Specifications
■General
*The internal circuits are optically isolated from the output. This enables universal application as NPN or PNP transistor.
For details, refer to your OMRON website.
■Time Ranges
Note: When the time setting knob is turned below “0” until the point where the time setting knob stops, the output will operate instantaneously at
all time range settings.
For details, refer to your OMRON website.

■Ratings
Note: 1. DC ripple rate: 20% max. (A single-phase, full-wave-rectification power supply can be used).
2. Do not use an inverter output as the power supply. Refer to your OMRON website 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 24-
VDC power supply are available (the H3CR-A-302 and H3CR-A8-302).)
For details, consult your OMRON sales representative.
4. The values are for when the terminals 2 and 7 and terminals 10 and 6 are short-circuited, and include the consumption current of the
input circuit.
5. Refer to your OMRON website when using the Timer together with a 2-wire AC proximity sensor.

11-pin Models
Note: Terminals 1, 3, 4, and 8 are empty. Terminals 2, 5, 6, 7, and 10
are the same as for the H3CR-A.
Note: 1. Terminal 5 is empty.
2. Separate power supplies can be used for the Timer and in-
puts.

Operation
■Timing Chart (Refer to page 20 for application examples.)
H3CR-A/-AS/-AP*/-A-301
Note: 1. Allow at least 0.1 s for the Timer reset time if the power supply is reset due to an interruption in the power supply.
2. The minimum input pulse width (for start, reset) is 0.05 s.
3. The letter "t" in the timing charts indicates the set time, and "t-a" means that the period is less than the set time. (t - a < 1)
4. H3CR-AP model incorporates start input only. As such, the power supply is reset.
5. Model H3CR-AS only has operation equivalent to time-limit contact: NO.
6. When the setting dial is turned all the way past 0 for instantaneous output, "t" (set time) in the above time chart is 0-sec operation.
7. During timer operation, the flash frequency changes when 90% of the set time has been reached.

Note: 1. Allow at least 0.1 s for the Timer reset time if the power
supply is reset due to an interruption in the power supply.

3. The letter "t" in the timing charts indicates the set time, and
"t-a" means that the period is less than the set time.

4.
In J Mode, there will be only one output even if the start input is
longer than the set time.
5. H3CR-AP model incorporates start input only. As such, the
power supply is reset.
6. Model H3CR-AS only has operation equivalent to time-limit
contact: NO.
7. When the setting dial is turned all the way past 0 for
intantaneous output, "t" (set time) in the above time chart is
0-sec operation.
8. During timer operation, the flash frequency changes when
90% of the set time has been reached.
Note: The set time is the sum of t1 and t2.
Start and reset are also both enabled when the gate signal is ON.

3. Model H3CR-A8S only has operation equivalent to time-limit contact: NO.
4. When the setting dial is turned all the way past 0 for intantaneous output, "t" (set time) in the above time chart is 0-sec operation.
5. You can use J Mode to use the power supply as the start input.
6. During timer operation, the flash frequency changes when 90% of the set time has been reached.
