Precision Analog Signal Generation for ET 200S Systems
The Siemens 6ES7135-4GB00-0AB0 electronic module provides four analog output channels for the SIMATIC ET 200S distributed I/O system. This module generates standard 0-10V voltage or 4-20mA current signals to control actuators and process instruments. Each channel features 12-bit resolution, delivering precise analog control with minimal drift. The module includes programmable diagnostics for detecting open-circuit or short-circuit conditions. It also supports configurable output behavior during CPU stop or bus failure. Furthermore, the compact design saves valuable space in control cabinets.
