Product Details

The Schneider 140CPU11302C conformal coated processor module is the core control unit for Modicon Quantum PLC systems deployed in moist, dusty and corrosive industrial environments. This modicon quantum cpu module adopts 80186 processor running at 20MHz clock frequency, equipped with 109kB internal RAM and no built-in floating-point coprocessor. The PCB circuit board is treated with conformal coating, which protects internal electronic components against moisture, dust and corrosive gas, maintaining stable long-term operation in harsh plant conditions. It supports LL984 logic program execution, the scan time for 1K boolean instructions ranges from 0.3ms to 1.4ms. Two communication ports are integrated on the module, one RS232 Modbus serial port and one Modbus Plus port, supporting data exchange with local I/O modules, touch screens and other field automation equipment. A 250ms watchdog timer is configured to detect abnormal program execution and trigger safety protection actions automatically. It can handle up to 64 input and 64 output local words, 64I/64O remote words and 30I/32O distributed words. Programming can be completed via ProWORX 32 or Concept software platform. This CPU supports direct plug-in installation on Quantum backplane rack and works with full series of Quantum I/O, power supply and communication modules to build complete industrial control systems. This original Schneider product was discontinued on May 31,2015 and end-of-service on Dec 31,2025, widely stocked as spare replacement parts for maintenance and upgrade of legacy industrial automation systems. It is widely used in power, petrochemical, metallurgy, water treatment and manufacturing plants as the core controller for medium-scale Modicon Quantum automation racks in harsh industrial environments.
