A-2 Specifications
ArmorPoint DeviceNet Adapters - 1738-ADN12, -ADN18, -ADN18P, and -ADNX
DeviceNet Power Specifications
Power Supply
Note: In order to comply with CE Low Voltage Directives (LVD), you must use either a NEC Class
2, a Safety Extra Low Voltage (SELV) or a Protected Extra Low Voltage (PELV) power supply to
power this adapter. A SELV supply cannot exceed 30V rms, 42.4V peak or 60V dc under normal
conditions and under single fault conditions. A PELV supply has the same rating and is
connected to protected earth.
Input Voltage Rating 24V dc nominal
DeviceNet Input Voltage Range 11-25V dc DeviceNet specification
Input Overvoltage Protection Reverse polarity protected
DeviceNet Power Requirements 24V dc (+4% = 25V dc) @ 30 mA maximum
