Omron H7BX

H7BX

• Inrush current generated by turning ON or OFF the power supply
may deteriorate contacts in the power supply circuit. Turn ON or
OFF using a device with a rated current of 10 A or higher.
• Input signals may be accepted, not accepted, or unstable for the
following time when the power supply is turned ON or OFF. Set the
system to allow leeway in the timing of input signals.
• This H7BX always compares the count value with the set value.
Thus, if you change the set value during operation, please
remember that the output will turn ON when the set value becomes
equal to the count value.
• With the factory setting, the output will turn ON when power is
supplied to the H7BX because the set value and count value are
both zero. While resetting, however, the output stays OFF.
• Non-volatile memory is used as memory when the power is
interrupted. The write life of the Non-volatile memory is 100,000
writes. The Non-volatile memory is written when settings are
changed, or the power is tuned OFF.
• Water resistance will be lost if the front sheet is peeled off or torn.
Do not use the H7BX if the front sheet is missing or torn.
• Abide by all local ordinances and regulations when disposing of the
H7BX.
• External Power Supply
Reduce the load current as shown in the diagram on the right
according to the power supply voltage if a DC power supply is used
for models specified for 24 VAC/12 to 24 VDC.
