Inputs accept standard 0–20 mA, 4–20 mA, and bipolar ±20 mA, making it a straight drop-in for pressure, flow, or temperature transmitters on 4–20 mA loops, plus the occasional ±20 mA signal from a load cell or valve positioner. Wire-break detection is active on 4–20 mA channels only – a line-down fault fires a diagnostic alarm that tells maintenance exactly which loop dropped, no guessing. Each input channel converts in 1.1 ms; the module cycles all four inputs in 10 ms maximum. That means a PID loop updating every 10 ms is practical – fine for most process control, tight for fast motion axes. Input resistance is 50 Ω for both 0–20 mA and 4–20 mA ranges – same burden voltage as most two-wire transmitters expect, so no re-scaling at the field device. ## Power budget and isolation Draws 12 mA from the backplane bus and up to 40 mA from 24 V supply. Bulkhead isolation tested at 707 V DC type test between channels and backplane. Reverse-polarity protected against destruction, and each module carries electronic short-circuit protection referenced to frame ground.","metaTitle":"Siemens 6ES7144-4GF01-0AB0 SIMATIC ET 200SP 4 AI/4 AO","metaDescription":"Siemens SIMATIC ET 200SP analog I/O module, 4 inputs (0/4-20 mA, ±20 mA) and 4 outputs. 35 mm deep, diagnostics, wire-break detection.
