Modicon Quantum Overview: Power Supplies, CPUs, I/O Modules

The Modicon Quantum system is a special purpose computing system with digital processing capabilities. Modicon Quantum is designed for real-time control in industrial and manufacturing applications in a module, expandable architecture employing the following modules.

–          Power Supply

–          CPU

–          I/O

–          I/O Network Interface

–          Intelligent/Special Purpose I/O

–          Simulator (XSM)

–          Battery

–          Backplanes

–          CableFast Cabling

Quantum Power Supplies are used to supply system power to all modules inserted into the backplane, including CPU modules, Interface modules, and I/O modules. Depending upon the system configuration, the option exists of using the power supply in three different modes. The three modes are:

–          Standalone: For 3A, 8A, or 11A configurations that do not require fault tolerant or redundant capabilities.

–          Standalone Summable: For configurations consuming more than the rated current of one supply, two summing power supplies can be installed on the same backplane.

–          Redundant: For configurations requiring power for uninterrupted system operation. Two redundant power supplies are required for redundancy.

The Quantum CPU is a module residing on the Quantum local I/O backplane. The CPU is a digitally operating electronic system, which uses a programmable memory for the internal storage of user interactions. These instructions are used to implement specific functions such as logic, process sequencing, timing, coupling, and arithmetic. These instructions allow control through digital and analog outputs, for various types of machines and processes.  The Quantum CPU serves as a bus master controlling the local, remote, and distributed I/O of the Quantum system.

Quantum I/O modules are electrical signal converters that convert signals to and from field devices to a signal level and format, which can be processed by the CPU such as limit switches, proximity switches, temperature sensors, solenoids, and valve actuators. All I/O modules are optically isolated to the bus, ensuring safe and trouble-free operation. All I/O modules are also software configurable.
