Siemens 6ES7144-5KD50-0BA0 SIMATIC ET 200AL AI 4xRTD/TC IP67 Remote I/O Module

The Siemens 6ES7144-5KD50-0BA0 is a SIMATIC ET 200AL analog input module with 4 channels for RTD (Pt100/Pt1000/Ni100/Ni1000) or thermocouple (types B, C, E, J, K, L, N, R, S, T, U) temperature measurement, each independently configurable. Rated IP65/67 with M12 5-pole connectors, it mounts directly on machinery 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 cover RTD types (Pt100/Pt1000/Ni100/Ni1000) and thermocouple types B through U in one module, so a single ET 200AL station handles both sensor classes without a separate thermocouple module. Internal and external compensation-socket cold-junction compensation are both supported, which matters for thermocouple accuracy over the -30 degC to 55 degC operating range. Declared conformity to AMS 2750 and CQI-9 makes it a fit for heat-treatment furnace temperature-uniformity surveys that require those pyrometry standards.

Applications

Fits furnace and heat-treatment temperature monitoring where AMS 2750 / CQI-9 pyrometry compliance is required, and general-purpose RTD or thermocouple sensing on IP67 field-mounted ET 200AL stations.
