KSDB Series Information

  • Fixed or Adjustable 0.1s‑1000m in 6 Ranges
  • ±0.5% Repeat Accuracy
  • ±5% Factory Calibration
  • 12VDC to 230VAC in 6 Ranges
  • 1A, Solid‑State Output
The KSDB is designed for general purpose commercial and industrial applications where a small, cost effective, reliable solid‑state timer is required. The factory calibration for fixed time delays is within 5% of the target time delay. The repeat accuracy, under stable conditions, is 0.5% of the selected time delay. This series is designed for popular AC and DC voltages. Time delays of 0.1 seconds to 1000 minutes are available in 6 ranges. 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‑Break): Input voltage must be applied before and during timing. Upon closure of the initiate switch, the output energizes. The time delay begins when the initiate switch is opened. The output remains energized during timing. At the end of the time delay, the output de‑energizes. The output energizes if the initiate switch is closed when input voltage is applied. Reset: Reclosing the initiate switch during timing resets the time delay. Loss of input voltage resets the time delay and output.
