Information About 1769-OF2

The 1769-OF2 belongs to the Allen-Bradley Compact I/O family and is designed for precise analog output applications in industrial automation. Each channel uses a sigma-delta digital-to-analog converter, providing resolutions up to 14 bits (unipolar) or 14 bits plus sign (bipolar). It supports full-scale voltage ranges from ±10.5V DC to 0.5–5.25V DC and current ranges up to 21 mA, ensuring accurate signal generation. With a conversion rate of 2.5 ms and a step response of 2.9 ms, the module delivers fast and stable outputs suitable for controlling modulating devices, re-transmitting analog signals, or feeding panel meters and data loggers. The module consumes 120 mA at 5.1V DC with a heat dissipation of 2.36 W, requiring no calibration as accuracy is guaranteed by its hardware design. Compact and efficient, it supports installation up to eight modules away from the system power supply.
