Plug-In Analog Solid-State Delay On Make Timers - TDU Timers

Plug-In Analog Solid-State Delay On Make Timers
TDU Timers

The TDU Delay on Make units are high performance analog solid-state timers with octal, magnal round and QC bases for plug-in installation. They incorporate relays which can handle up to 10 amp loads in SPDT, DPST and DPDT formats. The metal enclosure provides a high degree of RFI shielding.

Timing Mode

Application of input voltage to the timer starts the time delay. At the end of the delay period, the load is energized. To reset, remove the input voltage to the timer.

FEATURES
  • High-performance RC solid-state timing
  • Industrial 10 amp relay, isolated load handling
  • Standard AC voltage range choices
