The 140CPU53414B is a Modicon Quantum processor for use with ProWorx 32 or Concept software. It includes a mathematical coprocessor and an internal memory of 2972 kB RAM. This unit is functionally identical to the non-B version, with some considerations. If you are using the CPU in a Hot Standby setup, you must use with two non-A, two A, or two B versions. The B version also requires a new flash exec, which is not interchangeable with the A and non-A flash executives.  These products are manufactured in France and are designed for Material handling, packaging, and textile machines usage. They come with a 2-year warranty from MRO Electric. We also carry CPUs from other manufacturers such as Modicon and ABB.

Any combination of NOM, NOC, NOE, PTQ, PDP, MV1 or MMS modules can be used to but a max of 6 at any time.  The Modicon 140CPU53414B comes with a key switch.  The CPU module 140CPU53414B can support up to 3 modbus network.

How to use a Modicon 140CPU53414B

When starting a system that is powered by summable power supplies, the appropriate way to do that is to introduce both supplies in the rack. This must be done in an unpowered state. After both unpowered supplies are installed in the rack you can then apply power to each supply.  You do not have to turn them on at the same time. This is because the summable supply is independent of the total rack load.
