Allen-Bradley 1769-OF2 NSNBC01 Programmable Logic Controller Module

The Allen-Bradley 1769-OF2 NSNBC01 is a two-channel analog output module for the Compact I/O 1769 family that provides precise control signals to field devices from a 24V DC supply. Each channel can output either a voltage signal (unipolar 0–10V, 0–5V, 1–5V or bipolar ±10V) or a current signal (0–20 mA or 4–20 mA). The module uses a 14-bit resolution per channel with delta-sigma conversion and a maximum conversion time of 2.5 ms for all channels. It supports output loading of >1 kΩ for voltage outputs and 0–500 Ω for current outputs, with a typical heat dissipation of up to 2.63 W, and draws about 120 mA from the 5.1V logic supply and the 24V field supply. This makes it well-suited for integrating into CompactLogix control systems to drive analog actuators, valves, and instrumentation in process and automation applications.
