Solid-state Timer with Variable Time Ranges

Time Ranges

Four time ranges are available for each timer by changing the time range selector switch positions to different combinations.

Time range code Time range selector switch
A 0.05 to 0.5 s 0.5 to 5 s 0.05 to 0.5 min 0.5 to 5 min
B 0.1 to 1 s 1 to 10 s 0.1 to 1 min 1 to 10 min
C 0.3 to 3 s 3 to 30 s 0.3 to 3 min 3 to 30 min

Time range code Time multiplying key
D 0.1 to 1 min 1 to 10 min 0.1 to 1 hrs 1 to 10 hrs
E 0.3 to 3 min 3 to 30 min 0.3 to 3 hrs 3 to 30 hrs

Ratings

Rated supply voltage 100/110/120 VAC (50/60 Hz), 200/220/240 VAC (50/60 Hz),
12, 24, 48, 100, 110 VDC *2
Operating voltage range AC: 85% to 110% of rated supply voltage
DC: 80% to 110% of rated supply voltage *3
Power consumption AC: Approx. 5 VA/2 W
DC: Approx. 2 W
Control outputs 5 A at 250 VAC, resistive load (cosφ = 1)

*1. Color indicators for the rated voltage are provided on the front of the Timer.
       Blue: 100/110/120 VAC
       Red: 200/220/240 VAC
       None: Other voltages
*2. With DC ratings, single-phase full-wave rectified power sources may be used.
*3. 90% to 110% for 12-VDC models.
