H3CR-A
DIN 48 x 48-mm State-of-the-art
Multifunctional Timer
• A wider power supply range reduces the number of timer models kept in stock.
• A wide range of applications through six or four operating
modes.
• Reduced power consumption.
(Except for H3CR-A8E)
• Enables easy sequence checks through instantaneous outputs
for a zero set value at any time range.
• Length, when panel-mounted with a Socket, of 80 mm or less.
• Time Setting Rings enable consistent settings and limit the setting range.
• Panel Covers enable various panel designs.
• PNP input models available.
• Rich variety of inputs: Start, reset, and gate functions (11-pin
models and -AP models)

The minimum power-opening time (“Rt”) is 0.1 s.
The minimum input pulse width (for start, reset) is 0.05 s.
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.

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.
Signal OFF-delay operation (D mode) can be effectively used to keep
a load operating for a certain period. For example, this function

period after the lamp or heater is switched OFF.

Precautions (H3CR-A)
■ Power Supplies
■ Input/Output
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.

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.

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.
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).

Since the input circuit and the power supply circuit are configured

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.
