Number of channels: 8 Signal type: ± 5/10V, ± 20mA, 0/4 to 20ma Resolution: 16-bit Response Time: 55ms quarantine Voltage: 50V Operating Temperature Range: -25 ° C to + 60 ° C Supply Voltage: 24VDC SIEMENS 6ES7331-7 KF01-0 AB0 Analog Input Module is a high-performance industrial automation device. Designed for applications that require accurate measurement and control of analog signals.With eight independent analog input channels, it is capable of handling voltage signals of ± 5/10 V and 1-5V, as well as current signals of ± 20mA or 0/4 to 20mA. The module uses a 16-bit high precision converter to ensure the accuracy of data acquisition. In addition, it has a fast conversion time of 55 milliseconds, which makes the system more responsive.In order to ensure the stability and safety of the system, the module adopts the electrical quarantine technology to effectively prevent the influence of common-mode voltage, and can withstand a maximum of 50 V common-mode voltage. Operating temperatures range from -25 ° C to 70 ° C for harsh environments. With simple installation and configuration, users can easily integrate it into existing control systems for efficient data acquisition and processing.
