Dip Timer H3FA
Caution
Product Description
Timer for mounting on contact and non-contact output type printed circuit boards.
[Features]
· Timer for mounting on contact and non-contact output type printed circuit boards.
· Two types of control outputs are provided: 3 A (at 250 V AC, with resistive load) for contact outputs (1a, 1b), and max. 150 mA at high capacity for non-contact outputs.
· Multifunctionality realized by 4 time types in one unit: 1 sec. / 10 sec. / 1 min. / 10 min. (type A) or 6 sec. / 60 sec. / 6 min. / 60 min. (type B).
· Time can be operated remotely through connection to an external varistor.
· Fully washable.
· Compact size enables mounting in 1-inch pitch racks (length × width × height: 17.75 × 36.9 × 19.5 mm).
· Complies with UL/CSA.

Time Specifications
| Format | Maximum Scale Time | Set Time Range |
|---|---|---|
| Series H3FA-A Series H3FA-SA Series H3FA-AU | 1 s | 0.1 to 1 s |
| 10 s | 1 to 10 s | |
| 1 min | 0.1 to 1 min | |
| Series H3FA-B Series H3FA-SB Series H3FA-BU | 6 s | 0.6 to 6 s |

Note 1. The above timing ranges apply when the internal variable resistor of Series H3FA is used.
Note 2. The external variable resistor may also be used by opening the terminal connected to the internal variable resistor.
Note 3. Wire the appropriate terminal to select a time setting range.
