TIMING MODE:
Delay on operate begins upon application of input power. The
load is energized at the end of the delay period and remains so
until input power is removed.
TIMING DIAGRAM:
CONTACT INFORMATION:
Solid state switching device 1 form A; normally open series connection
.
Continuous current rating 3 amperes. Maximum inrush 20 amperes.
Voltage drop 2.5 volts RMS or less @ 3 amperes.
(For 10 ampere load current rating consult factory).
NOTE: Maximum current rating for 110V DC is 2 amperes (heat sink required).
TIMING SPECIFICATIONS:
Two timing ranges available:
.2 to 102.3 seconds in increments of 0.1 second and
1 to 1023 seconds in increments of 1 second.
Custom timing available.
Timing adjustment by means of a 10 position DIP switch
encoded in binary format (1, 2, 4, 8, etc.)
Timing accuracy: +/-5% plus 1/2increment
Timing repeatability: 2%
Timing cycle interrupt transfer: none
