The Allen Bradley 1756-OF6CI 8-Point Analog DC Output Module is a current loop Analog DC 8-point output module in the controlLogix family of high speed I/O modules, which provides shared high-speed output signals between multiple ControlLogix Controllers. This module is installed on the Controller chassis and requires a removable terminal block or a fused interface module (IFM) for installation and all field-side wiring. The 1756-OF6CI has 6 individually isolated 13-bits outputs, with 0 to 21 milliAmpere low signal and high signal user count outputs. This module draws 250 milli-Ampere chassis current at 5.1 Volt DC and 225 milli-Ampere currents at 24 volt DC, and it has a total backplane power of 6.7 Watts at 0 to 550 Ohms load and 8.5 Watts backplane power a 551 to 1000 Ohms load. The 1756-OF6CI unlike most 1756 I/O modules do not have open circuit detection capability, but it provides 24 Volt DC overvoltage protection and also provides short-circuit protection by electronically limiting the output current to 21 milli-Ampere or less. This module requires field calibration once every 6 months of use, and it can be calibrated to an accuracy of 0.01% over 4 to 21 milli-Ampere operating range.
It has maximum offset drift of 1 micro-Ampere per degree Celsius, with a maximum gain drift of 100ppm per degree Celsius, and this module produces a high-speed output signal with less than 0.6% module error. It has a maximum scan time of 25 milliseconds for floating point data format, and 10 milliseconds for integer data format, and it provides easy conversion between data format via R-Ladder DAC converter. The 1756-OF6CI has 250 Volt isolation voltage between the output channel to the backplane, using basic insulation tested at 1350 volt AC for 2 seconds. It is electronically keyed to the chassis via digital control to ensure precision, and it is keyed to the removable terminal block (RTB) via mechanical mode. It is designated T4A North America, and T4 IEC rated temperature code, and it has a functioning temperature limit of 0 to 60 degree Celsius (32 to 140 degree Fahrenheit) at non-condensing 5% to 95% relative humidity range. The 1756-OF6CI has no rated enclosure, and it is UL, CSA, CE, EX, C-TICK, FM, and KC certified.

About 1756-OF6CI
The Allen-Bradley 1756-OF6CI output module is an isolated analog output module that is part of the 1756 series of ControlLogix systems. This analog output module is widely known in the industry for providing a high level of noise immunity. Another important feature of the physical structure of the model is that it can be removed from or installed in the chassis under power, and this means it is not necessary to power down the chassis to install this module. One benefit of this feature is that it enhances the availability of the overall control system since there is no disruption to the rest of the machine while the model is being removed or inserted. The Allen-Bradley 1756-OF6CI isolated analog output module comes with a module fault reporting process that consists of a status indicator light that alerts the users when a fault has occurred by lighting up or flashing. This status indicator enables the users to determine when the module has been affected by a fault and requires intervention.
The Allen-Bradley 1756-OF6CI isolated analog output module needs to be initially configured by adding one of the available data formats. This data format will determine the data exchange rated between the main controller and the input and output module. Some of the available data formats are the integer format and the floating-point format. The integer format uses a 16-bit sign format and the floating-point uses a 32-bit floating-point format. It is widely recommended to use the floating-point data format for most applications since it is simpler to use. The Allen-Bradley 1756-OF6CI isolated analog output module has a maximum current rating of 21 milliamps with a resolution of 2.7 microamps.
