Alarm Input/Output Signal

TOP

Alarm Input Signal

Connect to sensors such as infrared sensors, door sensors, metal sensors and manual switches.

To prevent noise from entering the internal circuit, supply non-voltage contact signal to the alarm input signal.

Memo

You can configure whether to set the alarm when the contact is short (MAKE) or open (BREAK) in the [Alarm] page of the [Advanced Settings] page.

Apply such that the alarm signal continues for at least 500 ms. The alarm signal may not be recognized if it is less than 500 ms.

Note

Do not supply voltage.

Low-level terminal current:

1 mA and below

High-level terminal voltage:

DC 3.3 V

Alarm Output Signal

Connect to alarm devices such as alarm, indicator, light or buzzer.

Alarm output signal is an open collector output insulated with photo coupler.

Memo

You can select whether to set the contact to short (Make) or open (Break) during an alarm in the [Alarm] page of the [Advanced Settings] page.

Note

As this terminal is polarized, be sure to connect it such that the voltage of the OUTPUT output is higher than that of the COM output.

It will be damaged if reverse voltage is supplied.
