Siemens 6ES5430-4UA13 Analog Input Module 8-Channel

Siemens 6ES5430-4UA13 is a SIMATIC S5 digital input module (DI 430) that provides 32 optically isolated DC inputs at 24 V within the compact “U” version chassis. It’s designed to capture multiple discrete signals from sensors and switches and feed them into the S5-135U/155U PLC backplane, with compatibility to use in S5-115U systems when paired with the adaptor casing 6ES5491-0LB11. Each channel accepts a 24 V DC input signal, delivering reliable, high-density digital input coverage for control and monitoring tasks where numerous switch states or sensor events must be read simultaneously. This module is a drop-in DI 430 option in the S5-430 family, enabling scalable input handling in legacy Siemens automation setups without rewiring.
