Alarm Channel Configuration
The
AMG5614
provides one bi-directional alarm output / contact closure input.
The alarm input is typically connected to a contact closure switch. An ALARM IN+ input incorporates a
330R pull-up resistor to the in3V3 supply.
The alarm output can receive an on/off signal from an
AMG5613
and is typically used to convey
contact closure status. An alarm output uses a solid-state relay, with a maximum load current of
150mA at 125Vac/dc and Ron < 6.5Ω.
