【英文介绍】

The Allen-Bradley 1756-IF4FXOF2F is an analog composite I/O module. The module belongs to the ControlLogix system, which is compatible with the 1756 ControlLogix chassis and requires a 1756-TBS6H or 1756-TBCH detachable terminal housing (RTB). The module has 4 high-speed submillisecond differential inputs and 2 high-speed voltage or current outputs. The module has a display that shows the module health and operating status, such as calibration mode. The 1756-IF4FXOF2F has input ranges of +/-10 volts, 0 to 10 volts, 0 to 5 volts, and 0 to 20 MA, and displays an overrange indication when the module exceeds these ranges. The overvoltage protection voltage is 30 volts DC and the current is 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 mA, with short circuit protection and electronic current limitation of 21 MA or less. It also has overvoltage protection and open circuit detection for 24 volts DC, but only for current output (note that the output must be set to greater than 0.1 mA). The backplane of the 1756-IF4FXOF2F is rated at 375 mA (5.1 volts DC) and 100 MA (24 volts DC), with analog inputs and outputs rated at -10 to 10 volts and 4 to 20 mA. The module has a power consumption of 4.3 watts, a voltage dissipation of 4.3 watts, and a current dissipation of 4.7 watts. The heat dissipation of voltage and current is 14.66 BTU/ hour and 16.02 BTU/ hour, respectively. It has a current consumption of 375 mah at 5.1 volts and 100 mah at 24 volts. It also has an update cycle with a 300-minute scan time and features sub-millisecond channel scanning and synchronous sampling across multiple modules.

The Allen-Bradley 1756-IF4FXOF2F is a ControlLogix high-speed analog combination module. The module features four (4) high-speed sub-millisecond differential inputs compatible to receive 10V, 0 to 10V, 0 to 5V, and 0 to 20 mA ± signal ranges. It integrates overrange and underrange 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 input channel of the module converts the received analog signal by successive approximation with a resolution of 14 bits (±10.5V) and 12 bits (21 mA). It has a repeatability of ±1 least significant bit (LSB) and requires a calibration interval of 12 months. Analog inputs are suitable for measuring simulated process variables such as flow, level, pressure, temperature, viscosity, pH, turbidity, velocity, and many other process variables.
