TIMING LIGHT LOGIC
The DMM Series offers selectable multiple
time ranges, functional logic modes and
universal input voltage range, all in one DIN
rail mount space saving Flatpak enclosure.
Programming is accomplished by using
two multi-position rotary switches. One
switch selects one of six time ranges. The
other switch selects one of five operating
logic modes. A 3-digit push-button switch
selects the amount of time required for a
timing cycle.
SPECIFICATIONS
TIME DELAY
Adjustment: 3 digit push-button switch
Range: 50 ms to 999 hours in 6 ranges
Repeatability: ±0.1% of set time or ±20 ms
whichever is greater
Accuracies: All functions ±1% of set time or ±20
Repeat Cycle: Full on during OFF time; Flashing
during ON time
Other Logic Modes: Flashing during timing; Full
on after time out
TIMING
Selectable Time Ranges: 0.05 to 9.99 sec.; 0.1
to 99.9 sec.; 1 to 999 sec.; 0.1 to 99.9 minutes;
1 to 999 minutes; 1 to 999 hours (times less than
50 ms are not recommended due to the response
time of the mechanical relay)
Selectable Operating Logic Modes:
Repeat Cycle (50% fixed duty cycle)
Single Shot (1 shot)
Delay On Break (D.O.B.)
Interval (Intervl)
Delay On Make (D.O.M.)
PROGRAMMING
To program the timer, remove voltage from the
unit and select the operating logic mode and the
time range; use the digital switches to select the
required time (0 to 999)
ms whichever is greater
INPUT
Operating Voltage: 24 to 240 VAC ±12%, 50/60
Hz; 24 to 240 VDC ±12%, (DC unfiltered input
voltage must be full-wave rectified)

Power Off Reset Time: Requires power interrup
tion of 150 ms max. (50 ms typical)
Start Switch Closure Time: 50 ms. min. to initi
ate timing cycle; 50 ms. min. to reset delay during
timing cycle
