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:
- Channel Capacity: Provides eight (8) isolated analog output channels configurable for voltage or current signals.
- Output Ranges: Supports voltage outputs of -10 to 10V, 0 to 10V, 0 to 5V, and current outputs of 0–20 mA or 4–20 mA.
- Resolution and Format: Delivers 15–16-bit resolution with IEEE 32-bit floating-point data format for high accuracy.
- Conversion Method: Uses R-Ladder DAC with monotonic conversion and no missing codes for precise signal control.
- Protection Functions: Includes open-circuit detection (current), short-circuit detection (voltage), and ±30V DC overvoltage protection.
- Electrical Ratings: Backplane current draw of 200 mA at 5.1V DC and 275–400 mA at 24V DC with a maximum power dissipation of 6.5W.
- Isolation: Provides 50V continuous isolation voltage, tested up to 1500V AC/2300V AC for 60 seconds for channel-to-channel and backplane safety.
- Environmental Reliability: Operates in 0–60 °C with 5–95% non-condensing humidity, shock tested to 30G, ensuring rugged industrial performance.
The 1756-OF8I delivers the reliability and precision required for complex process control and motion applications in industrial automation systems.
