描述 Description

The THDB Series combines accurate timing circuitry with high

power, solid-state switching. It can switch motors, lamps, and

heaters directly without a contactor. You can reduce labor,

component cost, and increase reliability with these small,

easy-to-use, timers.

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.
