The 1756-IF4FXOF2F is a ControlLogix discrete high-speed analog I/O module.

It has four (4) high speed, sub-millisecond, differential inputs and is compatible with input signals ranging from ± 10V 0…. .10V 0… .5V 0… .20 mA.

It also has two high-speed voltage or current outputs with an output signal range of ± 10V 0…. .20 mA.

About the 1756-IF4FXOF2F

The Allen-Bradley 1756-IF4FXOF2F is an analog combo I/O module.

The module is part of the ControlLogix system and is compatible with the 1756 ControlLogix chassis, which requires the 1756-TBS6H or 1756-TBCH removable terminal block enclosure (RTB).

The module has four sub-millisecond high-speed differential inputs and two high-speed voltage or current outputs.

The module has a display that shows the module’s health and operating status (e.g., calibration mode).

The 1756-IF4FXOF2F has input ranges of +/-10 volts, 0 to 10 volts, 0 to 5 volts, and 0 to 20 milliamps, and displays over-range when the module is out of these ranges.

Overvoltage protection is 30 volts DC and 8 volts AC/DC. Its open circuit detection is a positive full scale reading within 1 second.

The module has an output range of +/-10 volts, 0 to 20 milliamps, and short-circuit protection, limiting the electronic current to 21 milliamps or less.

It also has 24-volt DC overvoltage protection and open-circuit detection, but is limited to current outputs only (note that outputs must be set to greater than 0.1 mA).

The 1756-IF4FXOF2F has backplane voltage and current ratings of 375 milliamps (at 5.1 volts DC) and 100 milliamps (at 24 volts DC).

The analog inputs and outputs are rated at -10 to 10 volts and 4 to 20 mA, respectively.

Module power consumption is 4.3 watts with 4.3 watts of voltage dissipation and 4.7 watts of current dissipation.

Thermal dissipation is 14.66 BTU/hr for voltage and 16.02 BTU/hr for current.

Current consumption is 375 mA at 5.1 volts and 100 mA at 24 volts.

It has a scan time update cycle of 300us minutes with sub-millisecond channel scanning and multi-module synchronized sampling.

The Allen-Bradley 1756-IF4FXOF2F is a ControlLogix high-speed analog combo module.

The module features four (4) high-speed, sub-millisecond differential inputs that accept ± 10V, 0 to 10V, 0 to 5V, and 0 to 20 mA signal ranges.

Each analog input channel has integrated over- and under-range indication. It is also equipped with two (2) high speed voltage or current output channels with output ranges of ± 10V and 0 to 20 mA.
