Overview Manuals Applications Configuration & Programming Diagnostics & Protection Installation

Features:

  • Integrated 24V DC group-signal interrupt logic with edge-triggered processing
  • 8 individual digital input channels provided with 1-channel per group galvanic isolation
  • Front-panel green status LEDs for direct channel-by-channel signal verification
The Siemens 6ES5434-7LA12 digital input module is supplied under order code 6ES5 434-7LA12 as an original 8-channel 24V DC input hardware component.

Engineered specifically for SIMATIC S5-115U, S5-115H, and S5-115F controllers, this module handles fast binary signal acquisition and generates CPU interrupt requests via an onboard latching relay with accessible MELD contact.

The module requires a standard 46-pin front connector for signal wiring and occupies two bytes of input address space plus two bytes of output address space when interrupt evaluation is active in central or expansion subracks.

The Siemens 6ES5434-7LA12 digital input module is obsolete and discontinued by the manufacturer (OEM).

Description
Siemens 6ES5434-7LA12 digital input module provides high-speed binary signal acquisition for SIMATIC S5-115U, S5-115H, and S5-115F PLC systems. Equipped with 8 optically isolated channels grouped individually (1 channel per group), this unit safely processes 24V DC field signals while protecting internal controller electronics. Green front-panel LEDs provide immediate visual status monitoring for each input channel during operation.

Designed for high-performance industrial environments, the module incorporates group-interrupt evaluation triggered by positive or negative signal edges specified in the user program. Upon signal changes, a group signal drives an onboard latching relay with front-accessible MELD contact and a 24V RESET input for interrupt management. It operates effectively in central controllers or expansion units using appropriate interface modules.

The robust design utilizes standard 46-pin front connectors, ensuring secure signal wiring and easy maintenance in legacy factory automation architectures. Featuring a short input delay of 0.5 to 1.5 milliseconds, the module is ideal for monitoring fast sensors, safety interlocks, and critical process switches across manufacturing and process control applications.
