Information About 1771-OFE2
The 1771-OFE2 is part of the Allen-Bradley 1771 classic I/O series and occupies a single slot in any 1771 I/O chassis, functioning as a local or remote I/O module for PLC-5 controllers. Each of its four output channels is individually isolated, allowing independent 4–20 mA current-loop control for actuators, drives, valves, and process instrumentation. This module supports both Natural Binary and BCD data formats, enabling scalable analog output control and integration with PID instructions. Built with a conformal-coated design, onboard diagnostics, and LED indicators, the 1771-OFE2 is engineered to provide stable, reliable analog output performance in industrial environments.
Key Features
- Four Isolated Analog Outputs: Individually isolated 4–20 mA channels support independent current-loop applications.
- 12-Bit Digital Resolution: Ensures accurate conversion from digital commands to analog current output.
- Flexible Data Formatting: Supports Natural Binary and BCD scaling up to ±9999 engineering units.
- Single-Slot Installation: Fits any 1771 I/O chassis and connects using the 1771-WC wiring arm.
- Integrated Diagnostics: LED indicators support power and fault monitoring during operation.
- Industrial Isolation Ratings: Channels rated for 1000 V differential isolation for field protection.
- Fast Update and DAC Performance: Offers quick channel update times for responsive control loops.
- Conformal Coating: Added protection for harsh or high-moisture environments.
The 1771-OFE2 delivers the reliability and precision required for stable analog current-loop control in process and automation systems.
