The integrating measurement principle covers ranges from -10 V to +10 V, 0 to +10 V, 1 V to 5 V, and -5 V to +5 V, with a per-channel conversion time of 1.1 ms and a full cycle time of 5 ms across all channels. The module is designed for the ET 200PRO distributed I/O family, mounting directly on machinery — the 130 x 45 x 35 mm footprint fits the standard PRO profile. ## Voltage input flexibility and diagnostic coverage The four analog inputs accept seven selectable voltage ranges, including bipolar ±10 V and ±5 V, unipolar 0–10 V, and the 1–5 V standard. The module detects wire-break and short-circuit conditions on the 1–5 V range, and a parameterizable diagnostic alarm reports group errors via the red SF LED. A hardware interrupt (limit value alarm) can be parameterized for channel 0, allowing the module to trigger a PLC event when an input crosses a threshold without polling. The integration time is selectable between 0.3 ms, 16.7 ms, 20 ms, and 60 ms, matching the line frequency for noise rejection. Each digital output is electronically short-circuit protected to frame, and reverse polarity protection prevents destruction on the supply side. The module draws 12 mA from the 3.3 V backplane bus and up to 40 mA from the 24 V field supply. ## Active lifecycle and sourcing posture The 8-byte address space and 707 V DC isolation test (type test) confirm compatibility with standard ET 200PRO bus couplers.","metaTitle":"Siemens 6ES7144-4FF01-0AB0 ET 200PRO 4AI, 4x 24 VDC Outputs","metaDescription":"Siemens 6ES7144-4FF01-0AB0 ET 200PRO analog module: 4 inputs, 4 outputs, 24 VDC, 1 A per channel.
