Siemens 6ES7134-4GB11-0AB0 Analog Input Module

Siemens 6ES7134-4GB11-0AB0 is a Siemens ET 200S analog input module featuring 2 AI channels (2AI I 4Wire ST) designed for reading current-loop sensors in 24 V DC systems. The module accepts 4-20 mA signals with a 13-bit resolution, and offers 14-bit resolution for the ±20 mA input range, enabling precise measurement of process variables such as pressure, level, and temperature sensors that output current signals. It integrates into the ET 200S backplane in a Siemens S7 automation network, and the module address space is limited to a maximum of 4 bytes per module. This 24 V DC powered analog input module is commonly used to convert analog current signals from field devices into digital values for the PLC, supporting typical ET 200S applications in process and factory automation.
