Two analog outputs, ±20 mA, for the ET 200X slice
The Siemens 6ES7145-1GB30-0XB0 is an ET 200X EM145 expansion module providing two analog output channels, each configurable for ±20 mA current loops. This module snaps onto the ET 200X backplane in the same IP65/67-rated enclosure as the CPU and digital slices, so the wiring runs through the same M12 connectors and the whole assembly takes the washdown environment.
