Basics Features of the MELSEC System Q Base units The Q00JCPU and Q00UJCPU include power supply, CPU and main base unit with five slots. All other CPUs have to be mounted on a main base unit. Additionally one or two power supplies can be mounted and up to twelve modules. Extension base units can be connected to the main base unit via bus cable. The extension base units are available with or without slots for a separate power supply and with slots for up to twelve modules.
Features of the MELSEC System Q Basics High speed program processing CPU types with an additional "H" (like Q12HCPU, Q25HCPU or Q12PHCPU) do a faster processing of the program. The operation time for the LD instruction (load) by the Q02CPU is 79 ns. The same instruction is done in 34 ns by the H type CPU. An universal model PLC CPU increases the processing speed additionally. The operation time of the above mentioned LD instruction takes only 20 ns with the Q03UDCPU and only 9.
Basics Features of the MELSEC System Q Memory In addition to the internal memory (RAM and FlashROM) all CPU types (except Q00(U)JCPU, Q00(U)CPU and Q01(U)CPU) have an extension slot for a RAM or a ROM memory card. The RAM card is protected against data loss with a battery. ROM memory cards are available with capacities up to 32 Mbyte for permanent storage of programs and other data.

Selecting I/O modules Input and output modules 6 Input and output modules 6.1 Selecting I/O modules Triac outputs It is recommended to use triac output modules instead of relay output modules if: ● The outputs should be switched in fast sequence on and off ● A load with high inductance or low power factor should be switched When using relays for these applications, the life of relay contacts is reduced considerably.
Input and output modules Selecting I/O modules Overload protective function Fuses installed in output modules cannot be replaced. They are designed to protect external wiring if the module outputs are shorted. Therefore, output modules may not be protected from a short circuit. If an output module becomes faulty due to any cause other than a short circuit, its fuse may not function.
Selecting I/O modules Input and output modules Number of simultaneously set inputs The number of signals, which can be turned ON simultaneously in an input module, varies according to the input voltage and ambient temperature. The number of inputs, which can be turned ON simultaneously is shown in the following diagrams.
