Siemens 6ES7144-1GB30-0XB0 Programmable Logic Controller Module

Siemens 6ES7144-1GB30-0XB0 is an ET 200X EM144 Analog Input Module for the Siemens ET 200X distributed I/O system, delivering two analog input channels for current measurements. It is the EM144-2AI variant and is used to connect current-loop sensors to a PLC network, providing two independent analog current inputs. The module specifies a maximum permissible input current (destruction limit) of up to 40 mA per channel, ensuring safe operation with typical 4–20 mA sensors and related current-loop devices in industrial automation environments. Designed to integrate with SIMATIC ET 200X hardware, it supports standard field-bus connectivity for decentralized I/O and is commonly deployed wherever precise current-input monitoring is required across remote sensor locations.
