Information About 1769-OF8C
The 1769-OF8C belongs to the 1769 Compact I/O family and integrates seamlessly with CompactLogix 1769/1768 controllers and MicroLogix 1500 systems. It provides eight single-ended current outputs with a configurable range of 0–20 mA or 4–20 mA, supporting actual output ranges of 0–21 mA or 3.2–21 mA. Each channel features 16-bit resolution, offering 0.323 µA/bit precision, with a conversion rate of 5 ms across all channels. The module’s accuracy is rated at ±0.35% full scale at 25 °C, with step response times below 2.9 ms for fast loop control. It incorporates open-loop, short-circuit, and overvoltage protection, as well as per-channel diagnostics that report under/over-range and wiring issues. Installation uses an integral removable terminal block with finger-safe protection for copper wiring (22–14 AWG solid, 22–16 AWG stranded). The module draws 145 mA at 5V DC and 185 mA at 24V DC from the backplane, with heat dissipation of 2.69 W. Compact and lightweight at 0.28 kg, the 1769-OF8C is suitable for panel-mounted CompactLogix or expansion racks in distributed systems.
Key Features:
- Design: Compact 8-channel analog output module for current-only applications.
- Output Range: Configurable for 0–20 mA or 4–20 mA; extended range 0–21 mA or 3.2–21 mA.
- Resolution: 16-bit precision with 0.323 µA/bit resolution.
- Performance: 5 ms conversion rate for all channels; <2.9 ms step response to 63% output.
- Accuracy: ±0.35% full scale at 25 °C.
- Diagnostics: Per-channel reporting for open wires, over/under-range, and load resistance issues.
- Protection: Integrated open-circuit, short-circuit, and overvoltage safeguards.
- Compatibility: Works with CompactLogix 1769/1768 and MicroLogix 1500 controllers.
The 1769-OF8C provides accurate, reliable, and protected analog current outputs for industrial control and automation systems.
