MITSUBISHI A series

MELSEC-A

AnCPU is suitable for simple systems up to large scale systems

When used for large systems with A4UCPU, 4,096 I/O points and program memory capacity of 120k steps are supported.
Systems of an even higher processing capacity can be built using A3A, A3U or A4UCPU instead.
Systems can easily be expanded to a larger scale by utilizing the network, since A2U, A3U, A4UCPU are compatible with the MELSECECNET/10.

*: Production was terminated in September 2006.

MELSEC-QnA

QnACPU features a superior performance and large capacity to support any type of system

When used for large systems, 4,096 I/O points, a program memory capacity of 124k steps and expansions up to 7 levels are supported.
When many types of special function units are used or when a large number of processes are controlled designs and changes can be implemented quickly through the distribution of tasks among programs.
Adjustments and changes in the field, as well as remote monitoring, can be performed simultaneously when the centralized administration of a distributed system is required, or when administration is required in the field.
Existing systems can be upgraded to systems with an accelerated processing speed and increased functionality of the AnCPU system, simply by replacing the sequencer CPU and some special function units.

*: Production was terminated in September 2006.

MELSEC-Q4AR

Q4ARCPU redundant PC system

This system is based on the existing system that was configured with a sequencer CPU, which had been enhanced with the redundancy of a power supply, CPU and network, in pursuit of high reliability. It is also a system that made it possible to accelerate the integer calculation process of the CPU and perform PID control.

Redundant PC system
The system is intended for control applications that require high reliability and is designed for continuous operations without suspending any arithmetic operations, even when a CPU unit, network or power supply fails.
Independent system of Q4ARCPU
Q4ARCPU used for the redundant PC system can also be used as an independent CPU for the QnA series.

*: Production was terminated in September 2008.

MELSEC-AnS

AnSCPU saves space and features a superior cost performance

Compact dimensions provide greater freedom for installation.
The adoption of A2USHCPU-S1 improves the processing capacity of systems.
Systems can easily be expanded to a larger scale by utilizing the network, since A2US and A2USHCPU-S1 are compatible with MELSECECNET/10.

*: Production was terminated in September 2014.

MELSEC-QnAS

QnASCPU features a greater number of functions, saves space and features a superior cost performance

Compact dimensions provide greater freedom for installation.
When many types of special function units are used or when a large number of processes are controlled, designs and changes can be implemented quickly through the distribution of tasks among programs.
Adjustments and changes in the field, as well as remote monitoring, can be performed simultaneously when centralized administration of a distributed system is required, or when administration is required in the field.
Existing systems can be upgraded to systems with an accelerated processing speed and increased functionality of the AnSCPU system, simply by replacing the sequencer CPU and some special function units.

*: Production was terminated in September 2014.

MELSEC-A0J2H

A compact I/O unit can be incorporated to suit a system

32 points of dedicated input units, 24 points of dedicated output units, as well as 28 and 56 points of I/O mixed units can be combined and incorporated into a system.
Photocoupler insulation has been used for all units.
The operational status can be verified through the LED displays.
Maintenance work is easy with the terminal block connectors.
Installation can be performed with thin units that save space (and allow for stacked installations).

*: Production was terminated in September 2008.

MELSEC-A2C

Flexible installations!! Compact sequencer for wire saving units that is optimally suited for distributed controls

A sequencer that dramatically saves space and improves economy is thanks to the development of a compact I/O based on a new concept.
The baseless building block type flexible compact high performance sequencer is the A2CCPU.

*: Production was terminated in September 2006.
