Description
The Siemens 6ES5430-4UA13 is a digital input module designed for the SIMATIC S5-135U and S5-155U programmable logic controller systems. This module provides 32 isolated (floating) input channels, operating at a nominal voltage of 24 VDC. As a compact version (U-type) module, it is engineered for high-density signal processing in legacy industrial automation environments.
Features
- 32 digital input channels for high-density signal acquisition.
- Floating (isolated) input configuration for improved noise immunity and ground loop prevention.
- Designed for 24 VDC signal levels.
- Compatible with SIMATIC S5-135U and S5-155U rack systems.
- Compact module design for space-efficient cabinet installation.
