6ES7331-1KF02-0AB0 Siemens S7-300 Series Analog Input Module

6ES7331-1KF02-0AB0 SIEMENS S7-300 series PLC analog input module, the following details for you to introduce its technical parameters and product advantages.

technical parameters

basic information

• number of channels :8 analog input channels can collect 8 analog signals at the same time, which can meet the needs of more analog signal collection.
• input type : supports voltage and current input. The voltage input range includes ± 10V, ± 5V, ± 2.5V, ± 1V, ± 0.5V, ± 0.25V, ± 0.1V, etc. The current input range is ± 20mA, 0-20mA, 4-20mA, etc.

Electrical Characteristics

• Resolution :13 bits plus sign bit, which can provide high signal resolution and accurately convert analog signals into digital signals.
• conversion time : The typical value is 125 μs/channel. The fast conversion time enables the module to respond to changes in analog signals in time, which is suitable for application scenarios with high real-time requirements.
• accuracy : accuracy of ± 0.3%(at 25 ℃) at ± 10V, ± 5V, ± 2.5V, ± 1V, ± 0.5V, ± 0.25V, ± 0.1V voltage input; at ± 20mA, 0-20mA, 4-20mA current input, the accuracy is ± 0.3%(at 25°C).

isolation properties

• Isolation between channels : The channels are isolated from each other, which can effectively reduce the interference between channels and improve the accuracy of signal acquisition.
• Input and backplane bus isolation : The photoelectric isolation between the input signal and the backplane bus can prevent external interference signals from entering the PLC system and enhance the stability of the system.

other parameters

• Power consumption : About 2.5W, low power consumption, which helps to reduce the overall energy consumption and heat dissipation requirements of the system.
• Size : width 40mm × height 125mm × depth 118mm, compact design makes it take up less space in the control cabinet, easy to install and layout.
• weight : about 250g.
• Operating temperature range :0-60°C, which can adapt to a certain range of industrial environment temperature.
• Storage temperature range :-25-85°C.

• high resolution and precision :13-bit plus sign bit resolution and high precision, which can accurately collect analog signals and provide accurate data for control systems. It is suitable for industrial applications that require high measurement accuracy, such as chemical process control, precision instrument monitoring, etc.
• Multi-input type support : Support a variety of voltage and current input ranges, users can flexibly choose according to the actual sensor output signal type and range, improve the versatility and applicability of the module.
• fast conversion : the fast conversion time of 125 μs/channel can capture the change of analog signal in time, meet the real-time requirements of industrial automation system, and can be used for monitoring and control of high-speed dynamic process.
• Good isolation performance : The isolation design between channels and input and backplane bus effectively avoids signal interference and ensures the reliability and stability of signal acquisition. It is especially suitable for industrial environments with strong electromagnetic interference.
• compact design : small size and light weight, so that the module does not take up too much space during installation, easy to layout and integration in various control cabinets, and easy to expand and maintain the system.

Plain language sourcing guide for 6ES7331-1KF02-0AB0 Siemens S7-300 Series Analog Input Module

Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.

Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.

Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.

If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.

Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.

Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.

Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.

Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.

For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.

For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.

For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
