Interface condition of Alarm Input Terminal
Non-voltage, relay “a” contact input
Or non-contact, semiconductor “a” contact input
Or NPN open-collector input
Active low level, latch/momentary(500 ms or more)
Circuit current 1 mA at low level, applied voltage
5 V at high level.
Examples of Sensor Devices
Infrared sensor, door sensor, metal sensor
manual switch, etc.
Interface condition of Alarm Output Terminal
Equivalent to NPN open-collector outpuut
(The output logic is set by the Setup Tool software)
Allowable input voltage: 12 V DC or less
Allowable current drain: 300 mA or less
Momentary(2-5000 msec)output
(The time is set by the Setup Tool software)
Examples of Alarm device
Alarm, indicator, light, buzzer, etc.
Note:
The types of relay contact mechanisms are expressed as “a” contact, “b”
contact, “c” contact, etc.
“a” contact: The contact is normally”Open” and is “Closed” when an event
occurs.
“b” contact: The contact is normally”Closed” and is “Open” when an event
occurs.
“c” contact: The contact status is inverted when an occurs.
