Information About 1756-OF8I
The 1756-OF8I belongs to the Allen-Bradley ControlLogix family of I/O modules and is designed for high-performance analog output applications. It supports configurable output ranges of -10 to 10V, 0 to 10V, 0 to 5V, and 0–20 mA or 4–20 mA, all with 15- to 16-bit resolution using IEEE 32-bit floating-point data format. Each channel is fully isolated, providing improved signal integrity and reduced interference across outputs. The module features R-Ladder DAC conversion with monotonic performance, ensuring accurate and stable signal generation without missing codes. It includes built-in open-circuit detection for current outputs, short-circuit detection for voltage outputs, and overvoltage protection up to ±30V DC. With removable terminal blocks (1756-TBNH, 1756-TBSH, 1756-TBCH, 1756-TBS6H), it allows flexible wiring options for system integration. The 1756-OF8I is designed for direct installation into any 1756 ControlLogix chassis, supporting demanding industrial automation environments with reliability and precision.
Key Features:
