC/VDC, 50/60 Hz (TD60, TD70 TD32)19 to 130 VAC/VDC, 50/60 Hz (TD74)• Maximum load 1.0 amp, 10 amp inrush• Varying models work with or without anticipator type thermostats• Terminal or wire connections availableTime Delays• Operating Temperature Range 0°F to +160° F (-18°C to +71°C)• Compact Size 2” x 2” x .075” (5.08 x 5.08 x 1.9 cm)• Non positional single hole mounting• All parameters are subject to change as per special requirements• By – pass a control or device during start up• Helps to reduce power surges in multiple compressor applicationsGeneral Applications• Protection from short cycling of compressor• Ideal for compressor stagingTD60 SeriesDelay on Make Timers (DOM)Mode of Operation• Upon application of power the time delay initiates. Oncompletion of selected delay period, the load is energized.Timer will reset on power interruption or when thermostatdisconnects.Timing DiagramDELAY RANGE DELAY RANGEPART NO.
