■General

*The internal circuits are optically isolated from the output. This enables universal application as NPN or PNP transistor.

■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.

■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 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.

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.

H3CR-A

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.
