Specifications of the alarm output
Open collector output
Voltage that can be applied to the terminal : 0 to 20 V
Pull-in current :
Maximum 50 mA when the output transistor is
saturated (output terminal voltage is 1 V or less).
Output terminal voltage x pull-in current < 50 mV
when the output transistor is non-saturated.
DATA :
10BASE-T/100BASE-TX (RJ-45 8-pin Modular jack)
