Analog output module for ET 200X remote I/O
The Siemens 6ES7145-1FB30-0XB0 is an EM145 analog output module for the ET 200X remote I/O family, providing 2 analog outputs with a ±10 V signal range. This module fits into the ET 200X distributed I/O system, which is typically deployed in machine-mount or zone-level cabinets where the I/O is separated from the central controller by a fieldbus link.
Output range and wiring note
Each of the two channels delivers a ±10 V analog output — the full-scale span is 20 V, so the load impedance must be high enough to keep the output current within the module's drive capability (typically a few mA per channel). The ET 200X base unit supplies the module via the backplane bus; no separate 24 V field supply is needed for the analog section, but the base unit itself requires a 24 VDC power feed.
