Siemens 6ES7145-1FB31-0XB0 Programmable Logic Controller Module

Siemens 6ES7145-1FB31-0XB0 is a SIMATIC ET200X EM145 Analog Voltage Output Module that provides two output channels for the ET200X distributed I/O system. It functions as an extension module within Siemens automation configurations, delivering analog voltage signals from the controller to external devices. The 6ES7145-1FB31-0XB0 designation identifies the EM145 variant for ET200X and is intended for use in setups that rely on ET200X IO for analog control tasks. As part of the ET200X family, this module expands an automation installation with two independent analog voltage outputs, enabling additional analog control capability without replacing the central PLC. The EM145 is designed to integrate with Siemens automation architectures that use ET200X IO modules, making it suitable for panel or machine-line applications that require reliable, two-channel analog output within a modular, scalable I/O system.
