analog input module

The Schneider 140CPU43412A is a Modicon Quantum CPU module for the Modicon Quantum PLC platform. Based on the Schneider naming convention, the "140" prefix indicates the Modicon Quantum product family, "CPU" indicates the central processing unit, and "43412A" identifies the specific memory, performance, and communication configuration. It serves as the central processing unit for the Quantum PLC rack, executing control programs and managing communication with I/O modules and supervisory systems.

The Schneider TM3AI8 is an 8-channel analog input expansion module from the Modicon TM3 range. Its core function is to convert analog signals from field sensors—such as temperature, pressure, or flow transmitters—into digital values that Modicon M221, M241, M251, and M262 logic controllers can process . The module supports both voltage and current input types.
