H5RA
Operation
Basic Operation
The H5RA is an electronic rotary timer whose control outputs repeatedly turn ON and OFF in a fixed cycle. The H5RA is ideal for controlling
machines that repeatedly perform a fixed cycle, replacing old-fashioned electrified cam timers. The operation pattern and cycle time of each
output can be easily set or changed by programming, providing flexibility and sophistication. Full details on programming are contained in the
H5RA Rotary Timer Operation Manual, available from OMRON.

Control Inputs
The control inputs are signals from such things as pushbuttons or external devices which control the operation of the Rotary Timer.

or recovery.

OUTPUT
MODE
Normally START 1 Starts the timer.
read in
START 2 Starts and, when one cycle
is completed, stops the
timer operation.
Note: The priorities of the START 1 and 2 signals are the same and thus
the timer operates according to the most recent signal. For example,
if the timer is started by START 1 and then detects the trailing edge
of START 2, it stops at the end of the present cycle.
Gate Pauses the timer operation.
RESET Returns the present time
value to 0 and stops the
timer operation.

Function
When this input signal is turned ON, the present time value is reset on
power application.
When it is OFF, the present time value before power failure is retained.
When this input signal is turned ON, the timer starts operating on power
application. When it is ON, the timer waits until the START 1 or START 2
signal is input.
When this input signal is turned ON, the control outputs remain OFF until
either the START signals or the RESET signal is input. When it is OFF, the
control output returns to the status before power failure. This input signal
has no effect while the START at PW.ON signal is turned ON.
The timer starts operating at the leading edge of this input signal. It does not
detect the trailing edge. Therefore, the timer can be continuously operated
by a one-shot input signal.
The timer starts operating at the leading edge of this input signal. After it
has detected the trailing edge, the timer stops when the cycle has been
completed.
The timer pauses at the
leading edge of this input
signal. The control output
signals retain their present
conditions.
The timer returns its
present value to 0 and
stops operating at the
leading edge of this input
signal.
