1756-IF4FXOF2F ALLEN BRADLEY Relay Module
1756-IF4FXOF2F is a high-speed analog combination I/O module from the ControlLogix series under Rockwell Automation. It has four high-speed, sub millisecond differential input channels and two high-speed voltage or current output channels, and is compatible with receiving various signal ranges such as ± 10V, 0 to 10V, 0 to 5V, and 0 to 20mA. It is suitable for precise acquisition and output of analog signals in industrial automation control systems; This module integrates over range and under range indication, overvoltage protection (30V DC), open circuit detection (positive full-scale reading within 1 second), and short circuit protection (electronic current limit ≤ 21mA) functions. It supports 24V DC overvoltage protection and current output open circuit detection (output>0.1mA required), and achieves conversion resolution of 14 bits (± 10.5V) and 12 bits (21mA) through successive approximation method, with a repetition accuracy of ± 1LSB. It has a 300us update cycle and sub millisecond channel scanning capability, and can synchronize cross module sampling to ensure real-time and synchronous signal processing; Its analog output adopts the leakage free R-ladder DAC conversion method, with a resolution of 13 bits (21mA=2.8 µ A/bit) and 14 bits (21.8V=1.3mV/bit). The output signal can be used to control regulating valves, variable frequency drives, and other devices, or retransmitted to indicators, recorders, and other devices. It supports output connections with manual control instructions, arithmetic operations, or PID controllers; In addition, the module is equipped with a display screen that can display health status and operating status in real time (such as calibration mode), with a power consumption of only 4.3 watts. It has a corrugated aluminum reinforced casing with IP30 protection level, supports 35mm DIN rail installation, and has a working temperature range of -10 to 70 ℃ (optional wide temperature -40 to+85 ℃). It is suitable for complex industrial environments such as power plants, chemical plants, and steel plants, and is an ideal choice for high-precision analog signal processing and control in the field of industrial automation.
