Note: 1. DC ripple rate: 20% max. if the power supply incorporates a single-phase, full-wave rectifier.
2. Do not use an inverter output as the power supply. Refer to Power Supplies in Safety Precautions for All Timers on page 51 for details.
3. Models with 24-to-48-VAC or 12-to-48-VDC power supply have inrush current. Caution is thus required when turning ON and OFF power
to the Timer with a non-contact output from a device such as a sensor. (Models with an inrush current of approximately 50 mA and a 24VDC power supply are available (the H3CR-A-302 and H3CR-A8-302).)

power supply circuit. Thus, an NPN
transistor can be connected.
Note: Refer to the signal levels in the fol-
lowing table and be aware of the
minimum applicable load of the relay.

Operation
■ Timing Chart
Note: 1. The minimum power-opening time (“Rt”) is 0.1 s.
2. The minimum input pulse width (for start, reset) is 0.05 s.
3. The letter “t” in the timing charts stands for the set time and “t–a” means that the period is less than the time set.
4. Power supply start in mode J is also possible for H3CR-A8/-A8E/-A8S/-A8-301 models.
5. Refer to page 19 for application examples.
