Solid-state Timer

H3BA-N

■ Ratings

Note: 1.

DC ripple rate: 20% max.

2.

Models other than 24-VDC H3BA-N models cause an inrush current. Pay careful attention when attempting to turn on power to such

models with non-contact output from a device such as a sensor.

3.

90% or higher if the Timer is used continuously at a high ambient temperature.

■ Characteristics

Note:

For setting the time-limit of the Timer to a cycle of less than 3 seconds or applying the forced reset, use the H3BA-N in mode D (signal OFF-

delay).
