TSD2 SERIES

IntervalTimer

Description

The TSD2 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 (Interval)

Upon application of input voltage, the time delay begins. The

output is energized during the time delay. At the end of the time

delay, the output de-energizes and remains de-energized until

input voltage is removed.

Reset: Removing input voltage resets the time delay and output.
