... H3FA-SB H3FA-SBU Note: 1. The above timing ranges apply when the internal variable resistor of H3FA is used. 2. The external variable resistor may also be used by opening the terminal connected to the internal variable resistor. 3. Wire the appropriate terminal to select a time setting range. Refer to Rated Time and Terminal Connections on page 4 for details. ...

... Note: 1. Short-circuit terminals 21 and 22 when using the internal variable resistor of H3FA external resistor can also be used by opening terminals 21 and 22. When using an external resistor (1 MΩ for H3FA-A/-SA, 3 MΩ for H3FA-B/ -SB), connect it between terminals 21 and 23. The voltage across the H3FA-SA and -SB (solid-state output loads) is the load input voltage minus the residual voltage when the transistor turns ON ...

... Timing Charts and External Connections Note: Do not apply voltage to any terminals other than the power supply terminals. Otherwise, the internal circuits may be damaged. H3FA-A, H3FA-B, H3FA-SA, H3FA-SB Standard Operation (ON-delay operation) When the power is turned ON and the set time has elapsed, an output is produced ...

... H3FA-AU, H3FA-BU, H3FA-SAU, H3FA-SBU One-shot Output Operation Turn ON the power and apply a start input (short terminals 6 and 1). (Power turns ON when power terminals 1 and 24 are shorted or when terminals 13 and 15 are shorted when using a 12/24 V DC- operated model with power supply.) An output is produced immediately and is reset when the set time has elapsed ...

... Refer to the following characteristics diagrams when using an external resistor. • Use an external resistor rated at about 0.1 W/1 MΩ for H3FA-A, -SA, -AU, and -SAU or 0.1 W/3 MΩ for H3FA-B, -SB, -BU, and - SBU. • Do not run leads parallel to power lines and keep the leads shorter than minimize the effects of external noise. • ...

... Do not operate the H3FA in locations subject to sudden or extreme changes in temperature, or locations where high humidity may result in condensation. • Do not use the H3FA in locations subject to vibrations or shock. Extended use in such locations may result in damage due to stress. • Do not use the H3FA in locations subject to excessive dust, corrosive gas, or direct sunlight ...
