Description
The code “1771-ACNR” refers to an Allen-Bradley 1771-ACNR Analog Output Module used in industrial automation applications. Here’s a breakdown of the product details:
Product Name:
- Allen-Bradley 1771-ACNR Analog Output Module (exact name may vary depending on model revision)
Product Description:
The 1771-ACNR is a module within the Allen-Bradley 1771 I/O (Input/Output) system. This system is designed for expanding the output capabilities of compatible Rockwell Automation controllers. Specifically, the 1771-ACNR focuses on analog outputs.
Product Function:
The 1771-ACNR module receives digital control signals from the connected PLC (Programmable Logic Controller) and converts them into proportional analog voltage or current signals. These analog signals are then used to control various industrial equipment like:
- Variable speed drives for AC motors (e.g., controlling motor speed)
- Solenoid valves (e.g., regulating fluid flow)
- Analog indicators (e.g., displaying process values)
Product Parameters and Specifications (Refer to Rockwell Automation website or datasheet for details):
Exact specifications may vary depending on the specific model revision of the 1771-ACNR module. However, some typical parameters might include:
- Number of Output Channels: The number of analog output channels the module can provide (e.g., 2 channels, 4 channels).
- Output Signal Type: The type of analog signal the module can generate (e.g., voltage output range, current output range).
- Resolution: The level of detail in which the digital signal is converted into an analog voltage or current level (e.g., 12-bit resolution, 16-bit resolution).
- Output Current/Voltage Limits: The maximum and minimum voltage or current levels the module can output.
- Output Update Rate: The speed at which the module updates the analog output signal based on the digital input from the PLC.
