44A0131-26-0/2/9-US

44A0131-26-0/2/9-US is a type of controller from the 44A Series of the Allen-Bradley product range. This device is a modular programmable logic controller (PLC) that is designed to suit small-scale applications. The 44A Series includes various I/O types and modules that offer advanced control features to tiny straight-forward applications.

The 44A0131-26-0/2/9-US is a TMR processor type PLC. It is a combination of discrete, analog and specialty I/O, which makes it suitable for a number of applications. The main feature of the controller is the ability to execute TMR control (totally fail-safe monitoring in the PLC) and can be used for low-end applications from control tasks in processing plants, manufacturing and laboratory tests.

The 44A0131-26-0/2/9-US features include communication ports to allow for local and remote access. It also supports different I/O packets for remote I/O from different manufacturers. The integrated clock provides the time control to execute programs, and its various counters and timers allow the microprocessor to implement right time decisions.

The 44A0131-26-0/2/9-US unit consist of two printed circuit boards that contain the microcontroller and the peripherals. The first PCB contains the processor, the RAM, the program memory and the firmware. The second board holds the I/O, communications, counters and timers. The two boards are connected together via a backplane bus.

The 44A0131-26-0/2/9-US has an input voltage range of 85 to 264 Vac and a digital I/O capacity of 4 to 192 points. Its far control features comprise of over-temperature, over-voltage and over-current protection and run-time fault detection. It also has a built-in security system in order to protect the data stored in the memory.

The controller is available in four memory types, namely the programmable logic controller (PLC), the distributed logic controller (DLC), the process control processor (PCP) and the process control movement (PCM). Each type of memory may use several programming languages and software tools in order to create programs. These provide improved scalability and suit custom applications.

The 44A0131-26-0/2/9-US unit is designed to process data quickly and accurately. It has high clock speeds, a number of programmable inputs and outputs, and various timers and counters to allow the processor to execute time-based decisions. It supports remote I/O communication and monitors environmental conditions such as over temperature and over voltage. The controller is suitable for small-scale applications requiring advanced control features and far control protection.
