Timing Mode

Apply input power for a minimum of 100 milli-seconds to assure time out. Instantaneous contact and timed contacts transfer. Remove input power, instantaneous contact drops out, timed contacts remain closed for duration of selected time (off-delay) then drop out. Reapply power for new cycle.

FEATURES
  • CMOS IC digital timing
  • Timing contacts and instantaneous contacts in same timer
  • Relays are sealed
  • Proven circuitry
  • Magnal (11 pin) plug-ins
  • Fixed or variable time adjustment
  • Timing ranges from .1 to 300 seconds standard (special time settings and ranges also available)
  • 0.1% Repeat accuracy
  • 100% Operational testing before shipping

BASIC WIRING AND DIMENSIONS
SPECIFICATIONS
