SIEMENS 6ES5430-4UA11

Siemens 6ES5430-4UA11 SIMATIC S5 Digital Input Module Description The 6ES5430-4UA11 is a digital input module for the Siemens SIMATIC S5 automation system. It provides 32 floating inputs for 24V DC signals, making it a crucial component for interfacing with sensors, switches, and other field devices in legacy industrial applications. This module is compatible with the S5-115U, S5-135U, and S5-155U PLC systems. Specifications Manufacturer: Siemens Product Series: SIMATIC S5 Model Number: 6ES5430-4UA11 Product Type: Digital Input Module Number of Inputs: 32 Input Voltage: 24V DC Input Type: Floating (potential isolated in groups of 16) Permissible Input Current: 7mA Input Delay: Typically 3ms Label Info Siemens SIMATIC S5 MLFB: 6ES5 430-4UA11 FS: 03 Application This module is used in a wide range of industries for machine control, process automation, and manufacturing tasks that were built on the Siemens S5 platform. It is ideal for spare parts inventory or for repairing existing systems to avoid costly full-system upgrades. Country of Origin Made in Germany. CO2 Impact Opting for a reconditioned 6ES5430-4UA11 module instead of a new alternative prevents the emission of approximately 20.0 kg of CO2. This saving corresponds to driving a car for about 100 kilometers. Availability This is an obsolete item, but it is available from our stock.

Which SIMATIC S5 PLCs is this module compatible with?This module is designed for use with the central controllers of the S5-115U, S5-115H, S5-115F, S5-135U, and S5-155U systems. Question? What front connector is required for this module?You need a Siemens S5 front connector with screw terminals, typically a 48-pole connector with the part number 6ES5497-4UA12 or a similar compatible version. Question? What does ‘floating’ or ‘potential isolated’ mean for these inputs?The inputs are galvanically isolated from the S5 backplane bus. They are organized into two groups of 16 inputs, where each group shares a common potential. This design prevents ground loops and protects the PLC’s internal circuits from external electrical noise and disturbances.
