■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.
Standard (0.05-s to 300-h) Models
Double (0.1-s to 600-h) Models
■Ratings
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 Safety Precautions for All Timers 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).)
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 Safety Precautions for All Timers when using the Timer together with a 2-wire AC proximity sensor.

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.

Application Examples (H3CR-A)
A Mode: ON-delay
ON-delay operation (A mode) is a basic mode.
1. Power-ON Start/Power-OFF Reset
The Power-ON start/Power-OFF reset operation is a standard
operating method.
2. Signal Start/Signal Reset
The Signal start/Signal reset operation is useful for remote control of
the Timer.
3. Control of Integrated Time with Gate
Signal
With a gate signal, the Power-ON start operation and Signal start
operation can be controlled (the operation can be interrupted).
B/B2 Mode: Flicker
The flicker operation in the B and B2 modes can be effectively
applied to lamp or buzzer (ON and OFF) alarms or the monitoring of
an intermittent operation with a display.

2. Signal Start/Signal Reset (in B Mode)
If there is an abnormal signal, flashing starts. When the abnormal
condition is restored, a reset signal stops the display flashing.
C Mode: Signal ON/OFF-delay
The Signal ON-/OFF-delay operation (C mode) is useful for the
control of distribution of products on a production line into boxes by
the specified number or time.
1. Power-ON Start/Instantaneous Operation/
Time-limit Reset
A set of these functions is useful for the operation of a machine for a
specified period when power is ON.
2. Signal-ON-OFF Start/Instantaneous
Operation/Time-limit Reset
D Mode: Signal OFF-delay
Signal OFF-delay operation (D mode) can be effectively used to keep
a load operating for a certain period. For example, this function
enables the cooling fan for a lamp or heater to operate for a certain
period after the lamp or heater is switched OFF.

Safety Precautions (H3CR-A)
Refer to Safety Precautions for All Timers.
Note: The following precautions apply to all H3CR-A models.
■Power Supplies
For the power supply of an input device of the H3CR-A@/-A@S/-AP,
use an isolating transformer with the primary and secondary
windings mutually isolated and the secondary winding not grounded.
The H3CR-A@/-A@S/AP’s power supply terminal 2 is a common ter-
minal for input signals to the Timer. Do not disconnect the wires on
terminal 2, otherwise the internal circuitry of the Timer will be dam-
aged.
Make sure that the voltage is applied within the specified range, oth-
erwise the internal elements of the Timer may be damaged.
■Input/Output
Relationship between Input and Power
Supply Circuits (except for H3CR-A8E)
The H3CR-A (except for H3CR-A8E) uses transformerless power
supply. When connecting a relay or transistor as an external signal
input device, pay attention to the following points to prevent short-
circuiting due to a sneak current to the transformerless power supply.
If a relay or transistor is connected to two or more Timers, the input
terminals of those Timers must be wired properly so that they will not
differ in phase, otherwise the terminals will be short-circuited to one
another.
It is impossible to provide two independent power switches as shown
below regardless of whether or not the Timers are different in phase.

Relationship between Input and Power
Supply Circuits (H3CR-A@/-A@S)
An appropriate input is applied to the input signal terminals of the
H3CR-A@/-A@S when one of the input terminals is short-circuited
with the common terminal (terminal 2) for the input signals. Never
use terminal 10 as the common terminal for this purpose, otherwise
the internal circuit of the Timer will be damaged.
Do not connect a relay or any other load between input terminals,
otherwise the internal circuit of the Timer will be damaged due to the
high-tension voltage applied to the input terminals.
Relationship between Input and Power
Supply Circuits (H3CR-AP)
Since the input circuit and the power supply circuit are configured
independently, the input circuit can be turned ON or OFF irrespective
of the ON/OFF state of the power supply.
It must be noted that a voltage equivalent to the power supply voltage
is applied to the input circuit.
If a relay or transistor is connected to two or more Timers, the input
terminals of those Timers must be wired properly so that they will not
be different in phase or the terminals will be short-circuited to one
another (refer to the figures below).
Common to All H3CR-A Models
With the H3CR-AP, input wires must be as short as possible. If the
floating capacity of wires exceeds 1,200 pF (approx. 10 m for cables
with 120 pF/m), the operation will be affected. Pay particular
attention when using shielded cables.
The H3CR-A@S transistor output is isolated from the internal
circuitry by a photocoupler. Therefore, either NPN or PNP output is
possible.
