Allen-Bradley 1756-0F8 Analog Output Module

Description

The Allen-Bradley 1756-OF8 Analog Output Module is an 8-channel analog output unit designed for the ControlLogix chassis, compatible with any slot in the enclosure. It supports configurable voltage or current outputs, with ranges of ±10V DC, 0 to 20 mA, or 4 to 20 mA, making it suitable for industrial automation applications such as driving valves, frequency converters, and actuators. Key performance specifications include 15-bit signal resolution at 21 mA and 10.4V, 0.05% calibration accuracy, and a 2 millisecond output signal settling time. The module offers robust protection features, including overvoltage protection and short-circuit protection via electronic current limiting to 21 mA or lower, plus built-in circuit detection capabilities. It provides electrical isolation of 250V AC between channels and 500V AC between the module and backplane, with a per-channel conversion rate of 1 ms and total conversion time of ≤8 ms. Power requirements include a backplane current draw of 210 mA at 24V DC and 150 mA at 5.1V DC, with a total rated power of 5.8 watts. Operating temperature ranges from 0 degrees Celsius to 60 degrees Celsius, with storage temperature from -40 degrees Celsius to 85 degrees Celsius, and temperature drift of ±50 ppm per degree Celsius.
