Siemens 6ES5430-7LA11 Analog Input Output Module

Siemens 6ES5430-7LA11 is a 32-channel digital input module for the SIMATIC S5-430 family, delivering 24 V DC floating input points for reading binary field signals. Designed to work with S5-115U/H/F controllers, this module plugs into the S5 I/O bus to extend input capacity without changing the CPU. It provides 32 discrete digital inputs, each accepting a 24 V DC signal, and its floating input configuration means the channels do not share a common return inside the module. In practical wiring, it is used to monitor devices such as pushbuttons, limit switches, and simple sensors, feeding states into the S5 PLC for synchronous scanning and logical decision making. The 6ES5430-7LA11 is part of Siemens' legacy SIMATIC S5 digital input lineup and is commonly cataloged with other DI modules in the 430-series family, allowing expansion of the plant’s digital signaling infrastructure within compatible S5-115U/H/F installations.
