A-B 1747-L541
The A-B 1747-L541 module is an analog input module from Rockwell Automation under the Allen-Bradley brand, primarily used in the SLC 500 series programmable logic controllers (PLCS). It is responsible for collecting the analog signal of the field equipment (su
ch as temperature, pressure, etc.) and converting it into a digital signal that the PLC can process.
Product name and meaning
A-b: Short for Allen-Bradley, A brand of Rockwell Automation.
1747-L541: Model number of the module, where 1747 stands for SLC 500 series and L541 stands for 4-channel analog input.
Product description
The main functions of the 1747-L541 module are:
