Schneider Electric 140CPU11303

This Schneider Electric CPU module 140CPU11303 provides the performance needed in various applications. Its Lithium battery boasts impressive ratings of 7 µA and 210 µA, allowing for 1.2 Ah service life and ten years of shelf life €“ making it reliable over extended periods throughout frequent use.

Technical Description of 140CPU11303:

This CPU module 140CPU11303 resides on the local I/O backplane and acts as a digital brain for the Quantum system, controlling its internal storage of user instructions. It is also responsible for regulating all local, remote, and distributed inputs or outputs.

This 140CPU11303 model packs 368 kb of internal RAM and a full 250 ms watchdog timer, making users feel assured that their operations run smoothly. This device has an impressive clock frequency of 20 MHz and includes all the necessary components - except for the mathematical coprocessor.

This CPU module model offers two ports - an RS232 Modbus and a Modbus Plus protocol. Its bus's current demand is 790 mA, suitable for many industrial applications, while its weight of 0.3 kg makes it lightweight yet robust enough to meet any needs.

Boasting a powerful 3.95 W power dissipation, the model 140CPU11303 handles up to 16 K words of Ladder Logic. It provides 8192 input/output discrete capacity and 9999-word registers - ensuring reliable performance in any application.

Ambient Conditions:

Ensure optimal performance without compromising the maximum installation height of 5000 meters above sea level. Proper disposal requires that this product is collected on specific waste and never put into rubbish bins. As an added benefit, the model 140CPU11303 meets all standards concerning EU RoHS Directive since it has no mercury content.

Keep the ambient air temperature between 0 and 60 degrees Celsius for the 140CPU11303 CPU module's ideal operating environment, and store it at -40 to 85 degrees Celsius. Keeping relative humidity below 95 percent is essential in both settings.

General Information of Model's Switches:

Two rotary switches on the back of your CPU unit offer a smooth adjustment system to select either Modbus Plus node or port address settings.

Two switches designed to regulate memory security are located on the CPU's front panel - a 3-position slide switch situated farthest left offers total protection in its uppermost position and none when downwardly adjusted.

The three-position slide switch on the right enables Modbus (RS232) communication parameter settings to be selected. Easily access desired configurations to maximize efficiency and connectivity.

By setting the front panel switch to RTU or ASCII mode, a bridge connection is established by default between CPU hardware and Modbus controllers. In addition, these devices can access nodes on the Modbus Plus network once successfully logged in.

By adjusting the slide switch to its uppermost setting, users can enable ASCII functionality in this port while preserving an array of predetermined communication parameters.

Standard Safety Instructions:

Qualified personnel is essential for successfully installing, operating, servicing, and maintaining this analog module. The company does not take responsibility for any consequences resulting from its use.

This model 140CPU11303 is designed to streamline various industrial processes. However, it would help if you took extreme caution when using it on machinery without proper point-of-operation guarding. As inadequate protection can seriously harm the operator, utilizing this system with such conditions should be avoided at all costs.
