Siemens 6ES7144-4GF01-0AB0 SIMATIC ET 200pro EM 4AI-I HF Remote I/O Module

The Siemens 6ES7144-4GF01-0AB0 is a SIMATIC ET 200pro high-feature analog input module with 4 current-input channels covering 0/4-20 mA and plus/minus 20 mA ranges. Resolution reaches 15 bit plus sign, with a basic error limit of 0.075 percent and a 10 ms cycle time across all channels, and it reports wire-break and short-circuit diagnostics per channel at 4-20 mA.

Technical Specifications

Selection Notes

The 4-20 mA range with wire-break diagnostics separates this module from a plain current-input card - a broken sensor loop reports as a diagnostic alarm instead of reading as a valid low value, which matters for process-loop monitoring. A 15-bit-plus-sign resolution and 0.075 percent basic error limit support precision transmitter readings that a lower-resolution 12-bit module would round away. Select the smoothing step - None, Low, Medium, or High - to trade response time against noise rejection for the specific sensor loop.

Applications

Process measurement in distributed SIMATIC ET 200pro stations - 4-20 mA transmitters for pressure, level, flow, and temperature loops, and 2-wire or 4-wire current-output field instruments needing wire-break detection.
