Siemens 6ES7144-4GF01-0AB0 is a SIMATIC DP electronic module for ET 200 PRO featuring four analog input channels (4 AI I High Feature). It accepts current signals in the ranges ±20 mA, 0–20 mA, and 4–20 mA and provides per-channel diagnostics to help detect sensor faults. The module is designed for DP backplane connectivity in ET 200 PRO systems and includes the DP bus module; the associated connection IO module (6ES7194-4..00-0AA0) must be ordered separately. It operates on 24 V DC (load voltage L+) and is intended for compact, rugged distributed I/O installations.
