Product Features
Allen Bradley 1771-IL provides 16 single-ended input channels, or 8 differential input channels. The Differential mode is suitable for high noise environment as the common mode interference will effectively be suppressed.
Allen Bradley 1771-IL has voltage input types is 1-5V DC, 0-5V DC, and -10-10V DC, current input types is 4-20mA, 0-20mA, -20-20mA, these input types covering the mainstream output range of industrial sensors.
Allen Bradley 1771-IL features 12-bit resolution, linearity of ±1 LSB, and accuracy of 0.1% of full scale, ensuring the accuracy of data acquisition. The conversion time is ≤25 milliseconds, meeting real-time control requirements.
Allen Bradley 1771-IL features optical isolation design to prevent external interference and includes overvoltage and overload protection functions, enhancing system reliability.
Each channel includes a LED indicator to indicate whether or not a signal is being input and the module contains diagnostic functions for detecting abnormalities in communication or system hardware.
Product Working Principle
Allen Bradley 1771-IL external analog signal is connected to the module via terminals, and the analog-to-digital converter inside the module converts the analog signal into a digital signal.
Allen Bradley 1771-IL optocoupler isolates the external circuit from the PLC controller to prevent interference; the input signal is filtered by software to reduce noise interference.
Allen Bradley 1771-IL converted digital signals are transmitted via the PLC-5 backplane bus to the controller for program logic processing. The module supports natural binary or BCD scaling formats, facilitating direct data usage.
Product Applications
Allen Bradley 1771-IL is capable of monitoring conveyor belt speed, robot joint positions and packaging machine loads, etc. for the purpose of the automatic regulation and-reverse production process control. In the food, drug and chemistry industry.
In the chemical, food, and pharmaceutical industries, Allen Bradley 1771-IL can monitor reactor temperature, pipeline flow, liquid level height, and other parameters to ensure process stability.
Allen Bradley 1771-IL voltage and current information from power systems or pressure signals from oil and gas pipelines to manage energy distribution and equipment operation.
Allen Bradley 1771-IL can monitor pH levels and turbidity in water treatment or pollutant concentrations in exhaust gas treatment to ensure compliance with environmental protection standards.
