Siemens 6ES7144-4GF01-0AB0 Electronic Module ET 200PRO

Siemens 6ES7144-4GF01-0AB0 is a SIMATIC DP electronic module designed for the ET 200 PRO distributed I/O system. This analog input module provides four current input channels (4 AI I High Feature) for process signals, supporting ±20 mA, 0–20 mA, and 4–20 mA ranges, with channel diagnostics to detect sensor faults or wiring issues. It operates from a 24 V DC supply on the backplane and uses a 3.3 V backplane bus; reverse polarity protection helps prevent damage from miswiring. The module is intended for ET 200 PRO installations and is typically paired with a corresponding bus module (included) and a dedicated IO connection module, 6ES7194-4..00-0AA0, which is ordered separately. The unit weighs about 0.178 kg and ships with packaging dimensions of 7.30 x 13.70 x 6.50 cm. It is RoHS compliant and part of Siemens' Analog expansion family for ET 200 PRO, enabling direct integration of four 4–20 mA sensors or transducers into PROFIBUS DP/ET 200 PRO networks.
