Information About 1756-OF8
The 1756-OF8 belongs to the ControlLogix I/O family and is engineered to deliver accurate analog output for process and motion control. Each of its eight channels offers 15-bit resolution, with ranges of 650 nA/bit in current mode and 320 µV/bit in voltage mode. It supports R-ladder DAC conversion, monotonic with no missing codes, and outputs data in integer or IEEE 32-bit floating-point format. The module achieves a scan time of 8 ms in integer mode and 12 ms in floating-point mode. It includes protections for open circuit, short circuit, and overvoltage conditions. The 1756-TBNH and 1756-TBSH removable terminal blocks provide flexible wiring options with support for shielded or unshielded copper conductors. The 1756-OF8 features 250V reinforced isolation (tested at 1350V AC for 2 seconds) between the output channels and the backplane, enhancing system safety. Its operational accuracy is rated at ±0.15% in voltage mode and ±0.3% in current mode, with offset and gain drift compensation across temperature. Designed for harsh industrial conditions, it withstands 30G shock, 2G vibration, and operates reliably in environments between 0–60 °C.
Key Features:
- Design: 8-channel analog output module for ControlLogix systems.
- Output Ranges: Configurable for ±10 VDC or 0–20 mA analog signals.
- Resolution: 15-bit output with precise step sizes (650 nA/bit current, 320 µV/bit voltage).
- Performance: Fast scan time – 8 ms (integer), 12 ms (floating point).
- Data Formats: Supports integer (2’s complement) and IEEE 32-bit floating point.
- Protection: Built-in open-circuit, short-circuit, and overvoltage protection.
- Isolation: 250V reinforced isolation (1350V AC tested) between outputs and backplane.
- Durability: Operates from 0–60 °C with 30G shock and 2G vibration resistance.
The 1756-OF8 delivers reliable, accurate, and flexible analog output control for demanding industrial automation and process applications.
