Specifications
Technical Specifications - 1786-RPA/B
Attribute 1786-RPA/B
Power consumption, max 16.8 W
Power dissipation, max 8.8 W
Input voltage rating, max 700 mA @ 24V DC, Class 2/SELV (1)
(1) For applications within the U.S., use a power supply that is appropriately certified as Class 2 per the
definition in the National Electrical Code, ANSI/NFPA 70, Article 725. For applications outside the
U.S., use a power supply with safety extra low voltage (SELV) or protected extra low voltage (PELV)
output. A power supply with SELV or PELV output is built with appropriate isolation to withstand single
fault conditions. The output cannot exceed 30V rms, 42.4V peak, or 60V DC under fault conditions.
Input voltage range 18…36V DC
