TSD4 Series Information

  • Fixed or Adjustable Delays from 0.1s‑100h
  • 24, 120, or 230VAC
  • ±0.1% Repeat Accuracy
  • ±1% Factory Calibration
  • 1A, Solid‑State Output
The TSD4 Digi‑Timer is a delay‑on‑make timer with a normally closed solid‑state output. The load is energized prior to and during the delay period. The TSD Series is designed for more demanding commercial and industrial applications where small size and accurate performance are required. The factory calibration for fixed time delays is within 1% of the target time delay. The repeat accuracy, under stable conditions, is 0.1% of the time delay. The TSD Series is rated to operate over an extended temperature range. Time delays of 0.1 seconds to 100 hours are available. The output is rated 1A steady and 10A inrush. The modules are totally solid state and encapsulated to protect the electronic circuitry.

Operation (Delay‑on‑Make NC): Upon application of input voltage, the load energizes immediately. When the initiate switch is closed, the time delay begins. At the end of the time delay, the load de‑energizes. Reset: When the initiate switch is reopened, the load energizes again and the time delay is reset. Removing input voltage resets the time delay.
