About 1756-IF4FXOF2F
Allen Bradley 1756-IF4FXOF2F is an analog combination I/O module. This module belongs to the ControlLogix system and is compatible with the 1756 ControlLogix rack, requiring a 1756-TBS6H or 1756-TBCH detachable terminal block housing (RTB). This module has 4 high-speed sub millisecond differential inputs and 2 high-speed voltage or current outputs. This module has a display screen that displays the health status and operational status of the module (such as calibration mode). The input range of 1756-IF4FXOF2F is+/-10V, 0 to 10V, 0 to 5V, and 0 to 20mA. When the module exceeds these ranges, an over range indication will appear. The overvoltage protection voltage is 30 V DC and the current is 8 V AC/DC. Its open circuit detection is a positive full scale reading within 1 second.
The output range of this module is+/-10 volts, 0 to 20 mA, and it has short circuit protection function, with electronic current limited to 21 mA or less. It also has 24 volt DC overvoltage protection and open circuit detection, but is limited to current output (note that the output must be set to greater than 0.1 milliampere). The backplane voltage and current ratings of 1756-IF4FXOF2F are 375 mA (5.1 V DC) and 100 mA (24 V DC), and the analog input and output voltage and current ratings are -10 to 10 V and 4 to 20 mA. The power consumption of this module is 4.3 watts, voltage consumption is 4.3 watts, and current consumption is 4.7 watts. The thermal dissipation of voltage and current is 14.66 BTU/hour and 16.02 BTU/hour, respectively. Its current draw is 5. 375 mA at 1 volt and 100 mA at 24 volts. It also has an update cycle of 300us minutes of scanning time, as well as sub millisecond channel scanning and synchronous sampling across multiple modules.
Allen Bradley 1756-IF4FXOF2F is a ControlLogix high-speed analog combination module. This module has four (4) high-speed sub millisecond differential inputs and is compatible with receiving ± 10V, 0 to 10V, 0 to 5V, and 0 to 20 mA signal ranges. It has integrated over range and under range indications for each analog input channel. It is also equipped with two (2) high-speed voltages or currents, with an output range of ± 10V and 0 to 20 mA.
The output channel of this module has 13 bit output resolution and 14 bit output resolution within the range of 21 mA=2.8 µ A/bit and 21.8V=1.3 mV/bit. The output channel conversion adopts the R-Ladder DAC conversion method, without code loss. The output analog signals of this module can be used to command the modulation actions of control valves, variable frequency drives, dampers, louvers, signal converters, and sensors. It can also be used to retransmit signals for use by indicators, recorders, and other devices. The analog output of this module can be linked to the control output of manual control commands, arithmetic operations, or proportional integral derivative (PID) controllers.
