1746-OBP16 | Allen-Bradley | SLC 500 Digital DC Output Module

Description

The 1746-OBP16 is a digital DC output module from Allen-Bradley’s SLC 500 product line, designed for industrial automation control systems. It features 16 output points with a operating voltage range of 10-50V DC. Key electrical specifications include a 5V backplane current draw of 280mA, with per-output nominal current ratings of 0.5A at 30 degrees Celsius and 0.25A at 60 degrees Celsius; total module current is rated 8A at 30 degrees Celsius and 4A at 60 degrees Celsius. The module supports a 3A current surge lasting 10ms, repeatable every 1 second at 30 degrees Celsius or every 2 seconds at 60 degrees Celsius. It provides 1500V AC voltage isolation between the backplane and outputs, with a total heat dissipation of 7.6W. Operating environmental parameters cover a temperature range of 0-60 degrees Celsius, relative humidity of 5%-95% non-condensing, resistance to 30g operational shock, and 2.5g operational vibration across 57-200Hz. The module carries certifications including UL-A196, CSA, and C-UL Class I, Division 2 for hazardous location use, making it suitable for demanding industrial control applications requiring reliable DC output switching.
