Siemens 6ES7144-5KD00-0BA0 SIMATIC ET 200AL AI 4xU/I/RTD IP67 Remote I/O Module

The Siemens 6ES7144-5KD00-0BA0 is a SIMATIC ET 200AL analog input module with 4 universal channels for voltage, current, or RTD/resistance measurement, each independently configurable. Rated IP65/67 with M12 5-pole I/O connectors and an M8 4-pole power connector, it mounts directly on machinery without a control cabinet and runs from a 24 V DC (20.4-28.8 V) supply across a -30 degC to 55 degC operating range.

Technical Specifications

Selection Notes

The four channels accept voltage (0-10 V, 1-5 V), current (0-20 mA, 4-20 mA), or Pt100/Ni100 RTD inputs independently per channel, so one module covers mixed sensor types on a machine without separate analog modules for each signal class. From FS02, the module supports safety-related tripping of standard modules to PL d / Cat. 3 / SIL 2, useful where an external safety relay needs a validated analog trip source. The -30 degC to 55 degC operating range and IP65/67 rating suit direct field mounting outside a control cabinet.

Applications

Suited to machine-mounted analog measurement points - temperature via Pt100/Ni100, process signals via 0-20 mA or 4-20 mA current loops, or 0-10 V transducers - where IP67 field mounting removes the need for a nearby control cabinet. The safety-related tripping support lets the module feed an external safety relay for functions up to PL d / SIL 2.
