Product details

Overview

The 140CPU43412AC is a Modicon Quantum processor from Schneider Electric built around an 80486 CPU with 896 kB of internal RAM and an onboard mathematical coprocessor, handling 30 input and 32 output words distributed across the network. It carries one Modbus Plus port and two Modbus RS232 serial ports, runs on ProWORX 32 or Concept software, and is certified to UL 508, CSA C22.2 No 142, cUL, FM Class 1 Division 2, and CE.

The 140CPU43412AC is a mature Modicon Quantum processor; it is not listed as obsolete in the current evidence, but as a mature offer it is sourced through distribution and surplus channels — an RFQ confirms current availability and lead time for the exact build code.
