Ratings
Rated supply voltage 100/110/120 or 200/220/240 VAC (50/60 Hz);
24, 48, 100, or 110 VDC (permissible ripple: 20% max.)
Operating voltage range 85% to 110% of rated supply voltage
Power consumption AC: approx. 0.5 VA; DC: approx. 0.7 W
Control outputs 5 A at 250 VAC, resistive load (cos
%
=1)
Minimum permissible load (ref. value): 10 mA at 5 VDC, 100 mA at 5 VDC (-8R)
Note: When power is applied to any of the H3B series Timers, an initial current of approx. 0.3 A flows for approx. 1 s (M series), 0.1 s (S
series), irrespective of the rated supply voltage of the Timer.

Note: 1. When the Timer is set at a rated time of 0.5 s or 1 s, add
!
10 ms to the respective characteristics.
2. Resetting time means the minimum power application time for power OFF-delay Timer.
If less, the output relay may not release.
