Description
【A-B 889D-R4ACDE-2】
The A-B 889D-R4ACDE-2 is an analog input module designed by Allen-Bradley, a leading automation and control company.
This module is primarily used to convert real-world physical quantities (like temperature, pressure, or voltage) into electrical signals that can be understood by a programmable logic controller (PLC) or other digital systems.
Key Features and Specifications
1. Analog Input Channels: The exact number of channels will depend on the specific configuration, but typically, it can range from a few to several dozen.
2. Input Range: This module can handle a wide range of input voltages, such as 0-5V, 0-10V, or 4-20mA.
3. Resolution: The resolution determines the accuracy of the analog-to-digital conversion. Higher resolution means more precise measurements.
4. Isolation: Many analog input modules, including the 889D, have isolation between the input and output circuits to protect the PLC from electrical noise or faults.
5. Sampling Rate: This specifies how often the module samples the analog input signal. A higher sampling rate provides more data points per unit of time.
