The Allen-Bradley 1756-OF6CI is an isolated analog output module from the ControlLogix series, featuring six individually isolated current output channels. It offers a resolution of 13 bits across a 0–20 mA range, with a minimum increment of 2.7 µA. The module supports both integer and floating-point communication formats and provides advanced features such as data echo, ramping/rate limiting, clamping/limiting, clamp/limit alarms, and hold for initialization. It requires a removable terminal block (RTB) for installation and offers protection against overvoltage and short circuits, with a maximum output current limited to 21 mA. The 1756-OF6CI is designed for high-precision applications, delivering a module error of less than 0.6% and a fast settling time of under 2 ms to 95% of the final value.
