Siemens 6ES7 134-4FB00-0AB0 Digital Output Module

Siemens 6ES7 134-4FB00-0AB0 is a two-channel analog input module (AI 2xU) for the ET 200S distributed I/O system used with SIMATIC automation controllers. It accepts voltage signals on two inputs with 13-bit per-channel resolution and offers selectable input ranges of +/-5V, 1..5V, and +/-10V, enabling precise sensing of analog process variables. As a standard ET 200S module, it is designed to be mounted in an ET 200S rack and integrated with compatible S7 controllers to capture voltage data from sensors and transducers in industrial automation applications. The AI 2xU designation denotes two voltage-input channels, suitable for converting analog voltages to digital values that can be processed by the PLC. This module is referenced in SIMATIC PCS 7 and ET 200S documentation as part of the analog input portfolio for S7-based systems, reinforcing its role in acquiring analog signals within a broader automation architecture.
