H3FA-A, H3FA-B, H3FA-SA, H3FA-SB When the input voltage is applied, the CR oscillator circuit in the Timer starts to oscillate via the power supply circuit, the counter circuit counts up to the preset setting, and an output signal is produced. A transistor amplifies this signal to drive the load. 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.

Do not wire the terminals so that an external voltage is applied (∗1) to these input terminals or so that the negative side of the power supply is connected to these input terminals but not connected to power supply terminal 1 (∗2). No isolation is provided, so if voltage is applied to these terminals, unwanted current paths will be created and destroy the internal circuits.

(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 a 12 V DC power supply.) When connecting an external resistor to the Timer, connect it between terminals 21 and 23, and open terminals 21 and 22. Refer to External Resistors and Operating Time (Reference Value) on page 8. When operating with an external reset input, short terminals 1 and 4. The Timer will start operating even if reset terminals 1 and 4 are open when the power is turned ON. In this case, the current flow is approximately 0.1 mA. If a contact is used for control, use a contact with high contact reliability, If a transistor is used for control, use an ICEO of 10 μA and a VCE (sat) of 0.5 V or less. By opening the terminals connected to the internal variable resistor, Timer operation can be interrupted to enable the Timer to perform time integration operations. Interrupt Timer operation by opening terminals 21 and 22 when using the internal variable resistor or terminals 21 and 23 when using the external resistor. Timer operation can be resumed by reconnecting the terminals. ON Power supply (terminals 1 and 24) (See note.) OFF ON 10 ms min.

(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 DCoperated model with a 12 V DC power supply.) An output is produced immediately and is reset when the set time has elapsed. 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 DCoperated model with a 12 V DC power supply.) An output is produced immediately. If the start input is applied constantly, however, the reset input can be applied until the set time elapses to stop time-limit operation. (An output is produced when the start input is applied even when the constant reset input is ON prior to the start input.) If the reset input is applied (short terminals 4 and 1) with no start input (open terminals 6 and 1) while the Timer is operating, the Timer stops operating and the output is reset. When operating with an external start or reset input, the current flow from terminal 6 to terminal 1 (start input) or from terminal 4 to terminal 1 (reset input) is approximately 0.1 mA. A highly reliable contact is therefore recommended for the start and reset inputs. Use an ICEO of 10 μA and a VCE (sat) of 0.5 V or less for transistor control. When connecting an external resistor to the Timer, connect it between terminals 21 and 23, and open terminals 21 and 22. Power supply (terminals 1 and 24) (See note 1.)

Do not use leads that are longer than 30 cm. • The diagrams on the right show typical data. Setting differences exist for individual products. If accuracy is required, use a variable resistor and adjust the time. (If the leads are too long, the time will vary somewhat and variations in the operating time will increase.) H3FA-A/-SA/-AU/-SAU Operating time (%) Refer to the following characteristics diagrams when using an external resistor. 120 100 80 120 100 80 60 60 40 40 20 20 0 0.5 1 1.5 External resistor (MΩ) 0 1 2 3 4 External resistor (MΩ) ■ Extending the Reset Time DIP Timers have a shorter reset time than that of conventional timers for use in solid-state circuit applications. To extend the reset time to that of conventional timers, i.e., about 100 ms, during operation, connect the Timer to a capacitor from the table as shown in the following diagram. The reset time after the set time has elapsed will vary with the load relay, so select an appropriate capacitor for the load relay.

Otherwise, it may be damaged. • When more precise operating time settings are required, measure the operating time prior to use and adjust the time setting knob accordingly. • Be very careful when handling terminal leads. • Do not touch terminals with hands or objects that may be statically charged from mounting, transport, or other activities. Otherwise, the terminals may be damaged. Discharge static prior to handling the Timers by touching a grounded object or by using another method. • Refer to the following diagram for the set values for various operating times. Environmental Precautions • Store the H3FA within the specified ratings. If the H3FA has been stored at a temperature of –10°C or lower, let it stand for 3 hours or longer at room temperature before turning ON the power supply. • Use the H3FA within the specified ratings for operating temperature and humidity. • 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. Usage Precautions • Install a switch or circuit breaker that allows the operator to immediately turn OFF the power, and label it to clearly indicate its function. • Be sure to wire the terminals correctly. • Internal elements may be destroyed if a voltage outside the rated voltage is applied. • Maintain voltage fluctuations in the power supply within the specified range.

Do not clean without this sealing tape affixed. Use alcohol type (IPA, ethanol) solvent, which are less chemically reactive. Note that use of other solvents may damage the materials used for the Timer. Clean the Timer in less than 2 minutes. The cleaning solution must be 50°C or less. The tails of the connecting leads are solder-plated with consideration given to temperature at the time of soldering. When soldering the leads, keep the temperature at 260°C±5°C and complete soldering within 10 s. Do not use ultrasonic cleaning.. sealing tape * ALL DIMENSIONS SHOWN ARE IN MILLIMETERS.
