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.
