EM 144 expansion module with two ±10 V analog input channels for ET 200X
The Siemens 6ES7144-1FB31-0XB0 is an EM 144 analog input expansion module documented for the SIMATIC ET 200X distributed I/O system. Siemens specifies two voltage inputs with a ±10 V range, 12-bit resolution plus sign and channel-based diagnostics. The module is designed for IP66/67 field installation and uses 4/5-pin M12 circular connectors. Official technical data also identifies parameterizable diagnostics, diagnostic and limit alarms, hardware interrupts, channel overflow or underflow indication and no potential separation between the analog inputs. For replacement work, buyers should verify the complete suffix, ET 200X station design, M12 pin assignment, wiring, parameter set and installed revision.
