THDS431C工業(yè)自動化與控制的延時繼電器規(guī)格書PDF中文資料

Description

The THDS 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 (Single Shot)

Input voltage must be applied before and during timing. Upon

momentary or maintained closure of the initiate switch, the

output energizes for a measured interval of time. At the end

of the delay, the output de-energizes. Opening or reclosing the

initiate switch during timing has no affect on the time delay.

The output energizes if the initiate switch is closed when input

voltage is applied.

Reset: Reset occurs when the time delay is complete and the

initiate switch is opened. Loss of input voltage resets the time

delay and output.
