Core High-Density Input for S5-115U Systems
The Siemens 6ES5465-5AA12 is a 16-channel analog input module for the SIMATIC S5-115U programmable logic controller . This module converts analog signals from field sensors into digital values for processing by the S5 CPU . It supports input ranges of 0 to 20 mA and 4 to 20 mA, making it a versatile solution for process monitoring and control applications. Consequently, it is an essential component for connecting sensors like pressure transmitters and level transducers to legacy S5 control systems.
Designed for Industrial Environments
This module features a robust design and includes built-in EMI filtering and high input impedance to minimize measurement errors in electrically noisy environments . Each of the 16 input channels can be individually configured for current or voltage measurements, offering excellent flexibility . The 6ES5465-5AA12 provides a resolution of 12 bits plus sign, ensuring accurate measurement across the module’s 0°C to 60°C operating temperature range . Furthermore, its galvanic isolation between the input and the S5 bus protects the system from high common-mode voltages.
