It reads resistive temperature sensors and standard thermocouples on the same channels, so one module covers both probe families on a single BOM line. ## What governs the field-side wiring Shielded cable runs are rated to a 30 m maximum, which is the distance ceiling between the slice and the sensor head — anything longer needs a head-mount transmitter or a different routing plan. That figure, not the PROFINET cable length, is the constraint that decides where the field box can physically live. Integration time is parameterizable in four steps — 1×, 4×, 16× and 64× the base cycle time — letting the controls integrator dial noise rejection against update rate per channel. Group diagnostics surface on a red/yellow SF/MT LED for the maintenance tech during a fault walk. Lifecycle stage for the seed MPN is recorded as current, so the part is on the manufacturer's active line and is the correct order code for a new BOM. No L* successor is recorded on the ledger, so the 6ES7144-6KD50-0AB0 is not flagged for cross-reference to a newer variant — specify it as written.","metaTitle":"6ES7144-6KD50-0AB0 Siemens Analog Input, 4 RTD/TC","metaDescription":"Siemens 6ES7144-6KD50-0AB0 distributed analog input slice for PROFINET, accepting Pt/Ni RTDs (100–1000 Ω) and TC types E, J, K, N.
