Allen-Bradley 1769-OF2 Two-Channel Analog Output Module

Allen-Bradley 1769-OF2 is a CompactLogix two-channel analog output module that provides two single-ended outputs for voltage or current signals within a 1769 Compact I/O chassis, suitable for local or distributed I/O in 1769 CompactLogix systems such as L3x, 5370, or Compact GuardLogix 5370 controllers. Each channel can be configured to deliver either voltage (ranges including 0–10 V, ±10 V, 0–5 V, or 1–5 V) or current (0–20 mA or 4–20 mA) with a 14-bit conversion resolution, and the device supports a maximum conversion rate of 2.5 ms across both channels. Electrical characteristics specify a current output load of 0–500 Ω and a voltage output load greater than 1 kΩ at 10 V, with the module using a delta-sigma analog conversion method. Power draw is listed as 120 mA when powered from either 5.1 V or 24 V supply rails, reflecting its backplane-driven power in typical Compact I/O configurations. The 1769-OF2 is designed for precise setpoint and control tasks in process and automation applications, such as valve positioning, motor speed control, or level and flow regulation, and it is commonly deployed as local or distributed I/O within a CompactLogix system. In practice, it is deployed as a compact, two-channel output solution for applications requiring reliable voltage or current signaling from a small, field-installable module within a 1769-compatible rack.
