Siemens 6ES7144-1GB31-0XB0 is a SIMATIC ET 200X EM 144 analog input expansion module for two current-measurement channels. Siemens documentation specifies bipolar current measurement up to plus or minus 20 mA, support for 4 to 20 mA signals, 25 ohm input resistance and connection of four-wire transducers. The module uses integrating conversion with 12-bit resolution plus sign and provides parameterizable diagnostics, limit alarms and channel monitoring. It is intended for decentralized acquisition of process-current signals in installed ET 200X stations. Engineers should verify the complete suffix, measurement range, channel wiring, shielding, data format, integration time and diagnostic configuration before replacement.
