Overview
The Allen-Bradley 1769-OF2 Series B is a single-slot, compact analog output module designed for Compact I/O platforms. This module delivers precise voltage and current analog signals for industrial automation, motion control, and process control applications. Built for compatibility with CompactLogix and MicroLogix 1500 controllers, the 1769-OF2 offers a factory-calibrated design that eliminates field calibration and reduces commissioning time.
Key Features
- Two Single-Ended Analog Output Channels: Each channel operates independently and can be configured as either voltage or current output.
- Multiple Output Ranges: Supports ±10V DC, 0–10V DC, 0–5V DC, 1–5V DC, 0–20 mA, and 4–20 mA signals for flexible application design.
- Sigma-Delta DAC Technology: 14-bit resolution (unipolar) or 14-bit plus sign (bipolar) ensures high-accuracy signal generation.
- Fast Response: 2.5 ms conversion rate and 2.9 ms step response for modulating device control and signal re-transmission.
- Factory-Calibrated: No manual calibration required; accuracy is ensured by hardware design at manufacture.
- DIN Rail Mounting: Includes upper and lower DIN rail latches and tongue-and-groove slots for secure installation. Removable terminal block (RTB) for simplified wiring.
