ERDI436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

Econo-Timers are a combination of digital electronics and

an electromechanical relay. DPDT relay output for relay

logic circuits, and isolation of input to output voltages. For

applications, such as interval on, pulse shaping, minimum run

time, etc. The ERD Series is encapsulated to protect the

circuitry from shock, vibration and humidity.

Operation (Interval)

Upon application of input voltage, time delay begins, and output

relay energizes. At the end of time delay, output de-energizes

until input voltage is removed.

Reset: Removing input voltage resets the time delay and

the output.

Operation (Single Shot)

Input voltage must be applied before and during timing. Upon

momentary or maintained closure of initiate switch, output

relay energizes for time delay. At the end of the delay, output

de-energizes. Opening or reclosing initiate switch during timing

has no affect on time delay. Output will energize if initiate switch

is closed when input voltage is applied.

Reset: Reset occurs when time delay is complete & initiate

switch is opened. Loss of input voltage resets time delay

and output.
